摘要

A method, system and article of manufacture for managing execution of queries against heterogeneous data structures are disclosed. One embodiment provides a method of processing a database query. The method comprises receiving, from a requesting entity, an abstract query of data contained in a database and an external data source. From the abstract query, an executable query is generated that is configured to access the database and a temporary data structure generated using data from the external data source. From the executable query, a data request configured to identify the data from the external data source to be included with the temporary data structure is generated. Then, the temporary data structure is generated using the data request. The executable query is executed against the database and the temporary data structure to obtain a result set. The obtained result set is returned to the requesting entity.
