3. Searching the database to find specific information is called a
query.
4. Why are we concerned about electronic databases?
-Because we use them more and more nowadays.
5. Explain 3 different types of S/E issues related to online databases.
-Security: Maybe it isn't safe to have your info where people can have access to it.
-Control: Other people control these databases.
-Equality of Access: Not just anyone can have access to these databases, but if certain people do, it can affect you negatively.

presentations/essays notes
Privacy of info in diff cultures
Information you put of yourself on the internet isn't always "safe"
It can harm us. In China, the information of someone who uses the internet is kept for 60 days (information like: address, phone number, ID, etc.)
Rights of Indivdual w/respect to storage of personal data
Social consequences of release of sensitive data stored in databases
you can be mistaken for another person, and be accused/assaulted. All anyone has to do is take ur hard drive to steal your data.
Ethical Issues related to selling data
Paper Files vs Electronic Files
Elec. files are used more in businesses. Electronic files are easier to use for searching files. All you have to do is query info wanted instead of going one-by-one to find it. It allows more than one person to look at one copy of a database, unlike paper, because there would be only one copy. People can be across the globe and still see the same thing as someone somewhere else. Nothing can be deleted unless you take it off the hard drive itself, whereas with paper, you just need to burn or shred it to get rid of it completely.
Responsibilities for security of data
Social Consequences of outdated or incorrect info on databases
If a database has incorrect info about you, if they want to send you something, someone else would get it. If they have the wrong info, and they get someone else's identity, you will get information and spam, ads from those people that have nothing to do with you. It all belongs to someone else. You won't get the services that you need. Other people might get it instead.
