Software Engineering: Phenomena and Concepts

-



This'll be a sort of abridged summary of the topic, any more information you might need, I recommend you try the book (name in bottom of the post).


When talking about concepts and phenomena (in the context of the book) as follows:

  1. Phenomena - It is what we refer to as Reality, as in things we perceive in the real world, things that are concrete.
  2. Concepts - More abstract, it is the idea of a given phenomena.
An example of this can be something like a Car.

  • Phenomena: Automobile -> Concept: Car
A car is a concept (an idea) of an automobile, where an automobile can be anything in the real word that serves that specific purpose.

We can also take things a step further, with the type of entity that we use.
  • Atomic Entities
  • Compound Entities
Atomic Entities: Individual entities, broken down to it's most basic representation. (For the purpose of the domain that you wish to represent)
Example:
  • Chair
  • Desk
  • Monitor
  • Computer
  • Keyboard
  • Mouse
  • etc.
Compound Entities, as the names suggest is... well a compound. Formed from two or more atomic entities creating a new entity.

Taking the previous example:
  • Work Station = Chair x Desk x Monitor x Computer x Keyboard x Mouse
Now Work Station is our Compound Entity!

JavaFX Snake Game (WIP)

-
Image
It's been a while, busy with classes. Decided to work on another little side project. Using what I've learned so far in my Java course, I wanted to test my JavaFX knowledge with this little game. Using GridPanes, Squares and Timeline Loops, I'm almost 85% done with the game, Snake eats and grows. Just need to add the lose conditions and that should do it. The game for now starts automatically. (So I need to add I title screen/pause screen) Link to the project on GitHub.

Where have I been?

-
It's been quite a while hasn't it? Where to begin, well shortly after my last update I was quickly hired by Hewlett-Packard Enterprise for almost two years now. How time sure flies doesn't it. I work there as a System's Software Engineer full time, working on diagnostic software for their many line of servers. It has been a great experience, all that I learnt and continue to learn is amazing. This is mostly the reason why this hasn't been updated since. But I started to miss these updates and hopefully soon I'll continue working on these. Sharing cool tips and tricks I've learned in the Industry or in my spare time. Got plenty of time, considering everything going on with this whole COVID-19 nonsense.Stay indoors fellas and wash your hands please!

Software Engineering: Documents

This'll be a sort of abridged summary of the topic, any more information you might need, I recommend you try the book (name in bottom of the post). In the professional realm documentation is everything (according to this book, it's probably true), lack thereof can make your job a living nightmare every time there's an update. Even if tedious proper documentation can go a long way. In Dines' Book there are 3 main types of documentation, each different but of equal importance. Informative Documentation Descriptive Documentation Analysis Documentation It can get a bit tricky trying to differentiate them so let me try  to explain it. Informative Documents are basically documents where you talk about the domain and everything involving it (like partners, place, the scope, etc) without necessarily going into detail about the technical stuff involved in your domain. In an informative document you can find the following: Descriptive Documents ...
