Data Division
The logical and physical concepts that apply to the Data Division in any COBOL
program also apply to your database programs. The HP COBOL Reference
Manual presents the general formats for Data Division entries and clauses,
describes their basic elements, and lists rules of use. Information of special
interest to the database programmer will be found here.
The Data Division defines the data processed by your COBOL program in both
physical and logical terms. It also specifies whether the data is contained in files,
a database, or Oracle CDD/Repository, or is developed only for local use in your
program.
The Subschema Section specifies data contained in a database or Oracle
CDD/Repository. The Working-Storage and Linkage Sections contain data
description entries, which describe characteristics of data developed for use in
your program.
