What is business logic in SQL?
Business logic is supposed to be the part of the application where you deal with customer or user facing decisions and computations. It is often argued that this part should be well separated from the rest of the technical infrastructure of your code.
How are business rules stored in a database?

Most other web development alternatives like ASP.NET, JSP, Spring use a multi-threaded processing architecture to cater to concurrent client requests.
