Curious about why we model data with an entity-relationship diagram (ERD)? You've come to the right place. An entity-relationship diagram, or ER diagram, is essential for modeling the data stored in a database. It is the basic design upon which a database is built. ER diagrams specify what data we will store: the entities and their attributes. They also show how entities relate to other entities. Another advantage of ERDs is that they represent the data in a graphical manner.
Depending on the purpose, we may need to create either a conceptual, logical, or physical data model. Find out the differences and use cases for each one. Data modeling implies identifying and defining entities and their relationships for a business solution. It requires a good understanding of the desired business outcome and is the foundation for creating a robust software solution. The different model types (conceptual, logical, and physical) have different levels of detail and are used at different stages of the software development process.
Are you a student or a beginning data modeler who wants to learn more about data modeling? Let’s start learning with the conceptual data model – the least detailed of the three models. In this article, we’ll discuss the conceptual data model using some real-world examples. As you know, data modeling is the process of describing real-world data – its relationships, features, and attributes – in a structured document like an ER (entity-relationship) diagram.
Are you searching for the best online ER diagram tool? Read on and discover our top picks. Data modeling is one of the most critical parts of a software project.
