Now, look at our suggested answers:

1. What is the primary entity type that is the focus of the process UPDATE GOLFER?

   GOLFER

2. What is the entity action to be taken on this entity type?

   UPDATE

3. Walking the neighborhood, are there any other entity types or actions required of this process?

   If we are going to update the GOLFER, the Toolset requires us to first establish currency on GOLFER. There are two ways to establish currency:

   • Create an occurrence of the thing that you want to establish currency with
   • Read an existing occurrence of the thing

   In this case, we want to update an existing golfer, so we want to read an existing occurrence of golfer. Then, walking the neighborhood, we see that golfer has an optional relationship to SCORING RECORD. The scoring record has no bearing on this process. So there are no other actions or entity types required.

4. Sequence the actions.

   We have identified two actions, an update, and a read. Prior to updating the golfer, we must first establish currency. Currency is established by reading the golfer. Therefore, the correct sequence is:

   a. Read the golfer

   b. Update the golfer

5. Determine the selection criteria.

   In most cases, you will read the desired object by its identifier, or by the identifier of some related object. This usually begs the question, however, what if all we have is their name? In Design, you make provisions for looking up things by other attributes or relationships, and then once identified, you would call the update process with their unique identifier.

Now we can add the process logic to the UPDATE GOLFER process action diagram.
