Definition that is uml diagram
In UML, the class definition is represented by a rectangle. The name of the highest grade class of the rectangle, the gold features and the golden pictures on it. In the class display above, our car is the name of our class. WheelStyle and Model. The special type is specified as: byte and: string. The WheelSize property defaults to 4. The + and – signs at the beginning of properties and functions also indicate the level of access. Marks the public at the level of public (accessible to other classes).
Show the pointer at the protected level (accessible from within the class and from descendant descendant classes).
The – sign specifies that you are on a special (only accessible from within the class) level. Three functions are defined in the car class. 1. The ArizaKontrol function returns bool values and does not receive any parameters. 2. The ArizaCheck function takes the parameter and returns the bool values backwards. The init function does not take parameters and does not return any value.
Inter-Class Relationship (Assocation)
Relationships for classes are indicated by a line and the relationship is written on the line. Interclass relations can be individual, individual, individual. In the e-commerce system of the company, the relationship between Customer and Product is shown.
According to the above uml diagram, the customer and product areas are to be purchased and they have to create Order. The diagram above also has an individual relation. This diagram shows that there may be n products in a sepette. As such, individuals may have relationships. The class may also have a relationship with itself. A Customer Representative and Customer. Both of these are done by the person. The representative belongs to more than one customer. We can state this as follows.
Derivation (inheritance), Interface (Interface) and Inclusion (Aggregations)
For example, there are project clients and manager classifications, and we derive these classes from the User class. We can do this as follows. If a class is made up of other pieces, the relationship between them. For example, if we consider the car class as consisting of 1 Engine, 1 Body and 4 Tires, the relationship between them is shown as follows. When the original class is produced, it is called composite when it is produced. If the engine, chassis and tire classes are to be created, the internal empty rectangle is shown as full. The interfaces are also shown in a similar fashion. But interfaces do not have a property definition, and it is specified to interface with <interface>. The relationship between the class and the interface has a broken line and the interface is in the form of an empty triangle in the Uml diagram.
Finally, the history of the uml diagram. The birth of UML has been one of the biggest developments in the software industry in recent years. UML was created in 1997 by a standards committee to express the software in diagrammatic form.
