Introduction to database:

The name indicates what the database is.A database is one of the essential components for many applications and is used for storing a series of data in a single set. In other words,it is a group/package of information that is put in order so that it can be easily accessed manage and update.

There are different types of databases. They are

• Bibliographic
• Full-text
• Numeric
• Images

In a database even the smallest portion of information becomes the data.

For example,a Saudi football league player is a data ,name is a data ,and the age is data,position, height,weight marks everything in data.In brief,all the living and non-living objects in this world are data.

one of the primary aims of a database is to supply users with an abstract view of data,hiding a certain element of how data is stored and manipulated. Therefore,the starting point for the design of a database should be an abstract and general description of the information of the Organization that is to be represented in the database. And hence you will require environment to store data and make it work as a database .
