Er Diagram Tool Reverse Engineering

What is an ER diagram?

What do we mean when we talk about ER diagrams? Developers use ER diagrams to outline the design of a database. In times past, a database engineer could diagram database relations on a whiteboard. Nowadays, we need powerful tools to properly map out a database. ER diagrams graphically represent the relationships between different parts of a database. This allows team members to easily explain the database structure to all stakeholders.

So, what is an ER diagram? ER diagrams are flow charts that illustrate relationships between entities. Entities in this case refers to objects, concepts, events or people. ER diagrams give a clear view of how entities work with and relate to  each other.

Gleek is perfect for creating an entity-relationship diagram in Chen or Crow's foot notation.

How can ERDs help us?

ERDs can help teams to map complex relational databases. Teams use ERDs in the early planning states of new systems. Sometimes ERDs prove very useful for diagramming out existing systems. Whether used for planning or documenting current databases, ERDs allow teams to visualize how a database functions.

Let's take a look at the 11 best ER diagram tools out there. We will examine their best features and how they function.
