ODABA

ODABA is a Terminology-Oriented Database Management System (TODBMS) based on standards for object-oriented databases (ODMG 2003). In contrast to other databases that are focused on big data processing, ODABA stands for smart data processing, i.e. it is intended to be used for complex problems and complex data structures in combination with complex processing rules.Besides requirements for object-oriented databases, which belong to the P2 database family (see "Unified Database Theory"), ODABA also supports several P3 database features (hierarchical set relations). Claiming to be a P3 database, ODABA can be considered as high level intelligent database, which provides a lot of support for application developers and database designers. ODABA does support views, but not yet the complete P3 database family requirements. Full P3 support including aggregation schema support is planned for ODABA version 15 in 2017. In order to support complex schema development, application design, programing and software and database maintenance, ODABA provides a family of rapid application development tools for documentation, design and implementation. With ODABA Script Interface (OSI), ODABA provides a powerful object-oriented script language, which allows traversing along database instances like accessing hierarchical structures in memory. Syntactical similarities with C++/JAVA allow understanding and learning OSI easily. The combination of weak-typed collection and virtual functions (function overload) offer a new dimension of flexible implementation. Besides simple database applications, OSI may also be used in order to implement event handlers (triggers) for database and GUI (application) events. Thus, OSI becomes a universal implementation language, which may be used in all implementation areas.The latest version of the ODABA has been released on Saturday, December 31th, 2016. With ODABA 14.1.0 support for database views has been improved by supporting a built-in statistic object for higher level aggregation. Features for accessing external data sources (files and directories) have been extended. The complete list of bugs fixed is available in change and release logs or in notifications delivered with ODABA development databases. ODABA can be downloaded for free and is licensed as GPL software.

Whats new in this version:

With new version ODABA 14.1 support for database views has been provided. It includes extended view definitions in database schema and ODL, support for statistic object for hierarchical aggregation. Several minor improvements have been made. OSI debugging tools have been improved and several bugs have been fixed.
