A relational database management (DBMS) and application development system for Windows from Corel. It includes the PAL programming language for writing complex business applications. When Paradox was originally released under DOS, it was noted for its visual query by example method, which made asking questions much easier than comparable products of the time. Originally developed by Ansa Software, it was later acquired by Borland and then Corel. The product was named Corel Paradox for a while, then offered as part of Corel's WordPerfect Office suites.
An Early Paradox Query
In the mid-1980s, Paradox was the first DBMS on a PC that made linking tables easier. The ability to associate relationships by typing sample words was a breakthrough for that time. The Customer No. and Part No. fields are linked by pressing a function key and typing in the common words "ABC" and "XYZ. Any words suffice as long as they are the same.
