Abstract:

Implementation of the present disclosure relates to a method, system and computer program product for improvement of query execution. According to one embodiment of the present invention, there is provided a method. In the method a query on data organized in a first data structure is received first. And then based on at least one property associated with the query, a second data structure is selected from a plurality of candidate data structures, wherein a performance measure of the query on the data organized in the second data structure is better than the performance measure of the query on the data organized in the first data structure. And at last the query on the data organized in the second data structure is executed. In other implementations, a system and a computer program product are disclosed.
