WindowBase was a database management system created by Software Products International (SPI) as the successor to its manager for MS-DOS, Open Access. Introduced in 1991,[1] it was launched in Europe in 1992.[2] It cost $495 ($695 with the SDK for C).[2]

The program incorporated functionalities such as a SDK for C and C++ and support for SQL. The interface offered, among other features: personalization of menus; tools for creating graphical representations of its output; predefined groups of screen and print formats; and context sensitive help. Data could be exported to or imported from the dBase format, Btrieve format, or SPI's own Open Access format. In monoposition,[clarification needed] it was compatible with the Microsoft SQL Server.
