Definition - What does DBMS Interface mean?
A database management system (DBMS) interface is a user interface which allows for the ability to input queries to a database without using the query language itself. A DBMS interface could be a web client, a local client that runs on a desktop computer, or even a mobile app.
Techopedia explains DBMS Interface
A database management system stores data and responds to queries using a query language, such as SQL. A DBMS interface provides a way to query data without having to use the query language, which can be complicated.
The typical way to do this is to create some kind of form that shows what kinds of queries users can make. Web-based forms are increasingly common with the popularity of MySQL, but the traditional way to do it has been local desktop apps. It is also possible to create mobile applications. These interfaces provide a friendlier way of accessing data rather than just using the command line.
