CA 2E Data Model Objects

CA 2E objects are not i OS objects. A CA 2E object exists only within a design model.CA 2E data model objects are classified into different types: files, fields, conditions, and relations.

CA 2E objects are interrelated in a data model design as described below:

• A file can reference either another file or a field through a relation.
• Conditions are attached to fields to specify the values that a field may take.

CA 2E objects are referred to by an object name.CA 2E object names must be unique. Specifically:

• A file name must be unique within the entire model.
• A condition name must be unique within the based-on field.
• A field name must be unique within the design model.

CA 2E makes no distinction between upper and lowercase characters in an object name. You can specify an object name in different ways and CA 2E will treat them as being the same. For example:

• Order code
• ORDER CODE
• Order Code
• ORDer coDE
