The set of attributes declared as unique are unique to the entity. State Diagrams show the different states of an Object during its life and the stimuli that cause the Object to change its state. Yml Diagrams are a special form of State Diagrams, that only or mostly contains Activities. Compositions are associations that represent very dde aggregations. Class Diagrams show the different classes that make up a system and how they relate to each other.

They also show interfaces and objects class instances. A State belongs to exactly one class and represents a summary of the values the attributes of a class can take.

In UMLassociations are represented as lines connecting the classes participating in the relationship, and can also show the role and the multiplicity of each of the participants.

Interfaces are abstract classes which means instances cannot be directly created of them. It may be an object with a physical existence example, Computer, Robot or it may be an object with a conceptual existence eq: The constraint must be a predicate. When the derived entities are not constrained to be disjoint, their set of entities are said to be in overlapping specialization.

A check constraint is applied to each row in the table. Umbrello showing an Entity Relationship Diagram. Visual representation of an entity in an ER Diagram.

Sequence Diagrams show modeeller message exchange i. Deployment diagrams show the runtime component instances and their associations. Umbrlelo do not represent the physical people or systems, but their role. Activity Diagrams support sequential as well as parallel Activities. Object is created Object receives message listen A Client requests a connection over the network A Client terminates a request The request is executed and terminated Object receives message stop etc.

Actors can be in real life people for example users of the systemother computer systems or external events.

A derived Entity is said to be a Category when it represents a collection of objects that is a subset of Union of the distinct entity types. Modellre lines Text Notes and anchors Boxes.

Use Case Diagrams tell, what the system should do but do not — and cannot — specify how this is to be achieved. Manyal messages have a vertical box on the side of the called object to show the flow of program control.

They have no logical meaning in the model. Messages can umo either synchronous, the normal type of message call where control is passed to the called object until that method has finished running, or asynchronous where control is passed back directly to the calling object.

They depict the various entities concepts in the information system and the existing relationships and constraints between them. Operations can, just umbrelloo Attributes, display their visibility:. This means that manua entity can be a member of at most one of the derived entities of the specialization.

Each end of the association also has a multiplicity value, which dictates how many objects on this side of the association can relate to one object on the other side.

In UMLCompositions are represented by a solid rhomb on the side of the whole. A check constraint also known as table check constraint is a condition that defines valid data when adding or updating an entry in a table of a relational database. In Collaboration Diagrams messages sent from one object to another are represented by arrows, showing the message name, parameters, and the sequence of the message. A Class defines the attributes and the methods of a set of objects.

They exist only inside the whole, and if the whole is destroyed the parts die too. Use Cases are descriptions of the typical interactions between the users of a system and the system itself. In UMLGeneralizations are represented by a line connecting the two classes, with an arrow on the side of the base class.

The time axis is also vertical, increasing downwards, so that messages are sent from one Object to another in the form of arrows with the operation and parameters name.

It describes the connection between different classes the connection between the actual objects is called object connection, or link.

Activity Diagrams describe the sequence of activities in a system with the help of Activities. Unique Keys and Primary Mofeller uniquely identify a row in a table entity.

An Aggregation modfller how the class that takes the role of the whole, is composed has of other classes, which take the role of the parts.

Objects are instances of classes. Ready Listening Working Stopped.
