Abstract
One embodiment of the present invention provides a method for constructing a query for an object-relational database. This method displays at least part of a schema for the object-relational database to a user in a graphical representation. Next, the method allows the user to perform graphical manipulations on the schema. The method then generates a query based upon the schema and the graphical manipulations, and this query is sent to the object-relational database. Another embodiment of the present invention provides a method for processing an object-relational query for transmission from a client to an object-relational database server. This method receives the query at the client, and parses the query to determine which object-relational structures the query is attempting to access. The method then determines from data dictionary information, loaded from the object-relational database server and cached locally on the client, if the object-relational structures the query is attempting to access exist in the object-relational database server. If they do not exist, the method indicates an error condition. Yet another embodiment of the present invention provides a method for display…
