Explanation: Whenever possible, you will want to use EDTs and EDTs should be created for each atomic entity in thesituation that your application is modeling.You should only create subtypes when they are needed. In other words, when you are creating an EDTthat extends another EDT, but you aren’t changing any of its properties, you probably do not need tocreate a new subtype.
