It is a useful technology for delineating the steps that must be taken, the dependencies that must be enforced, and the approvals that must be obtained during the completion of projects. It keeps track the information about the employees and also it keeps track of the task assigned to each employee. The super users of the system are the ‘ADMIN’ and the ‘EMPLOYEES’ of the different departments allocated by the admin in an organization or company. The ‘VIRTUAL OFFICE’ mainly consists of eight modules Administrative module, Login module, Bulletin board, E-forum, Task management module, Project management module, Address book, Documents library and lastly Logout. In the administrative module administrator the admin may be the owner of the site, he can create a new employee and can assign a password to them. Login module consists of Login Registration, Changing password, Password Reminder. Where actually a new user can register and the existing user can login with user id and password. E-forum is discussion software allows people from within a corporation to exchange work and ideas. Included in the software are links to other intranet resources, so that from within a discussion, people can link out to a Web page on the Internet or intranet, or can even link into intranet databases. Project management module gives employees task status reports. We can assign a task to an employee, can view status of all tasks and also can view today’s report of all tasks. Address book module mainly maintains information about all employees addresses where we can view addresses of all the employees. Document library module contains the list of documents available in document library and it also allows posting documents. 5 INDEX Chapter Chapter 1 Introduction Of Intra Mailing System Introduction Project Type Project Scope Project Outline Administration User Role Project Background Project Objective & Benefits Project Specification Prooject Review Chapter 2 Software & Hardware Requirments Hardware Rquirements Software Requirement Chapter 3 Software Rquirement Specification 6 Existing System Proposed System Limitation Related Work Technical Feasibility Economic Feasibility Oprational Feasibility Module Description Administrative Module Login Module Buletin Board E-Forum Project Management Module Pageno. 8-11 8 8 8 9 10 11 11-12 12 13-17 13 14 14 15 15 16 .

There is link in the page for the Registration of New user and another link for the forget password for the employees who have forgot their password. where he can have an access to the company’s Database with some constraints basing on his designation. PROJECT SCOPE: VIRTUAL OFFICE is an Enterprise Intranet Application that automates and improves procedures within organizations. 9 . which is an html file where the user can Login to the company’s website where he can access his account details.Chapter 1 INTRODUCTION PROJECT TYPE: Web Based Application. and the approvals that must be obtained during the completion of projects. It keeps track the information about the employees and also it keeps track of the task assigned to each employee. the dependencies that must be enforced. PROJECT OUTLINE: The Application starts with a login page. . he can do his Work of doing project tasks there . The super users of the system are the ‘ADMIN’ and the ‘EMPLOYEES’ of the different departments allocated by the admin in an organization or company. It is a useful technology for delineating the steps that must be taken. This is called as “Employee Details” He can view the “Documents” which are needed for his project. Some of these benefits are: • It provides a consistent approach to projects in an organization • The project success rate is increased. Employee can interact through online for doing his regular works which will be done at regular conventional office. He can view the “Announcements” which are given by the Administrator. There are many benefits for an organization that opts to follow a standardized Process or method when investigating. This project information will assist management in ensuring that projects underway within the organization are strategically aligned to the business and that the important projects are receiving the priority required. initiating and managing projects. It also allows management to check that the project is being managed effectively. 10 . He can view his details and can modify if any changes needed. USER ROLE: Employee can login with his id and password. PROJECT BACKGROUND: The Virtual office is being charactered to decrease the wastage of time for the employee.ADMINISTRATION: Administration processes are simplified allowing more time for management of resources. ultimately saving costs • It raises the skill of project managers in the organization • A common knowledge base is created reducing project risks. the secondary objectives (and benefits) are as follows Seeking a low-risk alternative to renting a conventional office. PROJECT SPECIFICATION: The Portal Administrator role would typically be allocated to an individual working in the project office. Seeking supportive business services such as answering services. agreements with suppliers etc. administration and management of projects and who has authority in these areas. for corporate image purpose. It avoids the unnecessary emailing of large documents to several team members and the risk that documentation could be mislaid. minutes of meetings. Testing a new product or service idea. Migrating from using post-office box. Virtual office contains a documentation repository per project and a general repository of project management templates that can be used by the project managers and team members. This facility enables the easy sharing of documentation by team members and also assists in ensuring that the latest version is always centrally available to the team members. training documentation. Up-to-date.e. The repository enables all team members to upload specific documentation relating to the project i. Seeking to establish a business presence in the provider's country or city. relevant documentation is a critical requirement for a successful project. specification documentation. If your organization does not have a project office. Seeking a business address within an expensive location. Downsizing from a conventional office. Connecting Employees to the company site through online. 11 . it should be someone who is involved in the overall prioritization.Project Objectives and Benefits The primary objective of the virtual office is to fully automate the conventional office. Seeking a business address as its registered business address for complying to government regulation. project plans. PROJECT REVIEW: The cost of using project portal is based on the number of users requiring access to the portal with annual and monthly payment options available. Costs are also dependant on: • Implementation assistance required • Amount of disk space required • System administration services • Hosting requirements (on-site hosting is available) • Customization requirements • Support requirements Chapter 2 12 . MS Sql Server Application Designing Software: HTML 5. 16 bit Software Requirements: Operating System: Microsoft’s Windows NT Server Software: Internet Information Service Database. 256 colors 1024x768. wampsever 2.0.0i Chapter 3 13 .SOFTWARE AND HARDWARE REQUIREMENTS Hard Ware Requirements: Components Minimum Recommended Processor Pentium IV Pentium IV Clock Speed 450 MHz 700 MHz Random Access Memory 128MB 256MB Hard drive disk space 3GB NA Video 800x600. php. Lack of government regulation. And this system would be a Best of its kind. Usage by fraudulent companies due to ease of registration.SOFTWARE REQUIREMENT SPECIFICATION Existing System: Existing systems have has all the features above discussed and it’s a third party maintained software to do the tasks like calls receiving and forwarding and handling of mails and messages receive by us and helps in the business. Limitations: High volume of companies using the same address. We imposed certain security constraints like session Management. any where access. Advantages:These Systems are now available as Software products in the market so that we can buy them and use. as it is a niche industry 14 . Proposed System: Proposed system is mainly concentrating upon creating virtual Environment for the employees of specific company. One more Advantage of this system is they will interact and can cooperatively work with the new media technologies like mobiles. resulting in fly-by-night providers. They are cryptographically poor. Disadvantages:All the systems in the Today markets don’t have certain security constraints. Lack of structured training of service staff. Here. They are: Technical Feasibility Economic Feasibility Operational Feasibility Technical Feasibility: The feasibility study involves knowing whether the project can be developed with the help of current equipment. Operational Feasibility: The study involves in finding whether the system will be used if it is developed and implemented or there will be any resistance from the user due to development of system.Related Work: Our project Virtual Office mainly deals with maintaining. Feasibility analysis: Feasibility study is an important concept in any system development. No other special requirements are to be created just for the system development. It is made mainly into 3 aspects. 15 . Economic Feasibility: Economic Feasibility involves cost to develop and install the system. the check is done whether the organization can meet thee costs involved in developing the project or not. The system is technically feasible. The employees can login into the site and can do their work. existing software technologies. employees etc. And to automate the tasks in the conventional office that are usually done by the employees. The organization contains required equipment and the required software and the employees. It should be noted always how far the system will be feasible on way in its development and after development. storing the employee and project details in databases. used for everything from advertisements by extracurricular groups and local shops to official notices. Bulletin boards are often made of a material such as cork to facilitate addition and removal of messages or it can be placed on the computer so people can leave and erase messages for other people to read and see. It just acts like notice board where one can get all the information about the activities which were going on in all departments. 16 . pin board or notice board in British English) is a place where people can leave public messages. Where actually a new user can register and the existing user can login with user id and password. Password Reminder. for example. Login module: Login module consists of Login Registration. Not only they can view they can also post their own articles. Changing password. if not hundreds or thousands of public bulletin boards. to advertise things to buy or sell. announce events. or provide information. he can create a new employee and can assign a password to them. Bulletin boards are particularly prevalent at universities.Module Description: The ‘VIRTUAL OFFICE’ mainly consists of eight modules Administrative Module Login module Bulletin board E-forum Project management module Address book Documents library and lastly Logout Administrative Module: In the administrative module administrator the admin may be the owner of the site. Bulletin Board: The Bulletin board is an important module where all the employees can see the articles which were putted on notice board. Many sport dozens. A bulletin board (pin board. Forum software packages are widely available on the Internet.E-Forum: E-forum is discussion software allows people from within a corporation to exchange work and ideas. while forums require the member to visit the website and check for new posts. 17 . We can allocate the project tasks to various employees in the office. Project Management Module: Project management module gives employees task status reports. a newsreader. whereby members can choose to be notified of new posts in a thread. Because members may miss replies in threads they are interested in. Project manager can view the employees work details like how many hours have been Address Book: Address book module mainly maintains information about all employees addresses where we can view addresses of all the employees. The main difference between newsgroups and forums is that additional software. One significant difference between forums and electronic mailing lists is that mailing lists automatically deliver new messages to the subscriber. Visiting and participating in forums normally requires no additional software beyond the web browser. can view status of all tasks and also can view today’s report of all tasks. and web feeds that allow members to see a summary of the new posts using aggregator software. many modern forums offer an "e-mail notification" feature. Included in the software are links to other intranet resources. people can link out to a Web page on the Internet or intranet. so that from within a discussion. is required to participate in newsgroups. or can even link into intranet databases. We can assign a task to an employee. Document Title .the document category that best fits the document you are uploading. 2. Owner . 4. 6. Remember. Document Description . click the "Upload Document" link on any Virtual Office web Page.the list of groups you would like to have access to this file. Category . Who may view (download) this file .a brief document name. This field is filled in automatically by the Virtual Office. File . By default. a document will be accessible to all groups. Rename suspicious files before uploading them to the Virtual Office. Document categories are used simply to facilitate searching by dividing the Documents contained in the Virtual Office into logical groups. 3.Documents Library: Document library module contains the list of documents available in document library and it also allows posting documents.a brief description of the contents of the document. or users will have problems trying to download the file. Filenames should always include a proper 3-letter extension. Only the Virtual Office administrator can add or edit the list of document categories.the user who is currently uploading this document. Fields to fill out when uploading a document To upload a document. the information you Provide about the document is used to allow other users (or even yourself) to search For and find the document later: 1. you should log out and log in again as yourself.click the button to locate the file on your local computer that you wish to Upload. Fill out the fields as completely as possible. meaning that any other user can download the file. which recognizes each user? NOTE: If this User is not you. 5. You can restrict download of the file to one or more Chapter 4 18 . easy to understand and easy to use. which provides less analysis effort. A model is a simplification of reality.SOFTWARE DESIGN Object oriented analysis Object oriented analysis is concerned with developing software engineering and specification that expressed as a systems object model as opposed to traditional data or functional views of a system . less complexity in system design and easier verification by the user reusability of the analysis artifacts which sales time and costs. 19 . specifying. after exposing opportunities for simplification and reuse we build models to manage risks. constructing and documenting object oriented system is exactly the purpose of UML. productivity games through direct mapping to features of data modeling .UML is standard language for writing software blue prints. We built models to better understand the system we are building. and depending on the analysis model and programming language. It is very expressive language. Data Modeling: Modeling is a central part of all activities that ads up to deployment of good software we build models to communicate the desire structure and behavior of a system we built the models to visualize control system architecture. Unified Modeling Language:Visualizing. Modeling is proven and well accepted engineering technique.OOA can yield following benefits maintainability through simplified mapping to the real world. addressing all the views needed to develop and then deploy software systems. Graphically it is a collection of vertices and arcs. Some times these arcs are represented with extension symbols and different form to represent different types of relationships. Definition: A class diagram is graphical notation that shows set of classes. Collaboration is society of classes. Class Diagram: Class diagram are the back bone of object oriented modeling. collaboration relationships between them thus class diagram represent design view of a system. interfaces that connect together with common specifics operation implementation. services of system to end users. The executing system is map of interacting objects that maintain their own local state and provides operation on the state information. It models simple collaboration. collaboration and their relationship graphically. These diagrams are built with structural things like classes. document. An Object Oriented Design process involves designing objects and relationships between these classes. interaction.Object oriented design: Object Oriented Design is design strategy where system designers think in terms of ‘things’ (objects) instead of operations of functions. specify. structure of system that is definition. It models vocabulary of system. This means defining abstraction from information which is a part of a system. Class diagram shows static descriptive view of system diagrams visualize. The various UML diagrams for the various sub system involved in our website are given below. interfaces. the required objects are created dynamically using class definitions. Advantages of class diagrams: It designs static view of a system. This view provides functions of systems. construct. Classes represent an abstraction of entities common and characteristics. classes and interfaces are represented as vertices on relation ships as arcs connecting classes together. Associations represent the relationships between classes. When design is realized as an executing program. 20 . 21 . That is used to model the instances of classes and interfaces. modeled in class diagram.Components Diagram: Component diagram models the instances of things continue in classes’ diagrams. 22 . A component diagram is collection of vertices and arcs between vertices here component are acted as vertices and arcs represent relationships between vertices. relationships defined. A component diagram that shows set of components and their relationships at a point in time. Use Case Diagrams: Use case diagram identify the functionality provides by the system (use cases). Example: lodges a complaint. Thus use case diagram models use case view of a system. extent. use cases Generalization between actors Include . generalization relationships Common uses of use case diagram: Provides high level view of a system with respect to user To model context of a system Determine human system interaction The basic components in use case diagram are: Use case Actor Association Use case: It is functionality provided by system to user. actors and relation ships between actors use cases A use case diagram contains: Use cases Actors Association relationship between actors. This model behavior of a system with respect to users it shows the dynamic aspects of the system then user interact with the system. Definition: A use case diagram is set of use cases. provides user id and password Use case is represented graphically as ellipse with name inside it Actor: An actor is a user of a system of data base in a system it is represented with stick figure Association: Association links actors to use case explain in what way and how actor interacts 23 . identifies users who interact with the system (actor) and provides association between users and use cases. A use case can have all possible interactions of users with use case graphically. 24 . Sequence diagram: A sequence diagram is an interaction diagram that emphasizes the time ordering of messages. This commonly contains Objects Links Messages System level sequence diagram 25 . A sequence diagram shows a set of objects and the messages sent and received by those objects. Login: 26 . View details sequence diagram: 27 . Articles: 28 . Collaboration Diagrams: 29 . . 30 . Most common usage scenarios client connects to SQL server and request some information where up on SQL server processes the requests and return results the client must then interpret and display results. Data warehousing: It includes tools for extracting and analyzing summary data for online analytical processing it also includes tools for visually designing databases. Features: Scalability and Availability: It supports features such as federated servers. indexed view and large memory support that allow it to scale performance levels.Microsoft SQL server 2005: Microsoft SQL server is a relational database management system that can be used by individuals or business for storing and managing the data. 31 . Microsoft SQL server is a scalable database system whose primary purpose is to serve as a backend database for a client program. It also offers powerful functionality for data analysis and reporting SQL server 2005 is major milestone for Microsoft which is trying to position itself in database market. The development of software starts with requirement document and is there fore important that requirement specification contain no error and specifies client’s requirements correctly. testing and previous. According to pressman “validation criteria” is probably the most important. Transaction and queries are performed in order to check various inputs and expected outputs. and. verification is a processes of determining whether are not the products of given phase of software development fulfill the specification established during the previous phase. Validation is a process of evaluating the software the software at end of software development process to find out how well the software satisfies requirement specification. The review processes is generally done by group of people including author of product. consistency and testability of the requirements. ironically.Chapter 5 VERIFICATION & VALIDATION Validation Specification: The terms verification and validation are used interchangeably. queries and reports. The activities include providing. Proper execution of reviews is critical to successes of project. 32 . The major verification and validation activities for software development are transactions. Requirement verification also checks the factors as complete ness. These outputs are checked against the existing document to see whether they are matching or not. Reasonable expectations are defined in SRS under this section and user visible attributes of software are also defined here. system design. How do we recognize successful implementation? What losses of tests must be conducted to validate functional performance and constrains? Specification of validation criteria acts as an implicit review of all other requirement. design code and test plan. The validation process of evaluating deployment system at an end is must. The primary purpose of review was to detect the defects at different stages during the project. detail. The review material usually includes specification. department head and a person from each phase preceding and succeeding the current phase under review. to ensure that it meets all necessary requirement specifications. the most often neglected section of SRS. Inspections and reviews are performed in order to be careful with calculations being made. Information contained in this section forms the basis for a validation testing approach. Testing principles: All tests should be traceable to customer requirements. behaviors and performance. Black Box Testing: Black box testing focuses on the functional requirements of the software. For effective testing. As specified design space the inputs are considered. The highly error prone components of the software products should be recognize and thoroughly exercise. team should be a third party rather than developer and client The physical system specifications are turned over to programmers at the part of the implementation space. design and code generation. Test should be planned long before testing begins. FUNCTION ORIENTED TESTING: This can be broadly classified into two categories based on the area in which tests are conducted. We have to design a series of test cases that have high likelihood of finding errors. The testing should start from small components to large components. some time called glass box testing is a test case design method that uses the control structure procedural design to drive the test cases.Chapter 6 TESTING Software testing is a critical element of software quality assurance and represents the ultimate role of specification. The test was extensively conducted and checked against the specification given in the design phase module. actual processing that goes on with in the system and final output. software must be tested to uncover as many errors as possible before delivery to consumer. They are White box testing Black box testing White Box Testing: White box testing. It enables the software engineer to derive the sets of input condition for a program. 33 . The strategies provide systematic guidance of designing tests that Exercise the internal logic of software components and Exercise the input and output domains of program function. Once the source code has been generated. 34 .Unit Testing: Here the entire software system is tested. Testing here focuses on the external behavior of the system. Acceptance Test: This is normally performed with realistic with data of the clients to demonstrate that the software is working satisfactory. Boundary Condition Test: Boundary conditions as in the case of generating sequences ware tested he ensure that module operates properly at boundaries establish to limit of restricts processing. The reference document for the processes is requirement document and the goal if system meets its requirements. This method of analyzing data is called “Normalization”. by removing repeating terms showing them as separate records but including in them the key fields of original record. NORMALIZATION: The first stage of normalization is to reduce the data and to its first normal form. and so such.Chapter 7 DATABASE DESIGN Data bases are normally implemented by using package called database management system (DBMS). One of the most useful methods of analyzing the data required by the system for the data dictionary has developed from research into relational database. UN normalized data are converted into normalize data by three stages.F Codd. 35 . Each stage has procedure to follow. general technique for the database are limited. particularly the work of E.Each particular DBMS has some what unique characteristics. all the items in each record are entirely dependent on the key of the record.The next stage of reduction to the second normal form is to check that the record. This is done until each record contains data items. but on other data item. which are entirely dependent on the key of their record. LOGICAL ACCESSIBILITY: Every data item value stored in relational data base is accessible by stating nature of table it is stored name of column under which it is stored and value of primary key that defines the row in which it is stored. then it is removed with its key to form another record. Associations between data items are not logically represented in any other way. RELATIONAL DATABASE MANAGEMENT: A relational database management system only its relational capabilities to manage the information store in its databases. 36 . INFORMATION REPRESENTATION: All information stored in a relational is represented only by data items values. If there are any item there are removed to a separate record leaving one of items behind in the original record and using as the key in the newly created record. such as a use of pointers from one table to another. The final stage of analysis. the reduction of third normal form involves examining each record which one is in second form to see whether any items are mutually dependent. which are stored in tables that makeup the database. If a data is not dependent on the key of record. which one is first normal form. REPRESENTATION OF NULL VALUES: The database management system has a constitute method of representing null values. This is done so that facilities of relational database management system itself can be used to maintain database description. null values for numeric data must be distinct from zero or any other numeric and for character data it must be different from string of blanks or any other character value. For example. CATALOGUE FACILITIES: The logical description of relation database is represented in the same manner or ordinary data. 37 . whether are not the database management system itself supports distributed databases.DATA LANGUAGE: The relational database management system may support many types of languages for describing and accessing database. INSERT. However. there must be at least one language that uses ordinary character strings to support the definitions if data. manipulation of data. UPDATE & DELETE: Any operand that describes the result of single retrieval operation is capable of being applied an insert. LOGICAL DATA INDEPENDENCE: Changes made to tables that do not modify any data stored in that table. 38 . VIEW UPDATABILITY: Any view that can be defined combination of basic tables that are theoretically updatable. update or delete operation as well. PHYSICAL DATA INDEPENDENCE: Changes made to physical storage representation or access methods do not require changes to be made to application programmers. INTEGRITY CONSTRAINTS: Constraints that applied to integrity and referential integrity are specifiable by the data language implemented by the database management system and not by the statements coded into the application programs. information concerning authorization and the boundaries for recovery of units. constrains on data integrity. the definition of views. these capitals of being updated by the relational database management system. DATABASE DISTRIBUTION: The data language implemented by the relation management system supports the ability to distribute database without requiring changes to be made to application programmers this facility must be provided in the data language. do not require changes to be made to application programmers. The model does allow for what is called inheritance in object oriented terms. identifying the fundamental things. CONCEPTUAL SCHEMA: A conceptual schema or conceptual data model is a map of concepts and their relationships. This describes the semantics of an organization and represents a series of assertions about its nature. which describes the semantics of an organization without reference to technology. This is as opposed to a conceptual data model. Without being specific to a particular database management product. object-oriented classes. about which it is inclined to collect information. it describes the things of significance to an organization (entity classes). which describes the particular physical mechanisms used to capture data in a storage medium. A data model can be as concrete as each person's perspective. and not a database design. LOGICAL SCHEMA: A Logical Schema is a data model of a specific problem domain that is in terms of a particular data management technology. and characteristics of (attributes) and associations between pairs of those things of significance (relationships). it is in terms of either (for example. These are consolidated into a single conceptual schema that is the superset of all of those external views. The set of instances of an entity class may be subdivided into entity classes in their own right. Thus. each instance of a sub-type entity class is also an instance of the entity class's super-type. it may exist on various levels of abstraction. Because it represents the semantics of an organization. If that person's world changes. of which the things an individual deals with are but examples. Conceptual data models take a more abstract perspective. Each instance of the super-type entity class then is also an instance of one of the sub-type entity classes. 39 . The original ANSI four-schema architecture began with the set of external schemas that each represents one person's view of the world around him or her. Specifically. or XML tags. but this tends to make it inflexible. in 2007) relational tables and columns. or a physical data base model. an application programmer using this type access is prevented from by passing entity integrity or referential integrity constraints that are defined for the database.NON SUB VERSION: If the relational database management system supports facilities that allow application programmers to operate on that table or a row at a time. the model must change. Chapter 8 OUTPUT SCREENS 40 . 41 . 42 . 43 . 44 . 45 . 46 . 47 . By this application employees in the organization can easily update their day to day work and they can easily clarify their doubts and get the information what ever he want for example details of their other employees and can view different documents and Articles what are available and they can post and update their own Articles and documents and by this department heads or who are super users get the details of employees and their daily work progress and status of work assigned. The system behavior was found to be as expected in the problem definition. and details So by this The Employees can now use the online system to do their usual work in the office.Chapter 9 CONCLUSION The application was tested and implemented successfully. 48 . but we are trying to get it in the internet where employees can sit in their home and can login into their workspace provided by company. We can implement the chatting facility between the employees which help them in their way of doing projects.Chapter 10 FURTHER ENHANCEMENTS Implantation of chatting We emphasize mainly on intranet application which will work in the same office. 49 .
