Upgrading to a New Release › Considerations When Upgrading CA Gen Components › Schema Release Levels

Schema Release Levels

The underlying structure of stored model information consists of objects, properties, and associations. The structure adhere to a rigorous set of rules that define:

• Objects that are allowed or that you can create
• Properties that are allowed or are required to describe those objects
• Associations that are allowed or are required to describe how those objects relate to one another

The objects, properties, and associations; and rules that govern how they interrelate, are named the schema release or metamodel, for a CA Gen software release. A schema of an encyclopedia is the highest model schema the Encyclopedia supports.

The DMAX table stores values for properties that apply to the entire encyclopedia, such as the encyclopedia name and ID. The highest schema release level on the DMAX table identifies the current version of the metamodel an Encyclopedia supports.

The DMDL tables stores values for properties that apply to an entire model, such as the model name. The MODEL_RELEASE in the DMDL table indicates the release level for each model.

The following table lists releases over the past several years, the schema release level for each release, and the introduction and retirement dates.

Current schema is the schema for the current release of CA Gen. Prior schema and second prior schema refer to schemas supported in the most recent releases of AllFusion Gen.

Note: For the schema designation for Current Schema, Prior Schema, and Second Prior Schema, see the Release Notes or the Toolset Help.

The same rules apply to each release according to the schema supported in the release. A statement about support for a particular schema applies to all releases that support the schema.
