Embedded Database Support

McObject provides a variety of support options, both to assist those who are new to its technology, and to enable experienced developers to gain more from the eXtremeDB in-memory embedded database system (IMDS) and Perst open source, object-oriented embedded database system.

This site offers several “self-serve” support options, including basic product information on the eXtremeDB technical specification and Perst technical specification pages. A more detailed picture is available from the User’s Manual and Reference Guide, available for free from the downloads section of this Web site.

In addition, our FAQ addresses many technical and conceptual questions about the eXtremeDB and Perst embedded databases, and is must-reading for anyone considering using the product.


Finally, our free Support and Discussion Forums allow you to post questions and benefit from other developers' experience using eXtremeDB and Perst.
