Title:
PRICE RETRIEVING FILE AND CONTROLLER FOR THE SAME
Document Type and Number:
Japanese Patent JPH05189289
Kind Code:
A
Abstract:
PURPOSE: To reduce the queuing time of succeeding processing when plural pieces of the processing are generated continuously, and to suppress file redundancy low.
CONSTITUTION: A PLU file 1 consists of blocks 2-1 to 2-N divided by a prescribed unit set beforehand. Block keys 20-1 to 20-N and PLU records 21-1 to 21-N corresponding to these are stored in each block 2-1 to 2-N. When the block key is inputted to the PLU file 1, the target block corresponding to the corresponding block key among the blocks 2-1 to 2-N is retrieved by binary research. When a PLU key is inputted to the PLU file 1, the target PLU record corresponding to the PLU key is retrieved in the target block by the binary research.
