This Online Shopping System ER-Diagram Example includes all necessary information, such as field names, descriptions, data types, and character lengths. These tables represent data storage characteristics and attributes. The field column lists each database's features, while the description, type, and length columns describe each detail's purpose and data type. Overall, the tables are a starting point for developers to design the database for the online shopping system. It contains a detailed description of the database. The developers will then incorporate this into the program. You can also use it as is or modify it to meet the requirements of your project.
