You are developing a network for a company’s online transaction processing (OLTP) application (e.g., a retail sales network). Its current system is a mainframe that has several terminals connected to it, either directly or through a terminal server, as in Figure 4.A. It is moving to a hierarchical client–server network, where there will be multiple regional database servers, each acting in a client–server fashion and updating each other’s regions via a database manager, as in Figure 4.B.

1. Show the probable data sources and sinks for both environments.
2. How does migrating from the mainframe environment to the hierarchical client–server environment modify the traffic flows in the network?
3.  In what ways does the network environment improve the traffic flows?
4.  What are some of the potential trade-offs between the two environments—for example, in security, management, and performance?
