The 4+1 View Model

Today I will talk about the resources related to The 4+1 View Model, two Youtube videos and one article named The Elephant and the Blind Programmers by Grady Booch.
These videos and article speak briefly about the 4 + 1 view model, this small model consists of four sections and an additional section that is part +1, which allows us to make a better software architecture. Let me explain these views:

- Logical view: This view tells us what kind of objects we are going to build, how they communicate and what kind of data they are.
- Development view: It is useful for developers to always know which part is related to what else and how things are organized during development.
- Process view: describes the concurrency and synchronized aspects in the software and the process of using the software or doing things.
- Physical view: It tells us how the software and the hardware are related.
- Use cases or scenarios (+1): They are the explanation on how the system is expected to behave, what should happen and how users are supposed to use the system.

In a software engineering project, we have a lot of information, so it is important to view this information from different perspectives to understand clearly what the system should do.

The other video is about a fable from India that illustrates the inability of man to know the absolute truth. In the article, Grady Booch takes as his basis the same fable to tell us the story of five blind programmers who meet a beast and when examining it, each one has a different point of view that claims to be the correct one without even considering the points of view of the other programmers.

Hidden Figures

Today I will talk about the amazing movie titled “Hidden Figures”. Normally in those times they didn’t recognize all the women were part of important projects and this movie is one example of how they used to hide the work from the matchless Katherine Johnson. I can say that it has become one of my favorite movies.     The film tells the story of three African-American women who worked for NASA in the early 1960s, collaborating in an important space program. These brilliant women achieved incredible goals that seemed impossible because they were women and African-Americans.     What impresses me about these women is their intelligence, their strength, their perseverance and their struggle that allowed them to demonstrate that they were more than capable of being involved in areas that were considered suitable only for the masculine intellect, such as science, mathematics and engineering.     I can identify a little with those great women of that movie, not because of how brilliant t

Understanding the SOLID Principles

Today I will talk about the Edward Guiness’ book section titled “Understanding the SOLID Principles”. First of all Solid is an acronym that stands for five principles of object-oriented programming and design. These principles help to avoid dependencies between the classes. S-Single Responsibility Principle O-Open/Closed Principle L-Liskov Substitution Principle I- Interface Segregation Principle D-Dependency Inversion Principle Talking a bit more of these principles we are going to explain each one: Single Responsibility Principle: This principle states that one class should only have one responsibility so the changes in that class do not end up affecting unrelated critical features on the system. This happens from a single action to a set of processes. You can take a view that a single responsibility refers to a group of related business processes. The stamina and tolerance determine how far you go Open/closed Principle: This principle talks about that classes should be op
