Catalog Manager

A catalog is similar to a directory structure. A catalog contains the mart, libraries, models, and versions; it displays a hierarchical tree of the Mart. You create a catalog to create libraries and store models in it. You can also edit the description of each catalog entry by clicking the Edit button.

Some of the features in Catalog Manager are as following:

Libraries

Use libraries to group related models. Libraries add an extra level of security or isolate implementation differences, such as development and production environments. A library can be part of another library or can be present under the Mart.

Sorting

In a catalog, the libraries are sorted alphabetically, and the models within the libraries are also sorted alphabetically. Versions are sorted newest to oldest; Named Versions appear first, and then Delta Versions follow. The catalog entries sort in the following order: Libraries, Models, Templates, and Versions respectively.

Context Menu

The context menu appears when you select a catalog entry and right-click. You can use the context menu to cut, copy, paste, and delete a library, model, or template. You can also use the context menu to mark a Delta version and delete, hide, and unhide Named and Delta versions.

Hide and Unhide Versions

You can hide or unhide model versions according to your need. To hide a model version, select the version from the Catalog pane, and click Hide Version.

To unhide a model version, select the model of that version, click Unhide Version. From the Hidden versions dialog, select your version and click OK.

Maintain Multiple Versions

You have the option to maintain multiple versions of a model in Catalog Manager. Select a model from the catalog to view the Maintain multiple versions check box. Select the check box to maintain multiple versions of a model.

If you clear the Maintain multiple versions check box, then erwin® Data Modeler permanently deletes all the existing versions and it maintains only one version. erwin® Data Modeler stops creating a delta version for any incremental save.
