A Database is a collection of data well organized in such a way that it can be accessed easily and efficiently.
It seems very easy to define. But this is the one which rules the entire world in any field.
Our entire life a database and the daily activities involve lot of databases. Even the list of your Boyfriend/Girlfriend’s is also a database 😉
It can be physical (paper) or electronic. But in this fast growing world, most of the people are using electronic only. i.e. which are stored in computers.
- List of employees in an organization
- Contacts in our mobile phones
- List of account holders in bank records etc….
Data can be of any kind. It can be related to educational institutions, organizations, banks etc….Please do not think that DB contains only numbers and text. It can be anything like songs, movies, images etc…Nowadays people prefer electronic DBs as they are more secured and efficient than the DBs in physical form. Because anyone can open and read the data which is in physical form. But in electronic DBs, we can give access to the limited number of people who have rights to access the data.
If you have already heard about DBMS (Database Management System), do not be confused between Database & DBMS. Database is just a part of DBMS.
The name itself is saying that, it is the system which manages different databases. We can say it is an Engine which drives the databases.
It allows us to store, modify and extract data from a database.
- SQL Server
- Sybase etc.…
Types of DBMS
There are five types of DBMS.
Any technology in this world should depend on database. Other technologies are just like human beings visible to the world as applications, user interfaces etc…. But we are like God who is driving/Ruling them from back end. Proud to be Database developer 😎
