What is an Entity Relationship (ER) Diagram?
The entity relationship diagram is a high-level conceptual data modeling diagram. It helps with systematically analyzing and identifying data requirements needed for effective database designing.
This is generally the first step in thinking about a systems data design. You will first identify the entities and then create the detailed data model with actual table structures.
Creately supports all levels of Database Design with support for ER Diagrams, Database Diagrams , DFDs and UML models .
How to Make an ER Diagram Collaboratively with Creately?
Open a Creately workspace for your ER diagram. Creately offers an intuitive interface for drawing ER diagrams online with use-case based ER diagram templates. You can use Creately’s collaboration features such as real-time mouse cursors and synced previews to easily track the changes other participants make in the workspace.
Once you open the Creately workspace, enable the ER diagram library. You can share the workspace with other key team members to collaborate with them as you identify all the entities in the system. An entity should appear only once in a particular diagram. Create rectangles for all entities and name them properly.
Then identify relationships between entities. Connect them using a line and add a diamond in the middle describing the relationship. With Plus Create, Creately intelligently suggests the set of next shapes you need to add, cutting back the time taken to manually drag and drop them to the canvas.
Add attributes for entities. Give meaningful attribute names so they can be understood easily.
Organize the ER diagram in a logical way to increase comprehension. Once completed, you can export it in PDF, PNG, or SVG formats to embed in other sites or share it with others.
Use version control and history to track changes and revert to previous versions if necessary. This can help your team keep track of the progress of the diagram and ensure that everyone is working towards the same goals.

What is an entity relationship diagram tool?
An ER diagram presents a graphical representation of entities and the connections between them. Accordingly, a software program that enables users to build and edit ER diagrams is known as an ER diagram tool. For building and modifying the various elements of an ER diagram, like as entities, characteristics, and relationships, these tools often offer a user-friendly interface. The ability to create database schema from ER diagrams and vice versa is offered by many ER diagramming tools.
Some ER diagram tools might also offer functionality like data input and export, database reverse engineering, and real-time collaboration with other users.
