Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A computing device for processing a query related to a plurality of partitions included in a plurality of tables having different partition information, the computing device comprising:
at least one processor; and
a storage unit,
wherein the at least one processor is configured to:
acquire, by the at least one processor, the plurality of partitions for processing the query,
acquire, by the at least one processor, global partition indexes for encompassing the acquired partitions and acquire local partition indexes corresponding to the acquired partitions, respectively, and
process, by the at least one processor, the query at least partially based on the global partition indexes and the local partition indexes;

wherein the plurality of tables includes a first table and a second table, and
a first number of partitions included in the first table and a second number of partitions included in the second table are different from each other;
wherein a first range of the partitions included in the first table and a second range of the partitions included in the second table are different from each other;
wherein the global partition indexes are generated based on the ranges allocated to the acquired partitions, respectively; and
wherein the global partition indexes are generated so that the total number of the global partition indexes is reduced based on the ranges of the respective local partition indexes.
