Yes,

Progress is a programming language itself and also has its own database.  Can develop applications, ERPs, etc  I guess it could be compared to Oracle with some limitations.

I have worked with Progress for almost a decade now.

It can be used in various industries...It also uses queries to interact with the database.

There are web applications as well.

Progress is more popular in Europe..
