Example 1. Components of ER Diagram, Crow's Foot and Chen's notations
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
Most other notation systems are adaptations, or use part of these original styles. Here is a brief list of some of other standards that have been developed:
- Bachman notation
- Barker’s notation (ERDs for Oracle)
- EXPRESS and EXPRESS-G notation
- IDEFX1
- UML class diagrams
- Merise
- Object role modeling
- (Min – Max) notation
Example 2. ER Diagram, Chen's notation
ERDs are an invaluable tool for software engineers, particularly since computing capacity, and thus data storage capacity, has markedly increased in recent years. They allow every aspect of database design to be managed, tested and communicated before implementation. Because ERDs have such a broad scope of influence across database activities, it’s imperative the standardized notation can be utilized and interpreted by a wide variety of stakeholders.
Example 3. ER Diagram, Crow's Foot
The Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park extends ConceptDraw DIAGRAM ector graphics and diagramming software with the ability to draw your own entity relationship diagrams using Chen's or Crow's Foot notations applying 2 libraries with numerous predesigned ER icons:
- ERD, Chen's Notation library
- ERD, Crow's Foot Notation library
Example 4. ERD Solution
The samples you see on this page were created in ConceptDraw DIAGRAM using the components of ER diagram from the libraries of Entity-Relationship Diagram (ERD) Solution. An experienced user spent 10-15 minutes creating each of these samples.

Of course it is possible to keep network records in text documents, but it is very difficult to use them later. A more sound way to keep such documentation is to create a network diagram that might represent either logical network structure or physical. These diagrams are easy to understand and you will thank yourself later.
There is a physical network diagram. It is a tool to represent, maintain and analysis of network equipment and interconnections. Network diagram depicts the actual network information in the attractive clear graphic form. One can learn here the LAN cable length, telecommunication type and carrying capacity. The diagram depicts servers, IP address and domain name as well. Also it shows location of hubs, switches, modems, routers, and other network equipment. The sets of special symbols and images delivered with ConceptDraw Network Diagrams solution are used to show network components. Symbols have a standard view. Therefore, various specialists can read the network diagram without any discrepancies.
