Effective use of conventional, extended, and expanded memory – caching data tables and particularly indexes, which caused Paradox to execute tasks very quickly in contrast to the explicit skills required for xBase performance optimisation.An enhanced design and implementation of visual Query by Example that was supported by an AI engine for heuristic, dynamic query optimization.The features that distinguished Paradox/DOS were: Other notable competitors were Clarion, DataEase, R:Base, and DataFlex.

The New York Times described it as "among the first of an emerging generation of software making extensive use of artificial intelligence techniques," and noted that Paradox could read the competing Ashton Tate's dBase files. Paradox for DOS was a relational database management system originally written by Richard Schwartz and Robert Shostak, and released by their Belmont, California-based company Ansa Software in 1985. In mid 1991 Borland began the process to acquire Ashton-Tate and its competing dBase product line A Windows version was planned for release by Borland in 1992, but was delayed until January 1993, by which time Microsoft's Access for Windows was available.
