1.1 What is an ER diagram?

An ER diagram or an entity relationship diagram is an illustration that depicts relationships among various objects, people, etc., within a database management system (DBMS). ER Diagrams visually represent the data and show how each entity can be related to one another.

1.2 What is the purpose of creating an ER diagram for online shopping?

First and foremost, ER diagrams are important when it comes to specifying the data we store—which mainly includes the entities and its attributes. An entity is the individual data that is distinguishable from other entities, while its attributes are the key elements describing the characteristics of that entity. As a result, it promotes clear graphical representation—making it easier for people in the business to interpret data.

Hence, when it comes to online shopping, there are a lot of steps involved from the point of first contact with the customer—all the way through the customer journey—and ending with the delivery of the product. For that, to manage everything efficiently within an information system, an ER diagram is most useful to determine the relevant information required for each step in the online shopping process.

Drawing a well-explained ER diagram for online shopping purposes shouldn’t stop you and it is much easier now to create them online using templates or drawing it freely in a whiteboard solution. Let’s move on to the next section to learn more.
