Example 1. What is Entity-Relationship Diagram, Crow's foot notation
Creating an entity relationship diagram requires using a specific notation. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Five main components of common ERD notations are Entities, Actions, Attributes, Cardinality and Connections.
Example 2. What is Entity-Relationship Diagram, Chen's notation
ERD notations
The two of notations most widely used for creating Entity-Relationship Diagrams are:
- Chen's notation
- Crow's foot notation.
Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling. By the way, the Crow's foot notation originates from the Chen's notation - it is an adapted version of the Chen's notation.
Professional ERD drawing implies knowing of ERD symbols and meanings. Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data.
This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.
