Abstract: An apparatus of managing data according to the present invention includes a query processor, a page monitor, a page layout manager and a data storage manager. The query processor processes a user query. At the time of processing the user query, the page monitor collects accessed column information and selectivity information of accessed columns from the query processor and collects access page information from a data storage manager to create page monitoring information. The page layout manager creates page column group information by grouping columns adjacent to each other for each page at a predetermined time interval based on the page monitoring information. The data storage manager stores data in a main memory by reconfiguring a page based on the page column group information for a candidate page of which an access frequency is greater than a predetermined access frequency based on the page monitoring information.

Abstract: Disclosed is a technology for data storage management in a database system, and more particularly, a data storage technology for a mixed OLAP/OLTP workload. A column group selection apparatus for efficiently storing data in a mixed workload processing environment includes a query processor configured to create column access information about queries that are input, a page monitoring module configured to create page-specific query pattern information using information about a page at which each of the input queries accesses and the column access information, a page layout manager configured to create page column group information in which a column group to be used to form each page is selected by applying a tree-based algorithm for selecting a column group to the page-specific query pattern information, and a data storage manager configured to create and store pages in units of column groups based on the page column group information.
