Today, C++, C#, Java, Visual Basic.NET and Python are popular object-oriented languages. The following compares basic OOP terms with traditional programming. See object-oriented DBMS.

Many LabVIEW programmers already perform object-oriented programming (OOP). The basic building block is the VI, which is comparable to a subroutine with multiple input and output parameters.
