UML Component Diagram is a type of Structure Diagrams that shows how components are connected to larger components or software systems, and shows the dependencies among these components.

Component-based development supposes that constructed components can be reused and replaced by some other components.

Components in UML can represent logical components and physical components. The behavior of components is defined in the terms of provided interfaces and required.

There are two types of connectors linking components: assembly connectors and delegation connectors.

Assembly connector is a connector between two components that allows to connect the required interface of one component with the provided interface of another component. Thus the assembly connector is described that one component provides the services that another component requires.

A delegation connector is a connector that describes how a component realizes the specification of behavior. When a delegation connector is assigned, the signals that arrive at the port will be delegated on the internal part. To communicate with external part it is necessary to delegate signals from the internal part to a port using the delegation connector.

Rapid UML Solution for ConceptDraw PRO contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.

To design a Component Diagram use the UML Component Diagram library.

UML Component Diagram library contains 36 shapes:

  • Component
  • Subsystem
  • List of required and provided interfaces
  • Realization arrow
  • Dependency arrow
  • Delegation connector
  • Aggregation (shared association)
  • Provided interface
  • Required interface
  • Ball and socket notation
  • State divider
  • Symbol
  • Port
  • Fragment
  • Note

UML Tool & UML Diagram Examples
You can use many tools to create a representation of a system behavior or a scheme of objects relationships. Some of them are quite abstract and useless, and some, like UML tools help clarifying both the structure and the behavior of a system. There are various types of uml diagrams and tons of examples explaining the difference between them. UML 2.2 specification has many kinds of diagrams. They are divided into two groups( structure and behavior diagrams). This class diagram shows the hierarchical structure of UML 2.2 specification. Class diagram - the most suitable tool for this task because it is designed to describe basic structure of a system. This diagram can be use as a visual aid for learning UML.  Read more... →

Entity Relationship Diagram Symbols
When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database projecting and for its' future maintenance. Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.  Read more... →

Components of ER Diagram
It is easy to recreate any informational system structure using diagrams. There are three main components of any ER diagram: entity, attribute and relationship. Basing on these three components, one can define other, less used elements, such as weak entity or relationship, derived attribute, recursive relationship etc. This is the set of graphic elements of ERD Chen's notation. This ERD notation is used to represent an entity–relationship models. It involves the set of geometric forms: rectangles - depicting entities, ovals - representing attributes and diamonds depicting relationships assigned for first-class objects, that can have relationships and attributes of their own. Connections are displayed with arrowed lines. It is known that the Chen's ERD notation is used to show a detailed view of entities and relationships. ConceptDraw Entity-Relationship Diagram solution from the Software Development section of Solution Park provides the ability to create ERD of database structure for software development purposes using the Chen’s notation elements.  Read more... →
