Exercise 1. Conceptual Modeling

• Each team makes a visual model representing the
  relationship between the concepts shown on the
  slide Concepts Focused.
• Both the concepts and their relationships are
  essential. Try to be both visual, informative and
  precise.
• Use the blackboard. It is as the ideal platform
  for your modeling teamwork.
• After 20 minutes the model will be presented on
  the blackboard by each team and discussed in
  plenum.

3
Exercise 2. Problems and Solutions in SDLC

• 2.1. Discuss the problems related to the use of
  the System Development Life Cycle (SDLC). If
  possible, relate to well-known disasters of
  system developments, or your own experiences.
• 2.2. Find reasons to the problems, and suggest
  some solutions to the problems

4
Exercise 3.Classes and Associations

• This exercise focus on classes and associations.
  The blackboard will be used, and the exercise
  will be carried out in plenum.
• A typical company is used as the system
  boundary, and the class Person is chosen
  initially.
• Student 1. Choose another Class
• Student 2. Suggest an association between Person
  and
• on of the Classes already presented
  on the
• blackboard.
• Student 3. Go to Student 1. Start from the
  beginning
• At the end, make a discussion of the model in
  plenum.
• (Please archive the result for later use)

5
Exercise 4.Classes and Attributes

• Make a class model based on a project, on a
  project company or eventually based on a part of
  the class model from Exercise 3.
• Discuss and define at least 2 attributes for
  each of at least 7 related classes in the class
  model.

6
Exercise 5.Classes and Multiplicities

• Make a class model based on a project, a project
  company or eventually based on a part of the
  class model from Exercise 3.
• Discuss and define multiplicities for the class
  model.

7
Exercise 6.Class Modeling. Tandem Exercise.

• Make a small description (maximum 7 lines) of a
  real or of a synthetic system.
• Make your own rough sketch of the corresponding
  class model. Keep this class model secret to the
  other team.
• Exchange only your description with another
  team, and make a model based of their similar
  description.
• When finishing this modeling, try to compare the
  2 class models corresponding to the same
  description. Discuss the differences. Which
  differences at acceptable? Are there any
  mistakes?
• Involve the lecturer, whenever needed.

Exercise 7.Project Defined System Development

• 7.1. Define content and boundary for a part of
  your semester project, suitable for system
  development.
• 7.2. Based on the OOAD 1, and UML 2
  literature, you shall carry out a
• System Choice
• Problem-Domain Analysis
• Application-Domain Analyses
• 7.3. Based on 7.2. you shall design a relational
  database, populate it and test it.

9
Exercise 8.Problem-Domain Analysis

• 8.1. Based on at short description of your
  project - or a part of your project - you shall
  carry out a tandem analysis, similar to exercise
  6.
• Do include following if possible
• - Attributes
• - think out some good identification attributes
• - prepare for implementation in a relational
  database (RDBMS)
• - Named associations
• - Multiplicities
• - Generalization
• -take advantage of inheritance
• - Decomposition
• 8.2 Consider why and how to store metadata from
  the class model
• Only use UML2 standard symbols, and feel free to
  model using a tool like Visio or UMLET
