Berkeley DB ( BDB ) is a software library that provides a high-performance embedded database for key / value data.

, Berkeley DB is the most widely used database toolkit in the world, with hundreds of millions of deployed copies.

Berkeley DB is written in C with API bindings for C ++, PHP, Java, Perl, Python, Ruby, Tcl, Smalltalk, and most other programming languages.

Berkeley DB is not a relational database.

Berkeley DB is also used as the common name for three distinct products ; Oracle Berkeley DB, Berkeley DB Java Edition, and Berkeley DB XML.

Berkeley DB originated at the University of California, Berkeley as part of the transition ( 1986 to 1994 ) from 4. 3BSD to 4. 4BSD and of the effort to remove AT & T-encumbered code.

In 1996 Netscape requested that the authors of Berkeley DB improve and extend the library, then at version 1. 86, to suit Netscape's requirements for an LDAP server and for use in the Netscape browser.

This company was acquired by Oracle Corporation in February 2006, which continues to develop and sell Berkeley DB.

Since its initial release, Berkeley DB has gone through various versions.

# Berkeley DB Java Edition

Its design resembles that of Berkeley DB without replicating it exactly, and has a feature set that includes many of those found in the traditional Berkeley DB and others that are specific to the Java Edition.

Three APIs are available — a Direct Persistence Layer which is " Plain Old Java Objects " ( POJO ); one which is based on the Java Collections Framework ( an object persistence approach ); and one based on the traditional Berkeley DB API.

The Berkeley DB Java Edition High Availability option ( Replication ) is available.

Note that traditional Berkeley DB also supports a Java API, but it does so via JNI and thus requires an installed native library.

In 2000, Dan Hettena at UC Berkeley ported Nachos to Java as Nachos 5. 0j, in an effort to make Nachos more portable, more accessible to undergraduates, and less susceptible to subtle bugs in student code that had in earlier versions often dominated student project development time.

He designed and wrote Berkeley UNIX ; He was also involved in the development of the Solaris operating system, SPARC microprocessor architecture, and the Java programming language.

Sleepycat License ( sometimes referred to as Berkeley Database License or the Sleepycat Public License ) is an OSI-approved open source license used by Oracle Corporation for the Berkeley DB, Berkeley DB Java Edition and Berkeley DB XML embedded database products.

Stratus offers supported ports of Samba, OpenSSL, OpenSSH, GNU Privacy Guard, OpenLDAP, Berkeley DB, MySQL Community Server, Apache, IBM WebSphere MQ, and the community edition of Java.

He devoted himself to the study of British and Irish philosophers, especially George Berkeley, and published a Collected Edition of the Works of Bishop Berkeley with Annotations, etc.

The procedure is described in a series of papers from the early 1970s by Bruce Ames and his group at the University of California, Berkeley.

Arthur Robert Jensen ( born August 24, 1923 ) is a Professor Emeritus of educational psychology at the University of California, Berkeley.

Bell Laboratories ( also known as Bell Labs and formerly known as AT & T Bell Laboratories and Bell Telephone Laboratories ) is the research and development subsidiary of the French-owned Alcatel-Lucent in Berkeley Heights, New Jersey.

It is named after the city of Berkeley, California, the location of the University of California Radiation Laboratory where it was discovered in December 1949.

Thus the discovery report by the Berkeley group reads: " It is suggested that element 97 be given the name berkelium ( symbol Bk ) after the city of Berkeley in a manner similar to that used in naming its chemical homologue terbium ( atomic number 65 ) whose name was derived from the town of Ytterby, Sweden, where the rare earth minerals were first found.

Berkeley DB is redistributed under the Sleepycat Public License, which is an OSI-approved open source license as well as an FSF-approved free software licence.

There is third party support for PL / SQL in Berkeley DB via a commercial product named Metatranz StepSqlite.

The first is the traditional Berkeley DB, written in C. It contains several database implementations, including a B-Tree and one built around extendible hashing.

It is implemented as an additional layer on top of ( a legacy version of ) Berkeley DB and the Xerces library.

This license is a 2-clause BSD license with an additional copyleft clause similar to the GNU GPL version 2's Section 3, requiring source code of an application using Berkeley DB to be made available for a nominal fee.

Thus, the license depends on how a particular application that uses Berkeley DB is distributed to the public.

Fine grained (< 300A grain size, US4897360 ), post strain annealed pure polysilicon was advocated by Prof Henry Guckel ( U. Wisconsin ); while a larger grain, doped stress controlled polysilicon was advocated by the UC Berkeley group.

Orville Schell, dean of the UC Berkeley Graduate School of Journalism, said in 2005 that " It's hard to vouch for their quality because it's difficult to corroborate, but it's not something to be dismissed as pure propaganda.

The two most common systems are the classification adopted by the website AmphibiaWeb, University of California ( Berkeley ) and the classification by herpetologist Darrel Frost and the American Museum of Natural History, available as the online reference database Amphibian Species of the World.

Berkeley DB's evolution has sometimes led to minor API changes or log format changes, but very rarely have database formats changed.

Berkeley DB includes compatibility interfaces for some historic Unix database libraries: dbm, ndbm and hsearch ( a System V library for creating in-memory hash tables ).

Berkeley DB has an architecture notably simpler than that of other database systems like relational database management systems.

Despite having a simple architecture, Berkeley DB supports many advanced database features such as ACID transactions, fine-grained locking, hot backups and replication.

The Berkeley DB XML database specializes in the storage of XML documents, supporting XQuery via XQilla.

Berkeley DB provides the underlying storage and retrieval system of several LDAP servers, database systems, and many other proprietary and free / open source applications.

* RPM – The RPM Package Manager uses Berkeley DB to retain its internal database of packages installed on a system

While earlier versions of BIND offered no mechanism to store and retrieve zone data in anything other than flat text files, in 2007 BIND 9. 4 DLZ made available ( as a compile-time option ) zone storage in a variety of database formats including LDAP, Berkeley DB, PostgreSQL, MySQL, and ODBC.

In February 2006, Oracle Corporation acquired Sleepycat Software, makers of the Berkeley DB, a database engine providing the basis for another MySQL storage engine.

These include data base connection handling for various database systems ( MySQL, PostgreSQL, ODBC, Berkeley DB and others ), binding to the library CURL, PNG graphics, GTK + graphical user interface, sockets, regular expressions, thread support, data compression and CGI.

* OpenLDAP Version 2. 1, released in June 2002, included the transactional database backend ( based on Berkeley Database or BDB ), Simple Authentication and Security Layer ( SASL ) support, and Meta, Monitor, and Virtual experimental backends.

While SN is best known in the context of web development, the concept predates the web: Michael Stonebraker at the University of California, Berkeley used the term in a 1986 database paper.

Berkeley DB is a widely used and freely-licensed database software originally developed at the University of California, Berkeley for 4. 4BSD Unix, and developers from that project founded Sleepycat in 1996 to provide commercial support after a request by Netscape to provide new features in the database software.
