Answer to Question 1
Logical integration refers to how users get access to data across functional areas. For example, sales people need to get approval for customer credit from the credit managers in the finance department so this would be logical integration in the order processing process. Underneath the logical integration, the required applications and databases need to be connected physically. For example, customer data in a mainframe system may have to be linked up with credit management applications running on a Client/Server network. This would be an example of physical systems integration.
