What is an Online 
Database

An online database is a collection of information which is stored and retrieved electronically in a networked evironment. It can be on a CD-ROM LAN, on the World Wide Web, or on some other manifestation of the Internet. This lesson will cover searching online databases mounted on the World Wide Web (also known as web databases), but the concepts can be applied to other online databases. For example, the Library Catalog is an online database, so if you have completed Lesson 3 some concepts in this lesson will already be familiar.

This lesson will not cover any database or search interface in particular, but will attempt to show you how online databases work and give you information you can apply to any search interface you encounter. This is important because there are many different search interfaces available and because they change frequently.
