Creating and Maintaining Object Subtypes

Oracle Life Sciences Data Hub includes a set of predefined object types, such as Tables, Programs, Report Sets, and Variables. Each of these object types has a predefined set of all possible operations that can be performed on objects of that type.

To allow you greater flexibility as you set up your security system, Oracle LSH bases object security on subtypes rather than the predefined object types. You can define different subtypes—for example, Clinical and Financial—for one or more object types and define different classification and security requirements for each subtype of the same object type. Object subtypes have the same predefined set of operations as their object type. Oracle LSH ships with one default subtype for each object type. If you do not wish to add the flexibility (and complexity) of subtypes to your design, you can use the predefined subtype only.

Defining additional subtypes is optional.

When a Definer creates an object, he or she must select an object subtype on which to base the object. The object has the classification and security requirements defined for the selected subtype.

When the Definer creates an object, the system checks the subtype of the parent object and, if a subtype with the same name is defined for the new object, uses that subtype for the new object. If the new object does not have a subtype with the same name, the system uses the predefined Default subtype. The Definer can change it as necessary.
