Database Reference
In-Depth Information
The two chapters in Part 1 provide an introduction to database processing.
In Chapter 1, we consider the characteristics of databases and describe
important database applications. Chapter 1 discusses the various database
components, provides a survey of the knowledge you need to learn from
this text, and also summarizes the history of database processing.
You will start working with a database in Chapter 2 and use that data-
base to learn how to use Structured Query Language (SQL), a database-
processing language, to query database data. You will learn how to query
both single and multiple tables, and you will use SQL to investigate a
practical example—looking for patterns in stock market data. Together,
these two chapters will give you a sense of what databases are and how
they are processed.
