Databases (DB’s) are structured collections of records or data that
are stored in a computer system. The Internet itself is a vast DB!
Online DB’s are typically very large and are created by trusted
experts.
Some are free, like Wikipedia. Most are fee-based and can be very
expensive, such as LexisNexis. This type is commonly used by
specialists like attorneys or physicians.
You get what you pay for! Fee-based DB’s are more likely to be
reliable. In this presentation we’ll be referring only to fee-based
DB’s. Free info is fine but we want to be assured of accuracy.

Most DB’s work similarly. When you learn how to
use one the others will work about the same way.
You usually need a password to login since the
user (or a company) pays a fee to access the
records.
Complicated DB’s will have a Users’ Guide or a
Help menu to get you started.
The rules of DB searching follow basic Boolean
logic. Click here for more info: Boolean Searching
