File Extension DB

File type: Borland Paradox database file

About the DB file type:

Invalid file associations could be the result of underlying issues within your Windows PC. It is highly recommended to scan your PC for invalid registry entries and identify any PC issues .

In general, the DB file extension references a generic database file used for the storage of various types of information using a structured format. This file may be generated by a number of varying database applications or can be imported into different database software. More specifically, the DB file extension format is the default used by the Borland Paradox database. This program is considered as an RDBMS (Relational Database Management System) that was originally developed by Borland until it was acquired by Corel Corporation. This is perhaps one of the oldest commercially available database applications in the market having been launched during the DOS era by the Ansa Software in 1985. Borland officially released the Windows-based version of this application in 1992. The DB file extension supported the highly successful database application which was subsequently retooled under the Borland C++ windowing toolkit and eventually utilized a different extended memory access scheme. This program was distinguished from the xBase clones of dBase by its visual Query By Example functionality which was supported by its AI engine.

The DB file extension supported Paradox for Windows was an entirely different software altogether developed by a new team of programmers. Even if majority of the feature sets inherent under the DOS environment were retained, a major difference lied on the compatibility with PAL to ObjectPAL including its shift to the GUI (Graphical User Interface) design for the Forms and Reports feature. The use of PAL, although controversial, was forced primarily due to the lack of acceptable equivalent for the keystroke recording operation in Windows. The DB file extension supported the object-based programming language founded on the Hypercard ideas as replacement for the keystroke recording. The application also capitalized on the functionality of the right button of the mouse pointing device. By using the right-click feature under the Forms and Reports window, the Properties is displayed. This functionality is based on the implementation of Xerox Alto and Smalltalk which are now a standard for all Windows-based applications. Historically, the DB file extension supported Paradox competed for market share with dBASE until both companies were eventually acquired by different corporations.
