Video Transcript

Speaker: In this course, I’ll introduce you to SQL and to the Relational Databases that SQL operates on. I’ll give you a little history so that you’ll see the context within which SQL was developed. People have been storing and using data for a long time, but it has only been relatively recently that they’ve been storing large quantities of data in an easily retrievable form. That easily retrievable form is the Relational Database.
