Slide 7: 

So what is a database?

Yes!

When you type words into a search engine, you are searching a very large database of websites Search Search the google database, please!

Slide 13: 

This database is updated automatically by a program that looks for new websites…

Slide 14: 

…and then describes them Title……………… URL……………… Year……………… Domain..…………

Slide 15: 

Because there are no quality controls governing websites… Title……………… URL……………… Year……………… Domain..…………

Slide 16: 

…the information is not always complete ?

Slide 17:
