Perst 4.0 from McObjectPresented as the latest upgrade of the open source, object-oriented, embedded database for Java and .NET, Perst 4.0 from McObject expands Perst’s usefulness in a broad range of applications by enabling it to add persistence to any object—including objects created by other programs, those for which source code is unavailable, and even objects created in different programming languages. For Perst Lite (the Java ME edition of Perst), version 4.0 adds seamless integration with the popular EclipseME integrated development environment, as well as improved handling of memory and storage.
