What is a UML Diagram?
UML means with open expression Unified Modeling Language. As software technology develops, the complexity and difficulty of programs which are written is increasing. In Today’s world the software and hardware are intertwined. Large network systems are growing and it will be difficult to organize the complex systems and works. So, there is a need for a standard modelling and analysis language. UML is more suitable object oriented programming languages. If the problems can be divided into small parts and if there is a relation between these parts, the UML diagram can be used easily. For example; we can think of a restaurant. There is a relationship (may be direct or indirect) among a customer, a waiter and a cook. Such relationships are represented by various diagrams in the UML.
