ABSTRACT:
The present invention provides a method and system for a query on dynamic properties of objects. The method includes: obtaining a query; determining that the query pertains to at least one mapped dynamic property; obtaining mapping data for the at least one mapped dynamic property; and translating the query for the at least one mapped dynamic property according to the mapping data to run against a database. The method uses the stored mapping data of the dynamic property to translate the query on the mapped dynamic property such that it may be run against the database. In this manner, queries on mapped dynamic properties are performed through pushdown rather than in object space. This increases the efficiency of the queries.
