What are the benefits or disadvantages of ER diagrams? Why bother with logical design and not just create tables and columns (physical design) directly? The Advantages and Disadvantages of ER Diagrams An entity-relationship diagram (ERD) is a diagram that depicts or shows the relationship between entity sets in databases. Databases are critical systems that improve the storage of data collected from various sources. Most data in healthcare institutions is collected and stored for future reference and analysis in order to determine approaches that can be used to improve operational processes (Saad & Muniandi, 2020). ER diagrams frequently depict the relationship between the entity sets of data stored in databases. In a nutshell, ER diagrams help to explain the logical structures of databases. The three most common concepts used to create ER diagrams are relationships, attributes, and entities. There are various symbols that are always used when creating ER diagrams. Rectangles are used to represent entities, diamond shapes to represent relationships, and ovals to define attributes.

The Advantages of ER Diagrams Database managers or database managers can use ER diagrams as a plan or outline for the implementation of data or information in specific software applications. ER diagrams in database design and management allow designers to interact with the logical structure of the database to users (Supriadi & Oswari, 2020). ER diagrams also help to define terms related to entity-relationship modeling. Furthermore, ER diagrams provide a preview of how tables should be connected as well as consideration of fields that should be included in these tables. The Drawbacks of ER Diagrams ER diagrams lack standardization; in other words, there are various versions that can be confusing. Furthermore, the ER diagrams may be insufficiently concise and expressive. ER diagrams can be ambiguous in some cases. Finally, ER diagrams are typically used or applied only to relational databases. In order to improve the visual presentation of the database under consideration for specific requirements, logical design is required. Logical designs improve or aid in the staging of the connection between database objects and business requirements. Order Now
