Data modeling is a vital aspect of database creation and management. The ER diagrams lay the logical framework for an entire system, upon which so many people and other systems will be relying. Fundamentals, as with every other academia subject, are a complete necessity. Luckily, articles such as this one exist which aid in understanding. It outlines the basics of modeling which we have also touched on in class. It covers a variety of styles, patterns, and classifications of ER diagrams which may be used in the modeling process.
As I stated prior, data modeling will play a presumably very important role in this class. In order to successfully set up a fully functional (and hopefully unique) database system, we are going to have to utilize the foundational knowledge articles to manipulate such models to create something new for our respective fields. The value of teaching resources can never be understated, regardless of their source (unless, of course, it’s unreliable). We pay good money to attend classes at Cal Poly and there are many in the industry who pay good money to attend lectures and programs in which they teach these types of concepts.
From a personal standpoint, I presume I am not alone when I state how crucial these types of documents are to our education. I (we) have so much to learn regarding all of these methodologies and I welcome any and all sources of information for data organization. Getting various perspectives on any given subject is very rarely detrimental to the learning process and we should certainly be embracing that.
