Chapter 0. Access Basics
If you’re already an Access ace, you can skip this chapter and move right into the meat of the book. But if you’re still clawing your way up the learning curve, here’s a brief overview of some basic Access concepts and procedures.

A list of the object types in your database appears on the left side of the window. You can click an object name to show objects of that type (of course, there won’t be any until you create some). The key types of objects are:
- Tables
Tables are where data gets stored. A table in Access is roughly analogous to a table in Word or a worksheet in Excel—column headings (a.k.a. fields) and rows (a.k.a. records) are the main structural elements. The difference is that in a database, you must define these structures much more precisely. This is the foundation on which everything else rests. (See “Table Design 101” in Chapter 3 for more info.)
- Queries
Queries which are based on Structured Query Language (SQL) typically retrieve selected data from tables. They can also be used to modify or delete existing data, add new data, and create new tables.
