Workspace

• Oracle Application Express enables a single database to host large numbers of users.

• Users work in a dedicated work area called a workspace.

• A workspace is a virtual private database that enables multiple users to work within the same Oracle

• A workspace is a virtual private database that enables multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private.
