Kosmik is the best place to learn sql server. I have learn sql server from kosmik. It's been a long journey with them until we get the satisfaction. Srinivas jagarlamudi is a best faculty member in kosmic for sql server. He is more friendly and he will teach the classes with his real time work at classroom. Moreover the administration team was awesome in order to full fill the student requirements. I am strongly suggesting anyone looking for sql take step at kosmik. Thank-you kosmik.
