The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style.
The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw PRO software. Read more

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database.
ConceptDraw PRO professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity. Read more

UML Activity Diagram is a type of UML diagrams, which illustrates the business and operational step-by-step workflows of components within a system and shows the overall flow of control. UML Activity Diagram is constructed from a limited number of shapes, connected each other with arrows. The most important shape types are rounded rectangles, diamonds, bars, black circle, encircled black circle. The arrows represent the order in which activities happen and run from the start towards the end. ConceptDraw PRO software enhanced with Rapid UML solution is ideal for software designers and software developers who need to draw the UML Activity Diagrams and other types of UML diagrams. It is convenient to use the appropriate stencils of UML notation from the UML Activity library included to the Rapid UML solution of ConceptDraw Solution Park and containing a lot of specific vector UML objects. Use them to design your own UML Activity Diagrams, make them colorful and attractive with style tools of ConceptDraw PRO software. Read more
UML Deployment Diagram depicts the physical deployment of artifacts on nodes (nodes are the existing hardware components, artifacts are the software components running on each node); and how the different pieces are connected.

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation.
ConceptDraw PRO as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution. Read more

An Entity Relationship (ER) Diagram is a type of flowchart that illustrates the logical structure of databases, how the different entities, such as people, objects or concepts relate to each other within a given system. How to draw ER Diagrams fast and easy? ConceptDraw PRO diagramming and vector drawing software enhanced with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park offers you the powerful abilities of designing the ER Diagrams and ERD drawings without efforts. This solution includes a lot of predesigned icons advocated by popular Chen's and Crow’s Foot notations, which can be used when describing an enterprise database and depicting it by abstract way. Simply drag the required objects to ConceptDraw document, connect them in a desired way and make style settings. But the easiest and fastest way of drawing ERDs is to make them on the base of ready-to-use Chen ERD and Crow's Foot ERD templates, which are both represented at ConceptDraw STORE. Read more
