The software development life cycle is a sequence of steps and processes used to develop software, ranging from initial planning to ongoing maintenance. Typical lifecycle phases include requirements analysis, design, development, testing, deployment, and maintenance.

The waterfall model is a linear and sequential software development model. it consists of distinct phases that are executed sequentially, where each phase depends on the previous phase. Typical phases of the waterfall model are requirements analysis, design, development, testing and maintenance.

The agile approach is an iterative and collaborative software development method. it emphasizes rapid feature delivery, close collaboration with customers and cross-functional teams, adaptability to change, and continuous improvement. Popular agile methodologies include scrum, kanban and extreme programming (xp).

Test-driven development (TDD) is a software development approach where tests are written before production code. The tdd cycle generally follows the steps "write a test", "fail the test", "write the minimum code to pass the test", and "refactor the code". This approach promotes better test coverage and modular design.

A unified modeling language (UML) class diagram is a static visual representation of classes, relationships between classes, and class attributes and methods in a software system. It is widely used to model the structure of an object-oriented system and show the relationships of inheritance, association, aggregation, composition, etc., between classes.
