Is there a standard file format for representations of physical data models?

Is there a standard file format for representations of physical data models? And with that, I mean files, from where I can see graphically the relationships between data tables.

For example, in my work, we use the “Toad Data Modeler” to create physical data models from existing databases. These files have XML with the extension 'txp'. Since I cannot use the Toad anywhere (license cost $), I am looking at how to export the model to other formats, but the only option it has is an image, and this is problematic because I cannot search for text and image, and for large databases it is impossible to find something quickly.

If this file format does not exist, is there at least some defacto standard that can be interpreted from software with multiple values?

There is no such standard, unfortunately, for the Entity Relationship Model .

There is some work to create a standard for UML with XMI .

By the way, if your problem is that Toad Data Modeler is property, you can use the free version . Perhaps this will be enough to fit your needs.
