  • Patent number: 10372563
    Abstract: Disclosed are an analyzing system for managing an information storage table and a control method thereof. That is, each of the physical basic regions, which are units of hashing an information storage position, is divided into a plurality of physical sub regions having same size. Then, a combination of virtual basic regions which satisfy a predetermined target value is checked from all configurable combinations and a hash value related with the combination of the virtual basic regions which satisfies the checked target value is stored in a predetermined region of a memory. Therefore, even though an information storage space required for every unit region is overloaded, when there is an extra information storage space in another region, the information storage space having an extra space is used to maximize efficiency of the information storage space.

  • Patent number: 7162490
    Abstract: A method of processing a dynamic database in a distributed processing system based on CORBA platform includes calling a generic method in a server, detecting data by the called generic method, storing the detected data, and returning the detected data to a client, in the distributed processing system. The detected data is initially stored in a local memory of the database. The generic method then creates a dynamic storage area in the database for the data based on the number of data units that were detected, and based on the size of the detected data unit. In this manner, there is no need to pre-define the structure of the storage area before performing the query.
