The data management apparatus includes a data management unit which manages key-value data stored in the SSD, and a file management unit which creates a file of a predetermined size in accordance with a request from the data management unit, and manages the created file. The file management unit creates a file having a size of an integral multiple of a block in the SSD, the data management unit requests file management unit to write the key-value data to be stored in the file, and manages a number of the effective key-value data in each file by invalidating pre-update data of the updated key-value data and the deleted key-value data, and requests the file management unit to delete the file no longer storing the effective key-value data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data management apparatus and method","description":"A data management apparatus for reducing the occurrence of garbage collection, and preventing deterioration in the performance of writing data into an SSD.
