From Umass Lowell to Unified Modeling Language: A History of My Experience With the Term “UML”

Believe it or not, I have been coding since the year 2015. As the title implies, the first university that I attended (right out of high school) was the University of Massachusetts – Lowell. Interestingly enough, within my very first textbook at UML, I would be exposed to another kind of “UML” – Unified Modeling Language. At this time, Unified Modeling Language was little more than a reference at the back of the book; there was more written on the subject, but my mind was concentrating on concepts such as how to “calloc()” in C.

Fast forward 5 years, and now Unified Modeling Language takes on a larger role; it is being used for visual representations of classes and inheritance in Java code. This can be seen with the following YouTube video, “How To Make Easy UML Sequence Diagrams and Flow Charts with PlantUML” by user “Be A Better Dev”. Essentially, the video shows how Java code can be written and then turned into a UML chart for a visual representation of classes and their features.

Personally, I selected this particular video due to the fact that I enjoy using YouTube more than any other social media; this way, I can use the app for educational purposes as well as recreational ones. This nine minute video is a great way to learn about how to code for UML in a format that is digestible on a busy schedule (when at work, for example). In addition, I expect the material to be applicable to aspects of the course (such as homework and exams) due to it being another form of practice. Practice, practice and yet more practice is the most important way to retain any type of coding/programming knowledge, and UML is no different.

It’s crazy to think that something barely glossed over from my educational journey five years ago would be so prevalent in the present day. However, it makes sense; programming practices such as using an arrow (->) operator or parentheses for a method are given new meanings when working with UML. Extending this further, programming syntax can create additional effects within the PlantUML environment. For example, placing an arrow on one side or another of an entity will effect exactly where it extends from on said entity.

As a final note, I am glad that I am able to work with this newfound technology. Ever since my days at UML, I have been wondering about when my code would leave the IDE environment and tackle more “lively” features (such as a graphical interface). Thanks to Unified Modeling Language, I now have a method of making my code come to life.
