Database Tutorial |
A database is a collection of data, organized into columns and rows(records). Organizing the data helps in easy and speedy retreival of data by the users. Users can also enter data, modify already present data, query(request) database for outputing required information.
For example- There are thousands of books in a library. If you wish to find a certain book, it will take you days to look through every shelf in the library. Thus the data about books and their shelf locations are stored with the librarian. Books are organized by authors, alphabetical order, shelf no. etc and information can be found in much lesser time. This organized collection of data is called a database.
Earlier libraries used paper based databases where information was stored on paper cards. Modern libraries use computerized databases which make the process of finding and updating information faster and more accurate.
