Abstract

The DF language (DF-COBOL and DF-PLI) developed by a new concept of data flow is a software for designing, developing, and maintaining business applications. It consists of the DF chart and DF language.

The DF chart is a powerful tool for describing briefly and appropriately the specifications of applications by using the technique of data flow and is the basis for DF language.

The DF language consists of elements which correspond to elements of the DF chart, so it is very easy to understand. It also generates automatically COBOL or PLI programs. Basic processing units prepared in the DF language are designed by using a complete modular concept, so the module units can be combined without any restriction, and the DF language has high generalities and low redundancies. The DF language can provide great improvements in application development productivity by using the technique of data flow.
