Data processing system for data base management of matrix type data

摘要

A data base management system of a data processing system handles a hierarchical structure model. Matrix type data, considered as having different hierarchical structure in accordance with the application, is effectively handled by storing in the form of one- dimensional data in a file device and making up the desired hierarchical structure when used. This is accomplished by providing first order address information and designating a scheme code which defines the desired hierarchical structure when the data is utilized by a user.
