UML (Unified Modeling Language) is a modelling language used to document and design software systems. The document discusses various UML diagram types including activity diagrams, use case diagrams, class diagrams, state diagrams, and sequence diagrams. It provides examples of each diagram type applied to a medical practice management system (MHC-PMS) and explains how UML diagrams are used in software development and business process documentation.

- 4. WHAT IS UML? • UML stands for “Unified Modelling Language”. It is a modern approach to modelling and documenting software. • UML is being used as a “General-Purpose Modelling language” in the field of software engineering. • It is based on “diagrammatic representations of software components”. • UML is a very important part of developing object oriented software and the software development process. • UML uses mostly graphical notations to express the design of software projects. 4UML DIAGRAMS

- 6. ACTIVITY DIAGRAMS • UML Activity diagrams helps to describe the activities involved in a process or in data processing. It is object-oriented equivalent of flow charts and data-flow diagrams (DFDs). 6UML DIAGRAMS
- 8. USE CASES DIAGRAM UML Use cases diagrams describes the interaction between a system and its environment. A UML Diagrams contain the following components: • Use cases . A use case describes a sequence of actions that provide something of measurable value to an actor and is drawn as a horizontal ellipse. • Actors . An actor is a person, organization, or external system that plays a role in one or more interactions with your system. Actors are drawn as stick figures. • Associations. Associations between actors and use cases are indicated by solid lines. An association exists whenever an actor is involved with an interaction described by a use case. 8UML DIAGRAMS

- 13. CLASS DIAGRAM • UML class diagrams are used when developing an object-oriented system to show the object classes in the system and association between these classes. 13UML DIAGRAMS

- 16. STATE DIAGRAM • UML State diagrams can show how the system reacts to internal and external events. 16UML DIAGRAMS
- 19. SEQUENCE DIAGRAM • UML Sequence diagrams described the interaction between actors and the system and also between system components on a time sequence. It shows how the objects interact with others in a particular scenario of a use case. 19UML DIAGRAMS

- 21. USE OF UML DIAGRAMS: Mainly, UML has been used as a general-purpose modelling language in the field of software engineering. However, it has now found its way into the documentation of several business processes or workflows. For example, activity diagrams, a type of UML diagram, can be used as a replacement for flowcharts. They provide both a more standardized way of modelling workflows as well as a wider range of features to improve readability and efficacy. UML itself finds different uses in software development and business process documentation: 21UML DIAGRAMS
