Database Object Management
You can also use the Database Object Manager to create new database objects-namely views and possibly tables. In most cases, you will be viewing or manipulating data in tables that already exist. For information on creating database objects, see the Visual DBA online help.
You can define a view, or virtual table, to limit access to specific columns in a table. For more information, see the "Creating a View" topic under Managing Tables and Views in the Visual DBA online help
