Enterprise Architecture Practice 8 - How to do EA Impact Analysis in Casewise 5

- Object Type Chains for OOB POLDAT
Object Type Chain existence had been explained in my previous article.
What kind of Object Types should be included into Object Type Chains? Since talking about Impact Analysis, both of POLDAT Object Type and User Defined Object Type should be included.
For OOB (Out of the Box) POLDAT, the Mathematics Model will be:

• POLAT
• OLDAT
• PROCESS <-> ENTITY, PROCESS <-> ATTRIBUTE
• ENTITY -> ATTRIBUTE, DOMAIN -> ATTRIBUTE

Note: Expanding Data from Entity to Entity, Data Usage (PROCESS <-> ENTITY, PROCESS <-> ATTRIBUTE), Attribute (ENTITY -> ATTRIBUTE, DOMAIN -> ATTRIBUTE) because of some of OOB associations existed in OOB already.
