Why Databases?

The only place you’ll get “free” information is the library.

Did You Know?

The Web: Visible and “Invisible”

What’s The Difference?

• The Visible Web– Easily accessible by

conventional search engines• Google• Yahoo

– Mostly HTML Pages– Occasionally updated– STATIC

• The “Invisible” Web– Information is NOT

accessible through conventional search engines

– Database-driven– DYNAMIC

Why Should I Care?

(Why can’t I just use Google?)

Visible vs. “Invisible” Web

Documents in Billions

Visible = 1"Invisible" = 550

Visible vs. “Invisible” Web

Terrabytes of Information

Visible = 19"Invisible" = 7500

Why not Google?

• Popularity, not accuracy determines search results.

• No peer evaluation. • Impartial information? Not likely.• Reliable information? How would you know?• Google represents only a tiny fraction of the

information out there. “There ain’t no such thing as a free lunch.”

So, how do I access all this awesome, reliable information?

Welcome to the world of DATABASES.
