This document provides an overview of a mentoring session on Unified Modeling Language (UML) and software projects. It discusses object-oriented concepts, the purpose and history of UML, the main UML diagrams including use case diagrams, class diagrams, sequence diagrams, and their uses. Examples are provided of how to implement UML diagrams to model real-world systems and software applications.

UNIFIED MODELLING LANGUAGE (UML)
- 1. Prof. M.Shamsunder. S (B.Sc, MCA,MBA) JIMS, Tathawade, Pune M E N T O R I N G S E S S I O N Unified Modeling Language (UML) Software Projects
- 2. Agenda Object Oriented characteristics Introduction to UML Purpose of UML UML Diagrams UML Notations Practical Implementations of UML Diagrams through Examples.
- 3. Following are some fundamental concepts of object oriented world: Objects: Objects represent an entity and the basic building block. Class: Class is the blue print of an object. Abstraction: Abstraction represents the behavior of an real world entity. Encapsulation: Encapsulation is the mechanism of binding the data together and hiding them from outside world. Inheritance: Inheritance is the mechanism of making new classes from existing one. Polymorphism: It defines the mechanism to exists in different forms.
- 4. UML is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. UML was created by the Object Management Group (OMG) and UML 1.0 specification draft was proposed to the OMG in January 1997. OMG is continuously making efforts to create a truly industry standard. UML stands for Unified Modeling Language. UML is different from the other common programming languages such as C++, Java, COBOL, etc. UML is a pictorial language used to make software blueprints. UML can be described as a general purpose visual modeling language to visualize, specify, construct, and document software system. Although UML is generally used to model software systems, it is not limited within this boundary. It is also used to model non-software systems as well. For example, the process flow in a manufacturing unit, etc.
- 6. UML includes the following Nine diagrams 1. Use case diagram 2. Class diagram 3. Object diagram 4. Sequence diagram 5. Collaboration diagram 6. Activity diagram 7. State chart diagram 8. Deployment diagram 9. Component diagram

- 9. CLASS Diagram Describing the static view of the system. Showing the collaboration among the elements of the static view. Describing the functionalities performed by the system. Construction of software applications using object oriented languages.
- 11. Object Diagram Object diagrams can be imagined as the snapshot of a running system at a particular moment. Making the prototype of a system. Reverse engineering. Modeling complex data structures. Understanding the system from practical perspective.
- 12. Sequence Diagram • It is an interaction diagram. • The sequence diagram communicates with object of one class with object of another class. • The interaction is through method and messages. It has four major objects • Actor Object • Interface object • Controlling objcet • Entity Object
