2. What is a database?
A database is a collection of organized tables. Each table is a collection of related records.
Each record gives information about one item and is made up of many fields. Each field is one specific piece of information.

3. Our world depends on databases

Facebook is build around databases
So is e-Bay & Netflix and X-Box Live
Travel agents, schools, doctors and hospitals all rely on them
You get the idea!

4. Databases are so useful because they’re so good at storing info
But they do it in a very structured way
That’s so the data can also be sorted
And so the data can also be searched
So overall, what makes databases so useful is how they store, sort & search
Let’s look at some examples…
