UML Component Diagram. Design Elements
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 DIAGRAM 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

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.

When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.

Structured-systems analysis and design method uses data flow diagrams to represent the process of data flowing through a system. Talking about this might be useless without a proper example of DFD for online store (Data Flow Diagram). This DFD example shows all the distinctness that a diagram can bring into a scattered data structure.
Data flow diagrams are used to show how data is processed within some business processes. Making DFD is a common practice for business process modeling and analysis. This diagram represents the online store business flow. It describes inputs and outputs within online selling process and depicts the interactions between its participants. This DF diagram can be used by system analysts to create an overview of a business, to study and discover its inherent strengths and weak points.
