An ER diagram or Entity Relationship diagram is a visual representation of the entities and relationships found within an ecommerce website. It helps to identify the relationships between different types of data, such as customers and products, so that developers can create a logical structure for how information should be stored on the website. The diagram typically consists of rectangles for entities (like customers and orders) with lines connecting them to indicate how they are related. Additionally, it includes symbols to represent cardinality and other details. With an ER diagram, developers can quickly recognize any missing information from the database, helping them create a more organized data structure. With the help of EdrawMax, you can easily recreate a similar diagram.
