DISQLite3: Feature Chart
DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).
DISQLite3 Personal is free to use for personal, educational, and non-commercial use. It is fully functional without restrictions. Compared with DISQLite3 Pro it lacks some advanced functionality and may stay a few versions behind.
DISQLite3 Pro is required for commercial software. It is fully compatible with DISQLite3 Personal – upgrading just needs a simple recompile. It includes all SQLite3 functionality and is regularly updated with latest SQLite developments.
