What is a .ERD file?
An .ERD file is a special kind of diagram that shows how different parts of a database are connected. It's like a map that helps people who work with databases, like developers and analysts, understand how data is organized. This file is made using a tool called DBeaver, which is a program that many people who work with databases use to manage and look at their data.
In an ERD file, you'll see pictures of the database tables, which are like containers for data, arranged on a grid. There are also arrows that show how these tables are related to each other. This can be really helpful for understanding how information in a database is linked. You can either let DBeaver create this diagram for you automatically, or you can make one yourself to fit your needs.
To open an .ERD file, you use DBeaver. It's the main program that can read and show you what's inside these files.
The .ERD file is made up of two main parts. The first part is called the header, and it has information that tells other programs how to understand the data in the file. The second part is the actual data, which can be in the form of text or a more complex format called binary. If the data is in text, everything is kept in one .ERD file. But if it's in binary, the header is in the .ERD file and the data goes into a separate .BIN file. These two files need to have the same name and be in the same folder for them to work together.
This .ERD format was originally created by a group called the Engineering Research Division at the University of Michigan for a specific program that analyzes roads. But over time, it became a standard way to store and look at data about road profiles.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files. If you want to suggest edits or updates about .ERD file formats, example files, or programs that are compatible. Please contact us.
