DATA STRUCTURE MANAGING DEVICE, DATA STRUCTURE MANAGING SYSTEM, DATA STRUCTURE MANAGING METHOD, AND RECORDED MEDIUM WHERE DATA STRUCTURE MANAGING PROGRAM IS STORED

摘要

In the case where there is a plurality of data structures deployed in one or a plurality of storage units, while reducing communication traffic, easy yet efficient maintenance and management of a plurality of data structures is implemented. A data structure management apparatus according to the present invention is a data structure management apparatus (10), which manages a plurality of mutually equal data structures stored in one or a plurality of storage units, comprising a data structure storage unit (20), which stores an arbitrary first data structure; a data structure modification unit (105), which modifies the first data structure; a modified data extraction unit (107), which extracts only the data necessary for making the first data structure on the modification source side and a second data structure on the modification target side be equal, from the modified data in the first data structure by the data structure modification unit; and a modified data transmission unit (111), which outputs the extracted, modified data so as to reflect onto the second data structure.
