Released Metastorage generator

2002-12-05T16:11:44Z

Metastorage is an application that is capable of generating persistence layer APIs. It takes a component definition defined in the Component Persistence Markup Language (CPML), a XML based format, and generates classes and storage schemas in a given target programming language. Using CPML, developers can focus their efforts on the modeling of data structures that hold the information and the relationships between the entities that their applications deal with. Metastorage takes care of generating all the necessary code to store and retrieve such data structures from persistent storage containers like relational databases.
