What is a .DM2 file?
The .DM2 file extension is associated with a program called Toad Data Modeler 2. This type of file is essentially a data model, which means it's a way to design and organize databases. People use it to create visual diagrams that show how data in a database is related, which is very helpful for understanding and planning the structure of databases. These diagrams are known as entity relationship diagrams, and they can be made from scratch or generated from existing database files. This makes it easier to see how the database is put together.
To open a .DM2 file, you would use a program called Charonware Toad Data Modeler. It's important to note that Charonware has become a part of a larger company called Quest Software. So, when looking for this program, you might find it under the Quest Software name.
Additionally, it's worth mentioning that DM2 is also used to refer to a different concept in the world of databases. It stands for a Database Management System (DBMS) that was developed by a company called IBM. This is a separate use of the term and not directly related to the .DM2 file extension used by Toad Data Modeler 2.
