Berkeley DB 18.104.22.168.26 / Java Edition 6.4.9 / XML 6.0.18Description by Software Developer:
"Berkeley DB is a database engine that provides developers with fast, reliable, local persistence with zero administration. Berkeley DB is a library that links directly into your application.
Your application makes simple function calls, rather than sending messages to a remote server, eliminating the performance penalty of client-server architectures. Berkeley DB stores data in application native format, as simple key/value pairs, eliminating the need for translation or mapping. Berkeley DB eliminates the overhead of SQL query processing, enabling applications with predictable access patterns to run faster. Berkeley DB is the ideal choice for static queries over dynamic data, while traditional relational databases are well suited for dynamic queries over static data."
