ObjectDatabase++

ObjectDatabase++ (ODBPP) is an embeddable object-oriented database designed for server applications that require minimal external maintenance. It is written in C++ as a real-time ISAM level database with the ability to auto recover from system crashes while maintaining database integrity. Its unique transaction process allows for maintenance of both the indexes and tables, preventing double allocation of index entries that could prohibit rollback of transactions.

Features of ODBPP include: full multi-process and multi-thread transaction control, auto real-time database recovery, hierarchical object data design, native code and script access, static hash index on object IDs, numerous supported index methods including full-text and biometric pattern matching.
