Abstract: Disclosed are a system and a method for address translation for a flash memory device, and particularly, disclosed is a technology that is capable of efficiently performing address translation between a logical address provided to the outside of a flash memory and a physical address of an actual flash memory in managing the flash memory device. The system includes: a flash memory system writing a corresponding data page by allocating a physical address space when there is a request for writing a data page from storage clients, and performing address translation between a physical address and a logical address; and a logical address space formed between the flash memory system and the storage client to provide the logical address.

Abstract: Disclosed is an apparatus for in-memory data management includes a hybrid memory including a plurality of types of memories with different characteristics and a storage engine. The storage engine rearranges data among the plurality of memories by the unit of a page by monitoring workloads for data stored in the memories and reconfigures a page layout by the unit of the page based on a data access characteristic of an application for each of pages constituting each of the plurality of memories.

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.
