UMLを知りたい！！

　I was assigned to draw " the Class diagram" of the part of our system.
This assignment gave me chances to study about UML.

To tell the truth, I didn`t know that UML is a kind of Rule for coding or making graphs.
I thought that is one of the language that I hadn`t studied yet,
because UML seems standing for unMarked Language or something....

I need to know about Object idea in the computer language more.

By the way, I realize my current job is a ideal one as I wanted to be in the future when I was a school student.
You know why? The class to study Visual Basic made me interested in computer language, especially, to make Graphical User Interface and do programming as the event.
