CS343-01: Week One Blog

Software Constr – Week One

For week one’s blog, I read the article I first found, Software Architecture Recommendations By Mark Richards. I wanted to start off with something I’ve found first before potentially either diving into more research for videos and articles or maybe even going through what my classmates have found for inspiration.

In Software Architecture Recommendations By Mark Richards, it features a software architect named Mark Richards who covers his definition of software architecture along with the key soft skills and responsibilities of an architect. There are two aspects of software architecture in his vision, as structure and as process. “Within the structural aspect of software architecture there are 4 dimensions: architecture characteristics, architecture components, architecture styles, and architecture decisions.” He mentions how there are soft skills and techniques which include negotiation, facilitation, and leadership when it comes to the process aspect he sees in software architecture.

He says that negotiation is a required skill since “almost every decision you make as an architect will be challenged. Your decisions will be challenged by other architects who think they have a better approach than you do; your decisions will be challenged by business stakeholders because they think your decision takes too long to implement or is too expensive or is not aligned with the business goals; and finally, your decisions will be challenged by development teams who believe they have a better solution.” Which makes sense since if you want to do your job, people will think what they have to say is better, more efficient, etc. So you do have to understand the political climate– as the article says– and how to navigate it to get the views and decisions you made both approved and accepted.

Facilitation is another “soft skill” that Mark Richards thought of where the architects don’t only collaborate with development teams. He says that they should also collaborate with various business stakeholders to understand a number of things such as “business drivers, explain important architecture characteristics, describe architectural solutions, and so on.” Upon further research, I found that facilitation is a shift in the architect’s role from a central decision-maker to a facilitator who empowers the development team to make architectural decisions collaboratively, so it’s a tool to have to keep things on track.

And then there’s leadership. The architect in Mark Richards’ mind is responsible for leading and guiding the development team through implementations. “They are there as a guide, mentor, coach, and facilitator to make sure the team is on track and is running as smooth as a well-oiled machine, and to be there when the team needs clarification or has questions and concerns about the architecture.”

Reading this from his perspective and his opinions are an interesting way of learning his job as a software architect since he has the experience and he has learned from the mistakes he’s made. It’s an important thing to know that even though it’s his job, he’s always learning about ways to improve and for him to share this knowledge is something that’s valuable since you can take the advice and knowledge given and apply it to your own job.

CS343-01: Software Constr, Des & Archit

Software Constr – First Steps

This is the beginning of my documentation in my class CS-343 and phase two, part two, I suppose, for CS@Worcester with the work that I was able to accomplish, had trouble with, and solutions I found.It’s kind of like my last and now current blog, except new class equals new puzzles I’ll experience! I really hope to do well, even with quizzes or exams as a sort of weak spot for me.But hopefully, with enough reading and practicing, I’ll do well. I want to do well. I’m aiming to do well.

UML Class Diagram Arrows

Seeing how one of my CS classes just recently introduced me to UML class diagrams, I wanted to conduct some research on the formation and comprehension of the diagrams. I looked for blog posts that showed examples of the diagrams and how they would be written, since I like reading written explanations and visual representations.

I stumbled across a blog covering the different arrows used in the diagrams, as well as when and how they can be used. That blog can be accessed at https://www.gleek.io/blog/class-diagram-arrows.html.

The blog presents to us six different types of class diagram arrows: directed association, inheritance, composition, realization/implementation, aggregation, and dependency. I had already seen directed association, inheritance, and implementation arrows, but I had not yet familiarized myself with the others. I learned the following from the blog:

A composition arrow in a UML diagram does not have an actual arrowhead, but instead looks like a solid diamond at the end of a solid line. The solid diamond is at the sub-object end of the solid line, and indicates that the sub-object cannot exist without the container class. It can be shown using -<*>.

The aggregation arrow looks just like the composition arrow, except that the diamond is hollow/white. The aggregation arrow is used to show association between two classes, but the subclass can still exist without the super class. It is shown with -<>.

Dependency arrows have a thin arrowhead and a dashed line. They show that two elements depend on each other but the dependency is weaker than standard association. Making changes to the parent class will have an impact on the child class. It is shown with -.->.

This blog was a great source to understand the usage of different arrows for UML diagrams. It provided great examples of when to use aggregation and composition, and I now know to take those into account for when I will need to make my own UML class diagrams in the future. It was easy to understand how the relationship between a library class and a book class can use the aggregation arrow because books can still exist after they are borrowed from the library. It was also easy to see how the relationship between a shirt class and pocket class can be composition association because a shirt pocket would not exist without the shirt. I also think it was a nice touch for the blog to include a video on the page where it explains the arrows and shows how the examples would be typed up on gleek.io.
