At first when you hear the question of “Why Databases” you might think why should I learn about databases? If this is your question then you have likely answered it already. The answer is it pays very well and leads to a great career. Going deeper into the question is why do companies need databases so much they offer you such a career? The simple answer is there is a high business need for databases and SQL is a very powerful and affordable enterprise database management system. What does that mean exactly? In this lecture we will talk about the business needs for databases and how SQL Server is a complete system used to manage these databases.
