Part B

Question 1

List all the deliverables for each of the following stages:
Project planning, system design, coding, testing, and installation?

Question 2

List and describe the functional capabilities needed in an interface for effective entry and navigation. Which capabilities are most important and why? Will this be the same for all systems? Why or why not?

Part C

Question 1
Draw a context diagram for an Online Food Ordering System. Show online Food Ordering System as a single process. Show all the related entities and the data flows in and out of the system. Discribe two benefits of a Context Diagram in your own words.

Question 2
Draw an E-R diagram for the situation described below and place minimum and maximum cardinalities on the diagram relationships.

PlowMasters is a locally owned and operated snow removal business. PlowMasters provides residential and commercial snow removal for clients throughout a large metropolitan area. Typical services include driveway and walkway snow removal, as well as parking lot snow maintenance for larger commercial clients. PlowMasters' clientele has grown over the past several snow seasons. Recent heavy snowfall, coupled with a successful advertising campaign, has increased current demand even more, and this increase in demand is expected to continue. In order to provide faster, more efficient service, PlowMasters has hired your consulting company to design, develop, and implement a computer-based system.

Question 3
Study the following model in details.

What is the name of the above model type? Briefly describe the concept of this model type.
Based on the above model, draw its corresponding use case diagram that is used to create this diagram.

Question 4
List 3 testing types in systems development process and explain (for each testing type), in what stage of systems development it is used and why.

Question 5

List all types of systems Deployment strategies, and exsplain what deployment strategy is more suitable for what conditions.
