In Sentences Version 3.0, the emphasis is on scalability. The internal structure of the Sentences database has been restructured and disk access methods have been enhanced to improve performance, scalability and robustness. Also, the CPU cycles and disk accesses needed for data retrieval and update operations have been reduced.

A single Sentences database may comprise multiple chapter files, and Sentences Version 3.0 can manage individual chapter files that contain in excess of 100,000,000 associations (occupying around 16 gigabytes), an improvement of around 50 times over Sentences Version 2.0.
