RELEX Group has published the report on the major modifications and updates made in all the basic versions of DBMS Linter during the 2nd quarter of 2011. Most modifications concern interaction with various platforms, operation of the DBMS kernel, SQL translator, utilities and interfaces, significantly improving the Linter subsystems.
DBMS kernel and SQL translator:
Alternative file format support (with bursting bitmaps) added in order not to move the pages when extending a file to improve reliability and performance.
Work with the channel queue optimized to improve multithread support in the future.
Compound external key building optimized to work with large-size tables of the external and primary/unique key.
Express JOIN query processing optimized to avoid drastic increase of pre-translated query size in case of multiple express JOIN.
Predicate calculation order optimized for queries with external references to quicken query processing.
For DevExpress support, it is now allowed to omit the COLUMN word in the ALTER TABLE ADD COLUMN syntax.
