What are the uses of a Database?

Answer 1

They're for the efficient, organised storage and retrieval of data. Any depository of information can be described as a "database" but what most people mean when they say "database" is a "relational database" - a series of data tables linked to each other. Data organised in this way is enormously powerful as one can begin to "query" a database for a huge range of information which may not be immediately evident when stored in a "non-relational" format. For example, businesses can identify their most lucrative customers; their top salespeople in a particular city; any late payers; inventory levels etc.

In fact, it's hard to think of an area of our lives which isn't touched by databases: banking; taxes; travel; sports events; all major websites; telecommunications; transport; healthcare; retail... the list goes on.

Personally, I find database design one of the more rewarding aspects of IT. It's quite satisfying to be able to take unorganised data and organise it into useful information.

Answer 2

Let's say you want to keep track of customers. But you have 1000s of customers. Well a database willl allow you to list, store, organize all those customers...and then you can retrieve the information and sort it by address, city, phone number, order number...etc etc. Many uses.
