Abstract

PURPOSE: To retrive data only by inputting short retrieval information even in case of a large data volume, by forming data with a tree structure and storing information, which indicates inter-data relations, in a storage unit in a form of table.
CONSTITUTION: Retrieval information 11 inputted in a form of parallel code by retrieval information input device 1 is transferred to code conversion circuit 10 in a form of code, and alphabetic information out of retrieval information is converted to control signals and is transferred to timing signal output circuit 30. Data storage circuit 20 refers to the retrieval table in circuit 20 on a basis of control signals from circuit 30 and accesses the data storage part in circuit 20 on a basis of this table and outputs pertinent data to the next-stage output device as 2011.
