What are the UP Disciplines? - UML

The UP describes work activities, such as writing a use case, within disciplines a set of activities (and related artifacts) in one subject area, such as the activities within requirements analysis. In the UP, an artifactis the general term for any work product: code, Web graphics, database schema, text documents, diagrams, models, and so on.

There are several disciplines in the UP; this book focuses on some artifacts in the following three:

  • Business Modeling The Domain Model artifact, to visualize noteworthy concepts in the application domain.
  • Requirements The Use - Case Model and Supplementary Specification artifacts to capture functional and non - functional requirements.
  • Design The Design Model artifact, to design the software objects.

A longer list of UP disciplines is shown in Figure.

In the UP, Implementation means programming and building the system, not deploying it. The Environmentdiscipline refers to establishing the tools and customizing the process for the project that is, setting up the tool and process environment.

What is the Relationship Between the Disciplines and Phases?

As illustrated in Figure, during one iteration work goes on in most or all disciplines. However, the relative effort across these disciplines changes over time. Early iterations naturally tend to apply greater relative emphasis to requirements and design, and later ones less so, as the requirements and core design stabilize through a process of feedback and adaptation.

Relating this to the UP phases (inception, elaboration, ...), Figure illustrates the changing relative effort with respect to the phases; please note these are suggestive, not literal. In elaboration, for example, the iterations tend to have a relatively high level of requirements and design work, although definitely some implementation as well. During construction, the emphasis is heavier on implementation and lighter on requirements analysis.

How is the Book Structure Influenced by UP Phases and Disciplines?

With respect to the phases and disciplines, what is the focus of the case studies?

The earlier chapters introduce activities in inception; later chapters explore several iterations in elaboration. The following list and Figure describe the organization with respect to the UP phases.

  • The inception phase chapters introduce the basics of requirements analysis.
  • Iteration 1 introduces fundamental OOA / D and assignment of responsibilities to objects.
  • Iteration 2 focuses on object design, especially on introducing some high - use "design patterns."
  • Iteration 3 introduces a variety of subjects, such as architectural analysis and framework design.
