Cego is an open source implementation of a relational and transactional database system using an object oriented software design.

Cego supports SQL query requests using all common programming interfaces (C, C++, Perl-DBD, Java). The system architecture is multi-threaded based on POSIX threads and is designed for high end performance and availability. For high availability requirements, Cego supports a distributed database shadowing feature.

For a detailed description of the database, please see the online Users Guide See the Change Log for a history of changes, which has been done for cego and friend packages.
