An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch

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 PRO provides vector stencil libraries with full standardized Chen notation included.

How To Make a Crow's Foot ER Diagram

The Crow's Foot ERD notation is often used in software engineering and database design. The originator of Crow’s Foot notation was Gordon Everest, who offered the idea of how to visually represent the different types of relationships that can exist between objects in an entity relationship diagram (ERD). The Crow’s Foot notation is often used in ER models to how a particular table data can reference data in other tables within a database. The free Crow's Foot Notation solution for ConceptDraw PRO offers a complete vector stencil library containing full standardized symbols of Crow's Foot notation.

How to Create an ERD Diagram

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