Chapter 2-1: Data Dictionary Overview

Files

The APPX dictionary establishes the logical structure of your database. The physical structure of a database and how it is stored on disk varies from system to system.

The data dictionary’s file formats represent permanent data storage in an APPX application. Files consist of a collection of related records, each containing one or more fields, the most elemental data storage structures of an application.

APPX supports one-record, consecutive, and indexed organization. You can designate either fixed- or variable-length records and, optionally, whether you want a file stored on disk or in memory.
