Overview of UML

Introduction to Unified Modeling Language (UML)
  • It is a standard language to analyze, design and document software applications to enhance understanding and facilitate communication 
  • Using UML we can represent different perspectives of a system, both for the customers and for the development team 
  • Examples: 
  • Hospital management system, University management system, Retail billing software, Internet banking system, etc.

The UML can be used to Visualize, Specify, Construct and Document software applications.

Visualizing:
  • There are things about a software system that you cannot be understood unless we build models.
  • A program written by a developer can be difficult to understand by others unless it is documented or modeled
  • UML helps to communicate such conceptual models effectively to all the members involved

Specify:
  • UML allows to build precise, unambiguous and complete models to specify things such as requirements and design of a system
  • Example: Through use case mode, we can specify the requirements of software applications. A class model can be used to specify design.

Construct:
  • UML models can be used to map with some programming languages like Java, C++, Visual Basic or even database tables
  • UML mapping permits forward engineering (model to code) and reverse engineering (code to model)
