Business and Management is pure Science

Management, Marketing and Business development is known as Arts and as well as Science. If we go through the famous writers' books we may get this discussion in their books. But what I like to express that the model of business is changed completely. Now a days Business development is practicing in different organizations same as science. Here business is practiced as some instructions those are already set up to achieve the goal. Which is the definition of "Algorithm". A set of function to archive an object. Most interestingly these instructions are followed step by step. All these steps are followed in a order. 1st step 1st; 2nd step 2nd. If any one gives the 2nd step 1st he will finish with no result. This is the process which is known as Relational Database Management System (RDBMS). This is a process that is followed by IT engineers for a particular problems to solve; such as a software solution. So In this aspect it's proved that sales, marketing and management are pure science. Actually what I think from the very beginning of civilization, the generation of thinking people came 1st. Their job was thinking all the day looking at the sky by opening their mouth. And give the anti-logic of any illogical sayings and thought of society. They were known as the 1st generation of the world. After them the 2nd generation came with the thought that people should acquire knowledge and religion should be the part of our daily life as there are lots of things to learn from religion in other way from almighty/creator. These people were blessed and known as Prophets and other religious people. A time came and Almighty sent one blessed person who declare the end of the prophets and religious people. He was the greatest prophet Hazrat Md. (Sm.) After him the 3rd generation started to came. They were the scientist as Newton, Einstein, Tomas Alva edission etc. Writer as HG Wells, Alexender Damus etc. Painter, carpenter etc. All of them were the blessed persons. Which means the knowledge got more depth. It became the science of some knowledge. Such as IT, Physics,Chemistry, Maths etc. Now the goal of every arts subjects are to the science. I have a question does any one has any Idea who will be the 4th generation??? What will be their task???
