Project Release Information
Fixes and improvements in btrees.
Ordering and grouping was changed: the new introduced AVLTreeT base class is used to build up the ordering and grouping trees (requires lfc 1.4.0). Now any grouping and ordering queries can be performed in logarithmic order.
This release adds btree objects to CegoXPorter (tableset import and export).
This release adds btree+ index support. Using this index type increases index creation time and space consumption significantly.
A bugfix has been made for like predicates in combination with function calls (e.g.
select forename from kids k where gender = 'girl' and lower(forename) like '%nn%';). The QueryHelper did not analyze the condition correctly.
Cego implements a relational and transactional database system with support for the SQL query language. The current release contains the most common database features for basic table manipulation and data retrieval. Indexes, foreign keys, views, and stored procedures are also implemented. Future releases (2.0 and above) will support a multi-node database concept with log file shipping for an automatic database application failover.
