Part 1. ER Diagram for Online Shopping
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.

You can insert ovals and rectangles to represent your entities and attributes. For weak-related entities, you can insert the shape twice and adjust the dimensions to the extent where you will get a weak entity illustration.
Step 3. After inserting your shapes, you can simply click on each shape and fill in the color or modify the border weight. Moreover, you can add text to each shape by clicking on the text icon or by pressing the T key to label your entities and attributes.
Step 4. Now it is time to connect your data. Just below the shape icon, there is a connection line tool, or simply press the L key. Over here, you can find lines with arrows and without arrows to perfectly connect your entities and attributes in your online shopping DMBS.
Using templates
A quick way to skip most of the creating is to head over to the template section by clicking on the template icon on the left-hand side panel. Once the template pop-up box appears in front of you, head over to the Draw & Diagram section and add a Flowchart to your canvas.
You can preview it first and then add it to your file. Once the flowchart is added to your Boardmix canvas, you can quickly modify each shape and connection to meet your online shopping DMBS needs.
