The Class model - Systems Analysis and Digital Product

Course details

Building the class model is the first and most crucial step in information system analysis.

Countless projects failed and billions of dollars went to the history garbage, because the first step,- to deeply understand the business domain- has been done negligently.

It doesn't have to be like this anymore!

Building the Class model guides you by a very structured and solid method on how to understand and analyze the domain.

It really forces you to think in a structured way; It doesn't let you delude yourself that you "understand" the business world because it forces you to build a model: With strict logic and rules and in well-defined language (UML) with a wealth of options.

In theory, theory and practice are the same, but in practice - they are not!

The course takes a very pragmatic approach.

No more long and boring theoretical academic introductions, no more naive examples with no relevance to real life, and no more long educated argumentation about delicate nuances that don't really matter in real life.

Right from the start, Iwill introduce a real-world test case. This test case will accompany us throughout the course. In every lecture Iwill add more details that will reflect the complexity of real test case and will set the stage for adding more concepts and "wisdom" to the class model.

We will conclude the course with a very accurate (and elegant) class model that will reflect completely our complex business domain.

Since building a class model is quite a challenging mission, I will teach you how to work with CASEtools (Computer Aided System Engineering).

From the beginning, all your work will be done with leading CASEsoftware, which is been used by real system analysts in real projects.

We will learn and practice:

• Classes and objects

• UML(the Unified Modeling Language) - what it is, why it's so crucial to the analysis process

• The association relationship

• CASE tools - Why, what and how to use it

• How to enhance our test case

• Constraints

• Recursion

• The association class

• The inheritance relationship

• Refining attributes

• The data def stereotype

• The Enum stereotype

• The composition relationship

• Managing historical data

Since Ibelieve in hard work, you need to practice, practice and then practice again.

In the supplementary section of the course, you will find more test cases from various business domain. You are highly recommended to use it!

My name is Yosi Wiesel. I have a passion for information systems. I have a passion for the magical journey, when we take some abstract, vague idea, and realizing it to a real working software system.

And I have a passion to share with you my knowledge and insights.

Let's start!

Have fun and productive studies!
