Introduction to Unified Modeling Language (UML)
The UML can be used to Visualize, Specify, Construct and Document software applications.
Visualizing:
Specify:
Construct:
Document:
UML helps to document the decisions taken through various activities of software development including requirements, architecture, project planning, design, prototyping, coding, etc.
Conceptual Model of 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)
