Here’s a concise description of the difference between domain and data elements:
– Domain: Defines the allowable values and constraints for a specific attribute or field in a database. It sets the rules for what data can be stored in that field.
– Data Elements: Are the actual pieces of data stored within a database. They represent individual units of meaningful data, such as a person’s name, address, or phone number.
In essence, a domain specifies the rules and constraints for data stored in a field, while data elements are the specific instances of data that adhere to those rules and are stored in the database.
Domain is the central object for describing the technical characteristics of an attribute of an business objects. It describes the value range of the field.
Data element is used to describe the semantic definition of the table fields like description the field.
