What is a database?
Surely, a dictionary would supply us a good definition of a database. From Merriam Webster Dictionary, their online definition of a database states : "a usually large collection of data organized especially for rapid search and retrieval (as by a computer)". A longer description from its accompanying Concise Encyclopedia explains that a database is an organized collection of data or information that is structurally stored to make retrieval easy for users.
Each database follow a system of data-processing operations which keep data on files that can be divided into records which "consists of one or more fields. Fields are the basic units of data storage. Users retrieve database information primarily through queries. Using keywords and sorting commands, users can rapidly search, rearrange, group, and select the field in many records to retrieve or create reports on particular aggregates of data according to the rules of the data management syestem being used."
If this sounds too complex we have illustrations (see below) for you in this guide to clear your database concepts; so keep on reading.
Take a good look at your cell phone. Look at what happens when you add a new contact or a new friend's number on the list of contacts. The cell phone provides you with boxes similar to this:
When you enter your friend's name and other information in the fields provided, you are entering a record in the database which exist in your cell phone.When the phone rings, it identifies the caller because it matches the record and the field.
Your cellphone may display your database listing as follows.
