How to Create an Entity-Relationship Diagram

ERD (entity relationship diagram) is used to show the logical structure of databases. It represents the interrelationships between components of a database (entities). Entity relationship diagrams are widely used in software engineering. Using ERD software engineers can control every aspect of database development. ER diagram can be used as a guide for testing and communicating before the release of the software product. ERD displays data as entities that are connected with connections that show the relationships between entities. There are some ERD notations used by databases developers for representing the relationships between the data objects. ConceptDraw DIAGRAM and its ERD solution allow you to build ERD diagram of any notation.

Venn Diagrams are actively used to illustrate simple set relationships in set theory and probability theory, logic and statistics, mathematics and computer science, linguistics, sociology, and marketing. Venn Diagrams are also often used to visually summarize the status and future viability of a project.

How to Create a Data Flow Diagram

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw DIAGRAM allows you to draw a simple and clear Data Flow Diagram using special libraries.

How To Make Chen ER Diagram

The Chen ERD notation model is a popular standard and is widely used worldwide in database and software design. The entity-relationship model proposed by Dr. Chen is constructed using a natural view of how the real world comprises entities and the relationships that exist with these identified entities. It was designed to leverage the advantages of the three entity-data models (network model, relationship model, entity model). The free Chen Notation solution for ConceptDraw DIAGRAM provides vector stencil libraries with full standardized Chen notation included.
