Berkeley DB is written in [[C (programming language)|C]] with API bindings for many other [[programming language]]s. 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]],<ref>[http://doc.gnu-darwin.org/intro/dbisnot.html Berkeley DB Reference Guide: What is Berkeley DB not?]. Doc.gnu-darwin.org (2001-05-31). Retrieved on 2013-09-18.</ref> although it has database features including [[database transaction]]s, [[multiversion concurrency control]] and [[write-ahead logging]]. BDB runs on a wide variety of [[operating system]]s, including most [[Unix-like]] and [[Microsoft Windows|Windows]] systems, and [[real-time operating system]]s. BDB was commercially supported and developed by [[Sleepycat Software]] from 1996 to 2006. Sleepycat Software was acquired by [[Oracle Corporation]] in February 2006, who continued to develop and sell the C Berkeley DB library.

After 4.3BSD (1986), the BSD developers attempted to remove or replace all code originating in the original [[AT&T Corporation|AT&T]] Unix from which BSD was derived. In doing so, they needed to rewrite the Unix database package.<ref name="freenix">{{cite conference |last1=Olson |first1=Michael A. |last2=Bostic |first2=Keith |last3=Seltzer |first3=Margo |title=Berkeley DB |book-title=Proc.

That request led to the creation of [[Sleepycat Software]]. This company was acquired by [[Oracle Corporation]] in February 2006. Berkeley DB 1.x releases focused on managing key/value data storage and are referred to as "Data Store" (DS). The 2.x releases added a locking system enabling concurrent access to data. This is what is known as "Concurrent Data Store" (CDS). The 3.x releases added a logging system for transactions and recovery, called "Transactional Data Store" (TDS). The 4.x releases added the ability to replicate log records and create a distributed highly available single-master multi-replica database. This is called the "High Availability" (HA) feature set. Berkeley DB's evolution has sometimes led to minor API changes or log format changes, but very rarely have database formats changed. Berkeley DB HA supports online upgrades from one version to the next by maintaining the ability to read and apply the prior release's log records.

Berkeley DB puts no constraints on the record's data. The record and its key can both be up to four gigabytes long. Berkeley DB supports database features such as [[ACID]] [[Database transaction|transactions]], fine-grained [[Lock (computer science)|locking]], hot [[backup]]s and [[replication (computer science)|replication]]. ==Oracle Corporation use of name "Berkeley DB"== The name "Berkeley DB" is used by Oracle Corporation for three different products, only one of which is BDB:<ref>{{cite web| url = https://www.oracle.com/database/technologies/related/berkeleydb-downloads.html| title = Oracle Berkeley DB Downloads: Latest Production Releases}}</ref> # Berkeley DB, the C database library that is the subject of this article # Berkeley DB Java Edition,<ref>{{Cite web|title=Oracle Berkeley DB Java Edition|url=https://www.oracle.com/database/berkeley-db/java-edition.html|url-status=live|archive-url=https://web.archive.org/web/20170711100315/https://www.oracle.com/database/berkeley-db/java-edition.html |archive-date=2017-07-11 }}</ref> a pure Java library whose design is modelled after the C library but is otherwise unrelated # Berkeley DB XML,<ref>{{Cite web|title=Berkeley DB XML|url=https://www.oracle.com/database/berkeley-db/xml.html|url-status=live|archive-url=https://web.archive.org/web/20160718014819/https://www.oracle.com/database/berkeley-db/xml.html |archive-date=2016-07-18 }}</ref> a C++ program that supports [[XQuery]], and which includes a legacy version of the C database library ==Open-source programs still using Berkeley DB== BDB was once very widespread, but usage dropped steeply from 2013 (see [[#Licensing|licensing section]]).

Since BDB is a library, any application linking to it must be under an AGPL-compatible license. Many open source applications and all closed source applications would need to be relicensed to become AGPL-compatible, which was not acceptable to many developers and open source operating systems. By 2013 there were many alternatives to BDB, and [[Debian|Debian Linux]] was typical in their decision to completely phase out Berkeley DB, with a preference for the [[Lightning Memory-Mapped Database]] (LMDB).<ref>{{cite mailing list | url=https://lists.debian.org/debian-devel/2014/06/msg00338.html | title=New project goal: Get rid of Berkeley DB (post jessie) | mailing-list=debian-devel
