Patent ID: 7542984

Claim:
A data storage control system comprising: an expression-format changing device for changing applied data to data having a prescribed expression format; a storage device for storing data readably, wherein the storage device is a hard disk; a storage controller for accessing the storage device and reading data that has been stored in the storage device and writing the data having the prescribed expression format to the storage device in accordance with an applied read/write command, wherein the prescribed expression format has been changed by the expression-format changing device; a command execution device, to which an applied command is entered, for applying a read/write command to the storage controller in accordance with the applied command that is entered; a search device for accessing a database in accordance with an applied search command and searching data in the database; a table of expression formats stored in the expression-format changing device; a data generating device for generating a first data having a specific expression format from a second data that is substantially the same as the first data if a command is applied for extracting the first data having the specific expression format from the second data that has been stored in the storage device, and wherein the first data having the specific expression format which is non-existent and the second data that is substantially the same as the first data except for the specific expression format of the second data does exist, and wherein the expression-format changing device converts a format of the second data into each format of the formats listed in the table and wherein the expression-format changing device further converts a resolution of an image represented by image data, wherein the image data that is a part of the second data represents images of different sizes; and an interface for separably connecting the expression-format changing device, the storage device and the command execution device, wherein the interface comprises: a first interface for separably and directly, without via a network, connecting the search device and the command execution device; and a second interface for separably and directly, without via a network, connecting the expression-format changing device, the storage device, and the command execution device.
