In the article I read, it spoke about often intimidating size of most databases. There is an urgency in the article to make sure the user has a grasp of what there is to work with and to make it easier. In order to help the user, a 3-D model has been designed. It is designed to help give a visual perspective to the user. This will help the user to understand the specific database at hand. With a method like this, it would be very useful for beginners. The model is composed of the top view, the front view, and data flow modeling. All of this gives the 3-D view. The article explains about how rows and columns are distinguished and how the relationships between each entity are identified. The top view looks much like an entity relationship diagram. The front view enables the user to compare the different tables and their sizes. Data flow on this type of data modeling is heavily relied upon colors and contrasting. Dotted lined between tables with a diamond in between signify a many to many relationship. The whole purpose of 3-D data modeling is to use the screen to actually aid the user in their perception of the database.
In class we spoke about how important it is to show the relationships between entities. Correctly showing these relationships aid in making the database more efficient and helps with making sure there is less duplication. This helps the business run better and pull/put the information in/out of the correct table. Design is a fundamental aspect of data modeling and this particular approach helps accomplish that with visual aid.
I found this article to be particularly interesting. It spoke often about visual perceptions of databases. However unique this approach is, I feel it would be more of a learning tool in a classroom for students to see what they are learning. Once students have the image in their minds, it is much easier to move on from the visual basics. This would turn the 3-D modeling into a reference. It was a good article to read and I am glad people are still thinking outside the box.
