wsrep-enabled MySQL (previously MySQL/Galera cluster) can use wsrep replication providers, such as Galera, to form a cluster. wsrep API is an abstract replication interface that supports global transaction ID, true multi-master capability, conflict detection and resolution, and parallel applying and is transparent to triggers, stored procedures, and functions by replicating only final transaction results. Only the InnoDB storage engine and DDL commands are supported by this patch.
The OODBMS/DBMS ODABA is an terminology-oriented database management system (TODBMS) on a high conceptual level. This is an extension of the ODBMS concept according to ODMG 3. It provides a number of enhanced features based on natural language analysis. Beside the database kernel, a number of tools are provided for database design, documentation, and fast development. ODABA provides a powerful interface (C++, .NET) and an ODABA Script Interface (OSI), a C++/JAVA like scripting language, which provides easy access to the database.
