Definition: Berkeley DB

(Berkeley DataBase) An open source database system that uses "key-value" pairs to create indexes to tables and other data structures (see key-value pair). For example, a record could hold a key (account number) and its value (row number), although a value can be any data structure including text, an image or an audio or video stream up to 4GB long. Unlike relational databases, Berkeley DB does not support SQL queries. All queries and data analyses must be performed by the application through the Berkeley DB programming interface (API).
