Defining a Database Using Non-SQL › Overview

Overview

This chapter provides information about Step 4, defining the logical components (schema, subschema) of the database.

Steps to Define a Database

To use non-SQL methods to define your database, follow these steps:

1. Design and size the database using information provided in the CA IDMS Database Design Guide document.
2. Define in the system dictionary the segments that represent the physical database. Include the segments in your DMCL, and generate, punch, and link edit the DMCL. For more information on the physical database, see Chapter 4, “Defining Segments, Files, and Areas".

   Note: You can defer this step until after you define the schema and subschema.

3. Allocate and format the operating system files as described in Chapter 17, "Allocating and Formatting Files”.

   Note: You can defer this step until after you define the schema and subschema.

4. Define a schema and one or more subschemas.
