Projects

The project is the highest-level and largest object in the OWB workspace. Each project acts as the container for all objects in the data system that contains the sources and targets. The work you do on your data system is done within the context of a project. Projects store and organize related metadata definitions. You should include all the objects in a project that you think can or will share information. These definitions include data objects, mappings, and transformation operations. The definitions are organized into folders within the project. By creating multiple projects, you can organize the design and deployment of a large system.

You can create projects according to functional areas like Sales, HR, Customer Service, and so forth. Projects are organized in tree hierarchies with modules for specialized types of metadata and OWB objects. Multiple users can concurrently access an OWB project. Changes and updates are managed through a locking mechanism to ensure data integrity.

Projects contain these main structures, which are described in this section:

• Modules

• Folders

• Collections

To create a project

1. In the Project Navigator, right-click a project, such as MY_PROJECT, and select New.

   The Create Project dialog box is displayed.

2. Click Help for additional instructions.

Each OWB workspace has a default project called MY_PROJECT. You can rename MY_PROJECT, or you can delete it after you create other projects. However, a workspace must contain at least one project at all times.

Because projects are the main design component in OWB, some restrictions are enforced to prevent you from deleting them unintentionally. You cannot delete:

• The currently active or expanded project.

• The only project in a workspace.

To delete a project

1. In the Project Navigator, collapse the project that you want to delete. You cannot delete the project when it is expanded.

2. Select and expand any other project.

3. Highlight the project you want to delete and, from the Edit menu, select Delete.

   or

   Right-click the project and select Delete.

   The Warehouse Builder Warning dialog box provides the option of putting the project in the recycle bin.

4. Click OK to delete the project.
