Berkeley DB – family of embedded key-value database libraries

The Oracle Berkeley DB family of open source, embeddable databases provides developers with fast, reliable, local persistence with zero administration.

Berkeley DB is written in C with API bindings for C++, C#, PHP, Java, Perl, Python, Ruby, Tcl, Smalltalk, and most other programming languages. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. Berkeley DB is not a relational database.

Berkeley DB is also used as the common name for three separate products; Oracle Berkeley DB, Berkeley DB Java Edition, and Berkeley DB XML. All three are high performance, self-contained, software libraries which provide data storage services for applications, devices, and appliances.

Berkeley DB is used within a wide variety of open source and proprietary products for telecommunications, networking, storage, security, enterprise infrastructure, financial services, mobile applications, health care, smart metering and many other markets.
