I see quite a bit of requests around Domains, but I am unsure if my requirement is covered in them, as many of them relate to Class modelling.
In my experience with tools such as Erwin, you have the ability to define a Domain, which is not really a custom / user defined datatype, but rather a user defined pattern, or implementation of a data type.
So for example, if I decide that all attributes of "Primary Key" database, would have the following characteristics:
- a primary key,
- not null,
- auto generated
- integer data type
Another example, I could model a "description data type", which would be:
Etc. When designing large, complex data models, this has quite a large impact on productivity, especially if one has to apply a change to a large model.
