ABSTRACT:
A method for record searching in a database within a computer system are disclosed. The computer system includes a main processor, a main memory, and a peripheral storage device having a secondary processor. In accordance with the method of the present invention, a command block specifying a search string for record searching in at least one database table of the database is prepared. Subsequently, the command block is issued from the main processor to the secondary processor within the peripheral storage device of the computer system. The secondary processor within the peripheral storage device is then utilized to read the database table(s) into a memory within the peripheral storage device, in response to a receipt of the command block. The search string in the command block is compared to each record of the database table(s) within the memory of the peripheral storage device to identify all the records therein which contain the search string. Finally, all identified records which contain the search string are moved from the memory of the peripheral storage device to the main memory within the computer system, such that database record searching may be performed in a more efficient manner.
