Chapter 2. Looking more closely at queries

After completing the chapter, you’ll be able to

The most natural act when you have a data store of some type is to ask it a question. This activity doesn’t necessarily require a database. Knowledgeable people are asked lots of questions by those who want to know something. Someone long ago decided to call this activity a query when it comes to computers, but the concept is precisely the same. When you store data with a computer, you want to be able to ask the computer questions about that data later—otherwise, the data is useless. That’s what this chapter is about—asking the computer questions to gain information ...
