ITC 44 Software Engineering

LIST OF ACTIVITIES

FIRST PRELIMINARY PERIOD

Exercise #1: Case Study Analysis (Group)

1) Refer to the Case Study of the Freeway Ford (Given by the Instructor).

2) Read and analyse the case study.

3) Form a group of 4 members.

4) Prepare a 5-minute presentation answering the following questions:

a) Enumerate and discuss the steps for systems approach in solving the problem.

b) Propose a system design for the software package SMART.

c) Describe, in systems terms, how SMART can benefit Freeway Ford.

Exercise #2: Software Planning using UML

This exercise is about UML Use Case Diagrams and Sequence Diagrams. Consider the following

Scenario. This relates to the activities of a Cable TV Provider:

In the offices of a Cables R Us, a cable TV provider, there is one helpdesk operator, who

answers calls from customers, and three engineers, who maintain the cable network system.

The company has many customers, who phone the helpdesk with enquiries.

Existing customers will phone the helpdesk to request repair to their system if it is faulty, or

to ask about upgrades (for instance to add more viewable channels. New customers often

phone in requesting installation. The helpdesk operator always offers an upgrade, even tonew customers, in case they would like to increase the channel selection they have already

agreed upon. As a result of the call from a customer, the helpdesk may book one of the

engineers. In this case, the helpdesk operator must consult the engineers schedule databaseand book an appointment. Installations for customers are always either upgrades or new

installations. Each engineer records when he/she is available on the schedule database. All

the engineers who maintain the network do installations or repairs.

(a) From the first paragraph in the above scenario, draw a simple Overview Use CaseDiagram, using the appropriate syntax. Ensure that you include an Answer Calls use

case, referring to the responsibility of the helpdesk.(b) Using the further information in the second paragraph, in addition to that provided in the

first paragraph, draw a Detail Use Case Diagram, using the appropriate syntax. You must

indicate values clearly or provide a paragraph explaining your assumptions. You shouldconsider the point of whether the database should be internal or external to the system.

Explain your reasoning clearly.

LIST OF ACTIVITIES

(c) Draw a Sequence Diagram for the Answer Calls Use Case to illustrate the above

scenario, using the appropriate syntax. You should indicate values clearly that are passed

in messages, or provide a paragraph explaining your assumptions.

Exercise #3: Software Planning using UML

Consider the following scenario:

Animals R Us is a zoo, in which there is a Monkey House, that contains monkeys all in one

big cage, and a Cat House that contains an open-air lion enclosure and an open-air tiger

enclosure. There is also a Bird House (Aviary), which contains birds in separate cages and onelarge enclosed cage that has birds flying free inside it. Animals R Us has a staff consisting of

Administrators (who deal with business matters, such as allocating staff identification numbersto the Keepers) and the Keepers themselves (who look after the animals). Each big House

(including the Aviary) has a separate Keeper, who feeds the animals every morning and cleansout their cages and enclosures every afternoon.

(a) Construct a UML Class Diagram using all the information provided in the above scenario.You should show aggregation, generalisation, and other associations, together with

multiplicity, attributes and methods, where appropriate.

(b) After a change of administrative staff at Animals R Us, it is decided that Keepers should beallocated a particular animal house for feeding and cleaning each day. So, the first thing that

a Keeper must do when he/she gets into work in the morning is to obtain details of their

Animal House for the day. At the end of the day, they have to hand in their worksheetdetailing what actions they had carried out, and when they had been done. Only after doing

this could they go home. Using the above extra information, in addition to that provided in

the original scenario, draw a UML Behavioural State Machine (State Chart) Diagram for an

object of theKeeperclass, using the appropriate syntax.

Exercise #4: Requirements Analysis

1) Refer to the Case Study of the New Century (Given by the Instructor).

2) Read and analyse the case study.

3) Highlight the questions used during the interview.

4) Create a set of interview questions for your own project.

5) Submit the questions for approval to your instructor.

LIST OF ACTIVITIES

3. Draw the ERD corresponding to the ff. Specify the attributes, Primary Key(s), cardinality

Persons (identified by Person-ID) work on machines (identified by MACHINE-NO) toproduce garments

Various garments can be produced. Each garment has an GARMENT-ID (its identifier) and a

description and is made up of a variety of materials. Material is identified by MAT-ID andalso has a description. A record of the quantity needed of each material for each garment is

stored The production of each garment is recorded as a job identified by JOB-NO. Each JOB-NO

has a START-TIME and an END-TIME and is performed by one person on one machine. A

number of garments of the same kind can be produced on one job Other information of interest is

a. The NAME and DATE-OF-BIRTH of each person

b.

The DATE-PURCHASED of each machinec. The DESCRIPTION of each MAT-KINDd. The TIME SPENT by a person on a job

e. The NUMBER-OF-GARMENTS produced on one job
