How are database used in the real world?

Answer 1

Perhaps one of the simplest examples of everyday use of a database is an address book.

A more complex example is a shopping list, or a combined shopping/to do list.

You mentally run through the items you use on a daily or weekly basis, consider those you might be running out of, or have run out of, and write them on your list.

Then you might think of items you rarely use but which are now needed and add those to the list.

In another part of the list you could write down things you need to do while you're out shopping, such as mailing postal items, paying bills, dropping off drycleaning, meeting a friend, and so on.

In still another part of the list you'd maybe jot down items you'll order by telephone or online and people you need to contact by phone or email, tradesmen, for example.

Then, with database complete, you set off on your shopping trip.

If you're well-organized you'll cross out (delete) data as each item is accomplished or purchased. You might move out-of-stock goods to your phone/online order list.

Arriving home you store your purchases, make a coffee, and sit down with another everyday database - your address book - to take care of phone and online orders, ask the plumber to call tomorrow, catch up with friends.

You create a new database listing anything left to be done from your original list and discard (delete) your now finished shopping list.

Then you update your address book, adding or removing data as necessary.

That basically covers creating, using and maintaining databases.
