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. Products Other than Versant Object Database, Versant marketed two other commercial object-oriented database management systems (OODBMS), “Versant JPA,” and "Versant FastObjects". In addition, Versant offers the open-source database "db4o". Versant JPA is a JPA 2.0 compliant interface for its object database that includes a technical preview of an analytics platform including Hadoop support. It is available as a server and SDK for use with Windows and Linux operating systems. "Versant FastObjects" is a developer-friendly, object-oriented alternative to a relational database for .NET persistence. "db4o" is an open source embedded object database for Java and .NET. db4o is coded in Java and translated to C# by an open-source tool called Sharpen.
