OOAD with UML
Object-Oriented analysis and design with Unified Modeling Language is the first step and therefore quite important in software life cycles. Object-Oriented Analysis Design with Unified Modeling Language (OOAD/UML) presents the concepts and techniques necessary to effectively use system requirements captured in use cases to drive the development of a robust design model.
The Unified Modeling Language (UML) is object-oriented development approach, and represents the unification of the Rumbaugh's OMT, the Booch method and Jacobson's Objectory. We build a Model of complex system because we cannot comprehend such a system in its entirety.UML is one language for all practitioners.
Modeling helps us to achieve four aims.
- Helps us to visualize a system as we want it to be.
- Permits us to specify the structure or behavior of a system.
- Gives us a template that guides us in constructing a system.
- Documents the decisions we have made.
Requirement Management
Requirement is always important for every project and it is crucial in identifying and managing the business needs of customers and stakeholders in order to determine appropriate solution to the business problems. Requirement Management is systematic approach to eliciting, organizing, documenting and managing the changing requirements of software application.
Major Aspects of Requirement Management
-
Analyzing the Problem
- Understanding User needs
- Defining the system
- Managing Scope
- Refining the System Definition
- Building Right System.
