Once the custom object is defined, the subscriber can perform the following tasks:
* Create custom fields
* Relate the custom object to other records
* Track events and tasks
* Build page layouts
* Create a custom tab for the custom object
* Analyze custom object data
* Create dashboards and reports
* Share custom tabs, custom apps, custom objects, and various other related components.
None of these tasks can be accomplished until the custom object has a definition.
