MetaMatrix introduces an XA compliant transaction server in addition to the MetaMatrix Server and MetaBase metadata repository. The MetaMatrix System has the capability to Create, Read, Update, and Delete data entities. This enables customers to treat a MetaMatrix Server spanning multiple physical data sources as a real database, with not only read capability but also write-back capability.

The Create, Read, Update, and Delete functionality also provides support for transactions and updates across multiple disparate data sources. Transactions are a logical unit of work that either modifies some state, performs a set of operations, or both. An individual transaction may involve multiple data and logical operations, but these operations always occur as an indivisible atomic unit, or they do not occur at all. With the addition of the XA transaction server, MetaMatrix is able to participate in distributed transactions initiated by another system. As an XA compliant system, the MetaMatrix Server will appear as an XA resource to the initiating system.
