You will find below a description of its main features. The right to create a trigger is defined along with the database's rights.

A stored procedure limits the number of round-trips needed between the client and the server machine. H y p e r F i l e S Q L • w w w. before deleting a row.) 65. On the other hand. deletion. etc. frame compression Logs A log is a special table where all the operations performed on one or more tables from a given time are automatically stored.1). (3. Automatic row lock HyperFileSQL supports locks at the table level and at the row level. H y p e r F i l e S Q L • w w w. • Cascading deletion: If a row is deleted from a table. 3G.g. Support for row locks allows for better access performance. Therefore you cannot delete a row from a table if this row is linked to other table rows (e. reducing the size of the frames increases performance noticeably. like all DBMS. In this context. the speed is so fast that the size of the frame only has a relative importance. cascading update It is easy to define integrity constraints. The cardinalities can be configured: (0. there's a big advantage to compressing frames. Transaction management is the best way to guarantee the coherence of a set of indissociable write operations on HyperFileSQL tables. for a remote access (DSL. this can be a benefit for contracts that bill based on volume of data. …).n).Integrity : constraint. A server's data transfer speed depends both on the frame travel speed over the network and the size of these frames. A frame is a data packet that travels over the network. c o m 7 .n). crash recovery A transaction is a set of indissociable operations: either all the operations in the transaction are performed. Transactions: commit. HyperFileSQL. rollback. especially if the connection speed is slow. Examples of referential integrity constraints: • Referential integrity: The referential integrity will prevent an author from being erased as long as there is at least one book referring to this author. w i n d e v. deletion. “Blob” data compression "Blob" type data (text or binary memo) can be compressed to optimize the space taken on disk. Reflexive links are supported. in other words: • the complete row before handling or modification by the user • the complete row after handling or modification by the user • the person who used or modified the record • the date and time of the operation or modification • the nature of the operation performed: addition. read • the id of the computer that performed the modification • the IP address of the computer that performed the operation • the name of the application that performed the operation It is possible to perform the following operations from a log: • restore the content of a logged table in case some data was lost or destroyed • restore the content of a logged table until a certain date • find the author. or none are performed. through relationship). modification. the corresponding rows in the linked tables will also be deleted (this constraint can be enabled or disabled. uses frames to communicate between the client and the server machine. you cannot delete a customer if there are invoices linked to this customer). The databases are isolated. Several databases on the same server HyperFileSQL natively supports the presence of several databases on the same server. (0. The space used can be significantly reduced. the date and the time of an operation performed on a specific row • keep the history of a table use (to compute statistics for example) These operations can be run using a command line or the WDLog tool. The referential integrity can be defined by link from the data model editor. The log contains the history of the table use. A transaction is used to ensure that updates performed on one or more tables have completed properly. Frame compression enables you to reduce the size of the packets (up to 95%) traveling on the network. Specific rights can be defined for each database. Since the volume of data transiting through the transmission media is reduced.n) . the size of the frame is more important. In a local area network. This prevents you from having to use multiple servers. (1. by automatically applying a data compression algorithm In a remote connection context. The speed for remote connection is improved. the link between a remote device and the server can be dropped briefly. You can save the entire server or only a single database. as long as you have the proper rights.Automatic reconnection This feature automatically takes care of dropped connections between client and server. disable programmed tasks by coding or through the administration tool. this problem occurs with hardware whose connection with the server is not always on: mobile devices (Wi-Fi. The tasks can be run at a set date. The application can resume without any error. as if the connection never was interrupted. When the application is reconnected. HyperFileSQL supports hot. H y p e r F i l e S Q L • w w w. differential backups. for example. it allows. or execute additional processes if you want. or a selection of tables. 3G. Usually. …) notably. etc. A task doesn't only mean allowing the execution of a stored procedure (UDF). we need to resume the application at the point where the connection was interrupted. The definition is done through the Control Center or by programming. In Wi-Fi connection for instance. The number of backups to keep can be specified. copy the backup on the network. The schedule for a complete backup and a differential backup can be specified (example: 1 full backup every month and 1 differential backup every week). Integrated sequencer (scheduled tasks) HyperFileSQL includes an integrated sequencer that allows you to define scheduled tasks. with or without index. • Number of times the task must be executed (10 times or no end date for example). without disconnecting users • transparently. with one or more regular intervals. modify. A backup is portable. A backup can be triggered from the Control Center (instant backup. to perform batch processes. all the buffers and positions are stored and reassigned. scheduled backup). directly from the application. or from a Client/Server version to a Classic version. With the automatic resume. enable. but also allowing a backup or an automatic performance optimization to be triggered. Backup Configuration of a backup Backing up is an extremely important feature for databases. without disturbing the running of the applications. The execution of a stored procedure before and/or after the backup allows for automated processes to be run: send e-mail. Using the sequencer is more performing than running the commands in the Windows task scheduler or the Linux "cron" process. The sequencer allows the DBA to program the automatic execution of tasks on the server. or the 4th of every month for example) • At a given time or every n hours and/or minutes. You can create. and make sure the buffers are accurate. This can also happen on regular wired networks.You can also manage the connection interruptions by programming. add. c o m 8 . w i n d e v. or by coding. The backup can be performed: • on the live database. from Windows to Linux for instance. Graphical and user friendly interface of the sequencer (scheduled tasks) Example of possible parameters: • Every month or only some months • Every day or only some days (every Mondays. Automatic data modification for each site (SDD) Which programmer. A 100-version history is kept. or to change a data type in a column? The problem is even more complex when several different versions of the application are in use: you need to check the version of the database as well. or still if the data type is changed (integer to real for instance) HyperFileSQL will automatically update the data in the relevant tables.

Clustering is also very useful for SaaS infrastructures. most Information Systems use several heterogeneous databases. The tuning of rights is very granular: at the server level.
