Give three examples of databases that you often come into contact with? What information do they store?
Google, for finding specific things and sites.
Wikipedia, to find specific things about people or groups.
Ebay, to buy items and find information about said items.

When developing databases, why must security be a major consideration?
Because some databases could have really important/private information stored which anyone could obtain and use. Things like identity theft is one problem that can be caused by low security of databases.

Is it important to consider confidentiality in determining who can access some databases?
Well, as stated before, depending on who uses it and what kind of database it is, you need to have some confidentiality/security so no one gets screwed over.
