APPLICATION ARCHITECTURE AND MODELING

1. Define an information system’s architecture in terms of KNOWLEDGE, PROCESSES, and COMMUNICATION—the building blocks of all information systems. Consistent with modern trends, these building blocks will be distributed across a network.
2. Differentiate between logical and physical data flow diagrams, and explain how physical data flow diagrams are used to model an information system’s architecture.
3. Describe both centralized and distributed computing alternatives for information system design, including various client/server and Internet-based computing options.
4. Describe database and data distribution alternatives for information system design.
5. Describe user and system interface alternatives for information system design.
6. Describe various software development environments for information system design.
7. Describe strategies for developing or determining the architecture of an information system.
8. Draw physical data flow diagrams for an information system’s architecture and processes.
