An Entity-Relationship Diagram is also known as ERD. This will show the relationship of the different entity sets that are located in one database. The entity is usually an object or one of the components of data. It is essential that the various bodies will be defined as this will make sure that the relationships between them will be carefully shown.

The ERD will show the links in a more precise manner so that they will also be easier to understand. Some people may still not know how to read an ER diagram. It does not have to be too complicated. You need to understand what the entities are and then identify the relationships between the objects. They can be connected with the use of lines. A diamond can be placed in the middle to signify their bond.
