Hour 2

Exploring the Components of the SQL Language

What You’ll Learn in This Hour:

  •    An introduction to and brief history of SQL

  •    An overview of the SQL standard

  •    An introduction to some vendor implementations of SQL

  •    The basic components, or sublanguages, that comprise the SQL language

SQL has many components that are simple yet offer flexibility and power for any user communicating with a relational database. This hour provides a broad overview of SQL, to cover some preliminary concepts that you need to know before you jump into hands-on exercises and coding. Be patient with this hour; the “boring” background material helps you build a solid starting foundation.
