  1. Illinois Institute of Technology CS487 Software Engineering Midterm Review David Lash

  2. What it covers • ~2 hours long • A mixture of concepts and problem solving • Covers material from the beginning of the course through this 7/3/01

  3. What it covers • 1. What is SE Softw Lifecycle models • Various models (waterfall, prototype, incremental, sprial evolutionary concurrent) • What are the advantages of … • What are the weaknesses … • Which model would you use if ... • 2. Requirements -> Requirements process, FAST, QFD, partitioning, • What is QFD? What is FAST

  4. What it covers • 3. Requirements II - several modeling techniques, use case, system context diagrams, Partitioning • Data Modeling - Entity-Relation - Data objects and their relationships • Information flow diagram - Data flow diagrams - how data transforms in system- how functions transform data • Control Specifications - State diagrams - how system behaves as result of external events . • Test example list HW

  5. What it covers • Consider the problem of designing the software system for an automatic teller machine (ATM). • The user puts his or her card into a slot, enters a four-digit PIN (personal identification number), and can then perform the following operations on different bank accounts: d • deposit any amount, • withdraw funds (the account may not be overdrawn), • determine account balance, or • transfer funds between two accounts. • Design the ATM system using a transaction-oriented analysis. Draw a data flow diagram (Level-0 and Level-1). Note: in this question you do not have to specify (e.g., using pseudo-code) processes, data flows, external entities, stores and modules

  6. What it covers

  7. What it covers

  8. What it covers • 4. More Requirements - Decision tables, • Like HW • 5. Design concepts - abstraction, cntrl hierarchy, struct programming, info hiding, coupling, cohesion • What is the problem with content coupling. • Suppose Module X and module Y both access the same global structure, what type of coupling is it? • List all types of module cohesion. For each type of module cohesion provide its description and an example of a module exhibiting that kind of cohesion.

  9. What it covers • 6. Architectural concepts - various types of architecture, DF oriented design • For a DF diagram with a transform flow, translate into one with none. • (transform and transaction flow) • Go to structure Chart. • 7. Low level design concepts - pseudo code, Struct programming • What is SP, what programming constructs does it require? • 8. OO software concepts - • What is the difference between inheritance and polymophism?
