The present invention relates to a system and methodology to facilitated data object persistence. An object schema is utilized to provide metadata for types in addition to what is provided by the type system for an underlying programming language. This metadata is then utilized by the system to translate data to and from user objects during a materialization or persistence process. The object schema provides information external to programming logic and type definitions. Consequently, the object schema can be deployed independent of an application thereby allowing the persistence storage of user objects to change without force the user to recompile and deploy application code.

System and method of providing and utilizing an object schema to facilitate mapping between disparate domains

The select list for the query is thus constructed such that it produces a result set having a predefined structure. Columns representing identifier properties of an entity are added to the select list. If the entity is an inheritance entity or a collection, then entities from a least derived entity to all descendants are identified and columns representing their identifiers are added to the select list and columns representing non-inherited properties for those entities are added. If the entity is not an inheritance entity or a collection, then columns representing properties of the entity are added to the select list.

Result set formatting and processing

Join expressions, expressed in terms of objects, are translated into a relational database join statement by generating a parse tree based on the join expression. The parse tree is traversed to build the relational database join statement.
