Versant Corporation is an American-based software company building specialized NoSQL data management systems. Versant products are deployed in industries including: telecommunications, defense, life sciences, biomedical, transportation, finance, and online gaming. Versant was founded in Fremont, California (USA) in 1988. It is headquartered in Redwood City, California. Engineering teams are located in Hamburg, Germany and Redwood City. Versant offers NoSQL object database technologies, including, Versant JPA, Versant Object Database, FastObjects and the open source database db4o. == History == The company was founded by Kee Ong in August 1988 as "Object Sciences Corporation". Among the first employees were CEO Michael Seashols and kernel engineers Hong-Tai Chou, Stephen Au-Yeung, and C. P. Chou. Ong previously worked with the open-source relational database management system Ingres. Around this time object-oriented programming (OO) became popular, and the company used research done at the University of Wisconsin for a commercial database system to complement OO languages. In early 1990 the company was renamed “Versant Object Technology.” In April 1993 David Banks took over as CEO. On July 18, 1996 Versant had their initial public offering (IPO) on the NASDAQ stock exchange and traded under the symbol VSNT. The company raised $14.9 million from the IPO, and was based in Menlo Park, California at the time, but moved to Fremont, California in 1997.〔 In January 1998 Nick Ordon succeeded Banks as CEO. on July 15, 1998 the company was renamed again to Versant Corporation. In March 2004, Versant acquired Poet Software GmbH, a European-focused company targeting the Windows product market which had traded on the Frankfurt Stock Exchange. In 2005, Jochen Witte, president of Poet Software, took over as CEO of Versant Corporation. In August 2005, the common stock had a 1-for-10 reverse stock split. On December 1, 2008 Versant acquired the assets of the database software business of Servo Software, Inc. (formerly named db4objects, Inc.). It developed the open source embedded database technology db4o.〔〔 The original implementation of Versant was targeted at C, C++ and Smalltalk users. In 1995 Versant introduced support for the Java programming language and then in 2009 for C# and the .NET platform. In 2012 Versant introduced Versant JPA, a Java Persistence API 2.0 compliant interface for its object database, with a technical preview of an analytics product including Apache Hadoop support. In late 2012, after rejecting an offer by Unicom Systems Inc., Versant Corporation announced it was being acquired by Actian Corporation, the commercial developer of Ingres and the relational database, Vectorwise. The acquisition was promoted using the marketing term big data. It closed in December for an estimated $37 million. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Versant Corporation」の詳細全文を読む スポンサード リンク
