Description
Welcome to the course Database Management system from scratch !!!Mastering the concepts of Database Management System is very important to get started with Computer Science because Database Management System is the program which is responsible for the ease with which we are able to fetch the data from the database and that is the backbone of internet today. The concepts which we are going to study is going to give a very good understanding of Database Management System and by the end of it you will be able to answer any interview question on Database Management System.Without using Database Management Systems ,it is extremely difficult to communicate with the data in the server. Every server today has Database Management System installed in it. Through this course you will not only master the basics of Database Management Systems but also get ready for venturing into advanced concepts of Database Management Systems.In this course ,every concept of Database Management System is taught in an easy-to-understand manner such that anybody without any prerequisites will be able to master the concepts of Database Management System in the easiest way.Come and join me, I assure you that you will have the best learning experience of not just Database Management Systems but also the core of Computer Science in a different dimension.
