A system includes definition of a remote data source, definition of a virtual function specifying executable job code, a return data format and a data location in the remote data source, reception of a structured language query including the virtual function as a data source, and, in response to the received query, instruction of the remote data source to execute the job code based on data in the data location and return data in the return data format.

Virtual function as query operator

A method, a system and a computer program product for maintaining a pre-computed result set are disclosed. A server coupled to a data source determines whether an object stored in the data source received an update. The server identifies at least one identifier associated with a pre-computed result set based on that determination. The pre-computed result set is computed based on the object. The server computes an updated pre-computed result set using the identifier by applying the received update to the pre-computed result set.

A system and method to generate an improved layout of a data grid in a database environment is provided. The data grid is a clustered in-memory database cache comprising one or more data fabrics, where each data fabric includes multiple in-memory database cache nodes. A data grid advisor capability can be used by application developers and database administrators to evaluate and design the data grid layout so as to optimize performance based on resource constraints and the needs of particular database applications.
