We have installed APEX and the database objects, now we have to create a workspace that will hold our applications. A workspace is linked to one or more schemas in the database. Workspaces can contain zero or more applications. An application in a workspace can access all the objects of the workspace schemas. The following diagram explains the relation between workspaces and applications:

Relationship between workspaces and applications

If security issues are expected, it is possible to create a dedicated empty schema for the workspace and grant access to only the database objects that are needed for that schema. Applications in that workspace can only access the objects that have been granted to the schema.

When we want to create a workspace we have to log in to the APEX Administration Services. In APEX there are two special workspaces. Internal as mentioned before is, as the name implies, the internal workspace used by APEX itself. There is also another workspace called com.oracle.apex.repository, which is used for themes.

Once logged in to the Internal workspace, we see the screen shown in the following screenshot:

Creating a workspace

We have two possible ways to create a workspace: directly by using the button or indirectly through the Manage Workspaces option, where we have to click on Create Workspace. After filling in the details in the wizard, the workspace will be created.
