There are several things that must be considered in making ERD for database design. Each database must have entities that are interconnected and each entity must have attributes consisting of a primary key as the entity's characteristics and descriptive attributes. Many users fail to create databases due to errors in ERD creation. Conceptual errors, procedural errors, or technical errors. This article was created using the SLR method, namely reviewing various kinds of references that discuss database design, then drawing conclusions to make it easier for users to overcome problems that occur when making ERD and implementing them.
