You are now nearing the end of the systems design phase for the TIMS system. The next step is to plan the system architecture that will include hardware, software, network support, and processing methods. One of your first tasks should be to visit the SCR data library and review the design of the current SCR network. you currently use a client/server design with an IBM server at your headquarters location. When you implement TIMS, you will need to select a network model, which can be based on your existing topology (which is a combination of several designs that evolved over the years), or propose a new design. Either way, please include a rough sketch and an explanation of your proposal. Please include recommendation for an overall client/server design, including the number of tiers. Also please comment on these issues: legacy data, Web-centricity, scalability, security, and batch processing that might be needed.
