Systems Analyst Designer Concepts and Techniques Assignment Tasks

Learning Outcomes

1 Have a comprehensive understanding of the role of the systems analyst/ designer, the context in which the systems development activity takes place and the professional standards that are applied  to the activity.

Based on the Wide World Tour Management System (attached as Appendix A), complete the following  tasks:

Part 1. Use Case Realisation for the ‘Record New Tour’ Use Case Analysis Class Diagram

a) In your own words, briefly describe what is meant by an Analysis Class Diagram, and how class diagrams can be useful in systems analysis and design

b) Draw an Analysis Class Diagram for the ‘Record New Tour’ Use Case, using the Use Case description given. This should include all required boundary, control and entity classes
with their associations and attributes. Your diagram should be drawn using the Enterprise Architect software and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those

a) In your own words, briefly describe what is modelled in a Communication Diagram, and how Communication Diagrams can be useful in systems analysis and design

b) Draw a Communication Diagram for the use case in your diagram that corresponds most closely to the use case ‘Record New Tour’, using the Use Case description given. This
should include all control, boundary and entity objects involved in the scenario and sufficient detail of the messages to show that the interaction is feasible and would meet the system requirements. Your diagram should be drawn using the Enterprise Architect software and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those

a) In your own words, briefly describe what is modelled in a Sequence Diagram, and how Sequence Diagrams can be useful in systems analysis and design

b) Draw a Sequence Diagram for the use case in your diagram that corresponds most closely to the use case ‘Record New Tour’. This should include all control, boundary and entity objects involved in the scenario and the sequence of interactions that take place in order to meet the system requirements. Your diagram should be drawn using the Enterprise Architect software, and copied and inserted as a picture into your document.

c) Write a brief summary of the decisions made whilst drawing the diagram, and your reasons for making those

Enterprise Architect is a CASE tool. In your own words and using examples, briefly describe what a CASE tool offers during analysis of the World-Wide Tours scenario, and what tasks the CASE tool supports. Give your own evaluation of how the role of an analyst/designer is  supported by a CASE tool. Discuss how UML modelling supports the analyst/designer
