How to Create an ERD Diagram

Entity-Relationship Diagram (ERD) using Chen's notation
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.
The vector stencils library "EPC diagrams" contains 23 EPC symbols.
Use it for drawing event-driven process chain (EPC) diagrams in the ConceptDraw PRO diagramming and vector drawing software extended with the Event-driven Process Chain Diagrams solution from the Business Processes area of ConceptDraw Solution Park.

"Flow Charts ...
Pictures, symbols or text coupled with lines, arrows on lines show direction of flow. Enables modelling of processes; problems/ opportunities and decision points etc. Develops a common understanding of a process by those involved. No particular standardisation of symbology, so communication to a different audience may require considerable time and explanation." [ifm.eng.cam.ac.uk/ research/ dstools/ tqm-tools/ ]
