Lesson 1: Database Basics and Structured Query Language Chapter 1, Video 1: "Welcome to Introduction to SQL" Hi. I'm Cecelia Allison, and welcome to Introduction to SQL. In this course, you will gain a solid working knowledge of Structured Query Language. First, we will explore the basic structure of a relational database, and how Structured Query Language relates to the relational database structure. Then we'll dive right in and begin writing simple to more complex SQL statements. We'll write queries that create and populate tables, and queries that retrieve data from either a single table or multiple tables. We'll also write queries that manipulate data stored in the database, and queries that gather significant statistics from your data. Towards the end of the class, we'll look at some advanced querying techniques that assist in managing how your SQL statements execute. I'm looking forward to a great class. I'll see you there.
