INTRODUCTION Designing a database for local train reservation system and trying to get an access to the database and reserve. This project deals with reserving tickets for the local trains which is heck these days .So inorder to make it convenient to travel we can book tickets priorily. This makes the travel smooth and convenient. This also helps in checking the details afterwards.

The FROM clause can include optional JOIN subclauses to specify the rules for joining tables. which restricts the rows returned by the query.30. Data manipulation The Data Manipulation Language (DML) is the subset of SQL used to add. A query includes a list of columns to be included in the final result immediately following the SELECT keyword."LF1". SELECT retrieves data from one or more tables.11. SELECT * FROM trainreservation WHERE source=”lingampally”. . and data access control. The WHERE clause eliminates all rows from the result set for which the comparison predicate does not evaluate to True. update and delete data: • INSERT adds rows (formally tuples) to an existing table.x."lingampally". e.10. Its scope includes data query and update. and originally based upon Relational Algebra.20.SQL (Structured Query Language) SQL (Structured Query Language) is a database computer language designed for managing data in relational database management systems (RDBMS).. The asterisk (*) in the select list indicates that all columns of the trainreservation table should be included in the result set. schema creation and modification.: insert into trainreservation("LF1". with optional keywords and clauses that include: • • The FROM clause which indicates the table(s) from which data is to be retrieved."Hyd". The most common operation in SQL is the query. The WHERE clause includes a comparison predicate. or expressions. An asterisk ("*") can also be used to specify that the query should return all columns of the queried tables. which is performed with the declarative SELECT statement.30).g. The query retrieves all rows from the trainreservation in which the sourcr column contains a value as lingampally. The following is an example of a SELECT query that returns a list of trains available. insert into passenger("xyz". SELECT is the most complex statement in SQL.21-03-10). ALTER. Data control The Data Control Language (DCL) authorizes users and groups of users to access and manipulate data. adding a column to an existing table.source varchar(20). DML operations: COMMIT causes all data changes in a transaction to be made permanent.tname varchar(20). Its two main statements are: • GRANT authorizes one or more users to perform an operation or a set of operations on an object. for example) in the database. Transaction controls Transactions. • DELETE removes existing rows from a table. • ROLLBACK causes all data changes since the last COMMIT or ROLLBACK to be discarded. Data definition The Data Definition Language (DDL) manages table and index structure. RENAME.. if available.: DELETE FROM trainreservation WHERE psgname = 'sss'. .g.: UPDATE passenger SET noofseats=2 WHERE psgname = 'sss'.arrival number(12.Destination varchar(20). usually irretrievably. • • DROP deletes an object in the database. ALTER modifies the structure of an existing object in various ways—for example.Noofseats number(3). Once the COMMIT statement completes.2)).• UPDATE modifies a set of existing table rows. Eg: create table trairnreservation(tname varchar(20).Noofseats number(3).date varchar(20)). The most basic items of DDL are the CREATE.g.2).. DROP and TRUNCATE statements: • CREATE creates an object (a table. leaving the state of the data as it was prior to those changes. Eg:create table passenger(psgname varchar(20). e. the transaction's changes cannot be rolled back. Commit.departure number(12. e. the Web browser can invoke them when it needs to without knowing in advance whether the method is implemented in the superclass or the subclass. the init() method is a good place to read parameters that were passed to the applet via <PARAM> tags because it's called exactly once when the applet starts up. In some cases the stop() method may be called multiple times in an applet's life. java. it should not use any CPU cycles. perhaps as a plugin. It's normally used to read PARAM tags. public void stop().applet. (It has others too. Your applet should use the stop() method to pause any running threads. when the applet is first loaded. Many applets you write will not have explicit start()methods and will merely inherit one from their superclass. The start() method is called at least once in an applet's life. and set up the user interface. public void destroy(). The init() method is called exactly once in an applet's life.Applet. A start() method is often used to start any threads the applet will need while it runs. the term typically also refers to programs written in the Java programming language which are included in an HTML page All applets have the following four methods: public void init(). For example. they do not have to override them. these are simply do-nothing methods. They have these methods because their superclass. when the browser leaves the page in which the applet is embedded. start downloading any other images or media files you need. public void start(). when the applet is started or restarted. . However. Many applets you write will not have explicit stop()methods and will merely inherit one from their superclass. sometimes running within the context of a larger program. The stop() method is called at least once in an applet's life. When your applet is stopped. In some cases it may be called more than once. For instance.) In the superclass. but right now I just want to talk about these four. This is a good example of polymorphism.[1][2] However. has these methods. which may be the default grant.• REVOKE eliminates a grant. public void init() {} Subclasses may override these methods to accomplish certain tasks at certain times. APPLET An applet is any small application that performs one specific task. Since they're declared in the superclass. The applet's start() method will be called if at some later point the browser returns to the page containing the applet. Most applets have init() methods. it's customary to stop playing an animation when the user clicks the mouse in the applet and restart it when they click the mouse again. . Java uses the standard. lines.awt. and all the methods of Graphics including those for drawing Strings.) The applet start() and stop() methods are not related to the similarly named methods in the java. For example. The stop() method would pause the video. If the start() method were called again. For example. GRAPHIC OBJECTS:In Java all drawing takes place via a Graphics object. Each draw method call will look like g. computer graphics coordinate system. This method is generally used to perform any final clean-up. Selecting the Reload menu item calls stop().Graphics. and then start playing it. circles. destroy(). selecting the Restart menu item calls stop() and then start(). but this is normally a bad idea. and init(). In the JDK's appletviewer. two-dimensional. Your own code may occasionally invoke start() and stop(). but not rewind it. the init() method might draw the controls and start loading the video file. 0). Buttons. if destroy() were called and then init(). the video would start over from the beginning. Frames. 50) where g is the particular Graphics object with which you're drawing. many applets will not have explicit destroy() methods and just inherit one from their superclass. Coordinates increase to the right and down.Thread class. just before the browser unloads the applet. The first visible pixel in the upper left-hand corner of the applet canvas is (0. rectangles. This is an instance of the class java. Only the environment should call init() and destroy(). Initially the Graphics object you use will be the one passed as an argument to an applet's paint() method. You get access to the Graphics object through the paint(Graphics g) method of your applet. (Normally the byte codes will also be reloaded and the HTML file reread though Netscape has a problem with this. Your own code can also invoke init() and destroy(). Drawing in Java starts with particular Graphics object. an applet that stores state on the server might send some data back to the server before it's terminated. For example. the video would pick up where it left off. Later you'll see other Graphics objects too. Each Graphics object has its own coordinate system. polygons and more.drawString("Hello World". However.lang.The destroy() method is called exactly once in an applet's life. Canvases and more. Everything you learn today about drawing in an applet transfers directly to drawing in other objects like Panels. it would not start over from the beginning. The start() method would wait until the file was loaded. in a video applet. 0. in that order. e. 50). 25).net. 255. 127.lightGray Color. 0) and so on. g.

If you can use a JDBC driver that works specifically for your database.change vendors and your applications only need to change their driver. Disadvantages A Java applet may have any of the following disadvantages: It requires the Java plug-in. JDBC presents a uniform interface to databases . and a JDBC driver. • • DATABASE CONNECTIVITY: Java Database Connectivity (JDBC) provides Java developers with a standard API that is used to access databases. This makes such applet much safer to run than standalone executable that it could replace. Some organizations only allow software installed by the administrators. some users can only view applets that are important enough to contact the administrator asking to install the Java plug-in. before your Java applications can access it. However signed applet can have full access to the machine it is running on if the user agrees. This makes applet with specific requirements impossible to run unless Java is manually updated. • Some applets require a specific JRE. Java automatic updater that is part of Java installation also may be complex to configure if it must work through proxy. There are plenty of drivers now for JDBC that support popular databases. the object tag needs workarounds to write a cross-browser HTML. a database.1. don't worry . This is discouraged [22].Sun provides a driver that is compatible with ODBC. • An untrusted applet has no access to the local machine and can only access the server it came from. security restrictions may make difficult or even impossible for untrusted applet to achieve the desired goals. To use JDBC. then that's great! If not. . As a result. Installing the first two should be straightforward. • Java automatic installation or update may fail if proxy is used to access the web. but finding a JDBC driver requires a little more effort. • Unlike the older applet tag. you'll need at least JDK 1. • As with any client side scripting. The JDBC to ODBC bridge comes installed as part of JDK1. You'll need to create an ODBC datasource for your database. • If applet requires newer or specific JRE than available on the system. so if this is your target platform. so you should be able to connect to any ODBC compliant database. the driver will already be installed.after that is re-test the applet in the appletviewer program or a web browser to ensure it conforms to security restrictions.1. the user running it first time will need to wait for the large JRE download to complete. regardless of the driver and database product. such as Microsoft's JVM. whose password is "sql".jdbc. // Create a URL that identifies database String url = "jdbc:odbc:" + args[0].exit(0). Our final URL looks like this : jdbc:odbc:demo To connect to the database. If this occurs. here's the URL for an ODBC datasource called 'demo'. and attempt to connect as user "dba". you need to perform some initialization first.odbc. but if your database vendor supplies a JDBC driver. and your application needs to check to see that the driver was successfully loaded.newInstance(). We'll be using the ODBC bridge driver. we might wish to use different drivers to connect to multiple databases. As an example.a URL just helps to identify our database. A JDBC URL starts with "jdbc:" This indicates the protocol (JDBC). we can connect to the database.err. feel free to use it instead. This is important. we'll only be using an ODBC database. We identify our database through a URL. we're not doing anything on the web in this example . because the application might be run on a non-Sun virtual machine that doesn't include the ODBC bridge.Connecting to a database In order to connect to a database. } We try to load the JdbcOdbcDriver class. and our application should exit gracefully. We take the name of the datasource from the command line.println ("Unable to load database driver"). System. We also specify our database in the URL. Once our driver is loaded. .err. System.println ("Details : " + cnfe). which selects the appropriate driver for the database we specify. and then catch the ClassNotFoundException if it is thrown. We'll connect via the driver manager class. } catch (ClassNotFoundException cnfe) // driver not found { System. // Attempt to load database driver try { // Load Sun's jdbc-odbc driver Class.forName("sun.JdbcOdbcDriver"). the driver won't be installed. Your JDBC driver has to be loaded by the Java Virtual Machine classloader. In this case. but in more complex applications. we create a string representation of the database. No. Statement objects support two main types of statements .executeUpdate ("create table employee { int id.executeUpdate ("insert into employee values (1. longs. we'll create a table that stores information about employees. we use a statement object to execute queries.// Now attempt to create a database connection Connection db_connection = DriverManager.next() ) { // Use the getInt method to obtain emp. // Insert an employee. id . ints. The response to a query will be returned by the executeQuery method as a ResultSet object. as well as strings. so the table contains data db_statement. // Create a simple table. connecting to a database doesn't take much code. you can call its executeUpdate and executeQuery methods.executeQuery ("select * from employee"). if needed. "sql")."). Such data types include numbers (bytes. "dba". A statement object is responsible for sending the SQL statement. shorts.createStatement(). Once you have an instance of a statement object. we can execute queries. timestamps and binary data. 'John Doe'). from the query. Executing database queries In JDBC. We'll keep things simple and limit it to name and employee ID. which stores an employee ID and name db_statement. // Commit changes db_connection.an update statement that is normally used for operations which don't generate a response. and a query statement that returns data. char(50) name }.").

To illustrate the executeUpdate command. and returning a set of results. booleans. doubles.commit(). // Create a statement to send SQL Statement db_statement = db_connection.

This is due to poor interfacing. will also show perfect results when run as a whole. adverse effect on any other or on the global data structures. validity and also determine any missing operations and to verify whether the objectives have been met. where in each module is tested to provide its correctness. Software testing is carried out in three steps: The first includes unit testing. So errors are rectified easily in particular module and program clarity is increased. causing serious problems. The final step involves validation and testing which determines which the software functions as the user expected. which may results in data being lost across an interface. In the completion of the project it is satisfied fully by the end user. Here also some modifications were. In this project entire system is divided into several modules and is developed individually. Errors are noted down and corrected immediately. . Unit testing is the important and major part of the project. The individual modules are clipped under this major module and tested again and verified the results. the software whose modules when run individually and showing perfect results. So unit testing is conducted to individual modules. It is the process of finding errors and missing operations and also a complete verification to determine whether the objectives are met and the user requirements are satisfied. It need not be the case. A module can have inadvertent.TESTING The testing phase is an important part of software development. Home page : .RESULTS: ScreenShots: 1. Train Details: 3.Check the availability of seats: .2. After booking the ticket: .4. 5.PRINTING TICKET: . 6.Seats not available: . Testcase_1 ScreenShot: .7. . Screen shot for seats are not available: .8:Testcase_2 ScreenShot: 9. . And database for update availability of seats which is available after the cancellation of ticket on that specific train . etc. He or she can also add some command buttons in the existing software and extend working of the software. FUTURE SCOPE If anyone wants this project then he or she can make an additional database of TRAINFARE. .CONCLUSION In the last we conclude that MMTs Railways is having a strong IT Infrastructure and a well equipped railway reservation system but there is some shortcoming in the system on which we have tried to work on it and successfully completed our project.
