Process Driven and Data Driver Approach Difference

Differentiate between PROCESS DRIVEN AND DATA DRIVEN APPROACH

Process Driven Approach
If several entities are always created together and deleted together then this is a strong indication that they should be grouped into a single logical file. For example A customer PO is a single group of data from a user business perspective. It consists of a header and items information. From a business perspective, an order cannot be created unless it has at least one item And if the order is deleted both the order header and items are deleted. However the Header and the items may have independent maintenance transactions.
Data Driven Approach
Entity Independence: an entity has significance to the business in and of itself without Presence of other entity this is a logical file. Entity Dependence: an entity is not meaningful, has no significance to the business in without the presence of other entity this is an RET.
