designing your database and ActiveRecord entities In most cases this is not the correct way to write code. Of course it might work in some cases, but as a "default schema" It's not what you want. Why did you make any technical choices before we even understood the problem areas? This is simply putting the cart before the horse.Microsoft's ecosystem encourages everyone to use SQL Server.

After at least 4 years of intense debate, it is time to make a phased conclusion about the status quo of NoSQL. So many things have happened around NoSQL that it is difficult to make a simple generalization, and it is difficult to judge what it achieves and what it does not expect. In many areas, NoSQL has not only been successful in the academic field but also in the industry. The university began to realize that NoSQL had to be included in the curriculum. Just repeating the standard database
