Entity Relationship Diagram Examples

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 DIAGRAM 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.

Entity Relationship Diagram Symbols

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 DIAGRAM software.

Data Modeling with Entity Relationship Diagram

Data modeling is actively applied in analysis and uses wide set of methods for description the data requirements in a system. One of the most popular and well-known is the ERD method of database modeling. The best ERD tool for the Mac and Windows is ConceptDraw DIAGRAM software extended with the Entity-Relationship Diagram (ERD) solution from the Software Development Area for ConceptDraw Solution Park, which is sharpened for professional ERD drawing and data modeling with Entity Relationship Diagram.

Risk Diagram (Process Decision Program Chart)

The Risk Diagram or Process Decision Program Chart (PDPC) is intended to determine the risks of potential obstacles during the corrective actions that can be at the cases of their incorrect performing, and helps to develop effective preventive actions. Process Decision Program Chart it's kind of contingency plan to limit the risks, it determines the consequential impacts of failures on the activity plans. The Risk Plans and Process Decision Program Charts can be extended on several levels and take the form of tree or hierarchy, this form is incredibly convenient for representing the risks and countermeasures. ConceptDraw MINDMAP is powerful software tool for Business, Marketing and Project Management. It is also ideal for easy designing MINDMAP Risk Diagram or Process Decision Program Chart, due to the included "7 Management and Planning Tools" solution to ConceptDraw Solution Park. We recommend to start with Process Decision Program Chart (PDPC) template opening it from ConceptDraw STORE or from the Output tab at ConceptDraw MINDMAP application.

Data structure diagram with ConceptDraw DIAGRAM

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw DIAGRAM.

Concept Maps

As concept map consists from conception-blocks and links between them, you can use ConceptDraw library objects and add to a document as much objects as you need. ConceptDraw tools let you to edit, group, move objects, change their appearance and add text signs and raster or vector pictures. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Concept Maps Solution from the "Diagrams" Area is effective tool for creating professional looking Concept Maps.
