Mike Richardson and John Dean are pleased to announce the 2.0 release of Rekall, a personal, programmable DBMS system for Linux and Windows. If you want to distribute your Rekall application commercially then there is a run-time version of Rekall V2.0.0 available too. There are also versions available for the Sharpe Zaurus and Compaq iPaq. Rekall is the only viable alternative to MS Access for Linux. With Rekall you will be able to quickly and easily build database applications using Rekall forms and reports. A full complement of widgets means that applications built in Rekall will be able to have the look and feel of any other application. Rekall applications can be extended in their functionality to perform virtually any task via embedded Python as a scripting language.
Ever since the release of dBase many years ago, the idea of a programmable DBMS has become increasingly popular. Major systems have been written in applications like Paradox and MS Access. By focusing on the database, users are able to leverage their business knowledge into working applications. One of the limitations of the aforementioned products is that their native database didn't scale well or support multiple users very well. Rekall avoids this problem by dispensing with a native database.
The biggest addition to Rekall 2.0.0 are reusable components. Rekall now comes with a selection of components that you can use in forms; these include standard buttons and navigation tools.
In addition to these components, you can also construct your own for use as often as you want. You can store your components either in the database itself, or in a local area in the file system.
To support reusable components, and to make it easier to script complicated forms, Rekall 2.0.0 introduces an Event/Slot mechanism (akin to Qt's Signal/Slot mechanism). This allows to place all script code which is
logically associated with a particular control inside that control, and means you can copy or delete the control without worrying about copying or cleaning up script code inside other controls.
Other new features in Rekall 2.0.0 include:
- Static images can by displayed in forms
- Data controls can appear in menu-blocks
- Spin box control
- Link controls can display multiple colums
- Link controls can use Queries as well as tables
- Event logger for debugging
- Raw SQL window for direct SQL execution
- Forms, Reports, etc. can run modally
- Fast table filters for predefined table data display
- Modal forms can be used as dialog boxes
- Explanation of queries generated by Rekall
- Menu and toolbar hiding
- MySQL and PostgreSQL connections over SSH tunnels (Linux only)
In addition, Rekall comes with a thorough demonstration database that illustrates the various features of the applications. There are actually three copies of the database, one using MySQL, one PostgreSQL and one using XBase/XBSQL. Optional drivers are currently available for DB2 and ODBC with Oracle 9i coming later this summer (the Windows version of the Oracle 9i driver is available now).
