Integration of a non-relational query language with a relational data store

摘要

A system and/or methodology that employs a non-relational (e.g., XML (extensible markup language)) query language to access stored procedures employed in connection with relational (e.g., SQL (structured query language)) database management systems is provided. Stored procedures in SQL enable the predetermination of queries that can be executed against the relational database. The invention bridges the gap between non-relational query languages and relational data stores. In other words, the invention enables the integration of non-relational query languages with relational data stores. The invention can define a view of the relational data in the current data model, convert data from relational to non-relational format and provide a mechanism in which a stored procedure can be referenced from the non-relational query language, using, for example, a function.
