Base Claim:
1. A method for processing a query for transmission from a client computing system to an object-relational database server, comprising: receiving the query at the client computing system; parsing the query to determine which object-relational structures the query is attempting to access; determining, from data dictionary information loaded from the object-relational database server and cached locally on the client computing system, if the object-relational structures the query is attempting to access exist in the object-relational database server; if the object-relational structures do not exist on the object-relational database server, indicating an error condition; and if the object-relational structures exist on the object-relational database server, sending the query to the object-relational database server.

Claim 15:
15. The method of claim 1, wherein determining if the object-relational structures the query is attempting to access exist in the object-relational database server further comprises: determining that the query includes a reference to an attribute of an object from a table; and using the data dictionary information to expand a type for the object to verify that the attribute exists in the object.
