Database is a separate application that stores a collection of data. Each database has one or more distinct API’s for creating, accessing, managing, searching and replicating the data that it holds. And a relational database management system is a database management software which enables one to implement database with tables, columns and indexes. It can update the indexes automatically. It interprets an SQL query and combines information from various tables.

A My SQL database management system contains the following items:

Database:

Database is a collection of tables with related data.

Table:

Table is a matrix with data. It is like a spreadsheet in database.

Column:

Column contains the data.

Rows:

Row is a group of related data.

Primary key:

A primary key is a unique key that cannot be applied twice in the same table. It is the specific key which will specify the unique identity of similar items.

Foreign key:

It is the key which establishes the relationship between two tables.

Index:

Index is the resemblance of indexes in a book.

Compound key:

It is the key that consists of multiple columns.

The MySQL queries are the basic players of data manipulation, data definition in database. Queries are used to store data, delete data, update data and many more purposes. These queries send the user information to the database and retrieve the same data for display. The queries are the main components of playing with data. Without these queries the interaction with user is impossible. Billions of user information are stored on databases using these queries. Insertion to deletion, retrieval to update everything is performed by the SQL queries. Queries are the running force for data. A query includes a list of columns to include the final result following the select keyword. Select is the most complex statement in SQL. Some other clauses do optional works with data.

My SQL works very well in combination with various programming languages. PHP is the most popular language where SQL queries are used for web application. PHP provides various functions to access MySQL database. General form of PHP function in MySQL is as follows: Mysql_function (value, value, value…);

There are basic three functions to be used before inserting data to database. Database creation: The PHP function for database creation is: Mysql_query (sql, connection); The PHP function for database connection is: Mysql_connect ($connect); The PHP function for selecting database is: Mysql_select_db (db_name, connection); User interfaces of MySQL: Graphical user interface: Graphical user interface is a type of interface that allows user to interact with the device through graphical icons. Graphical user interfaces are easy to learn than the command line interfaces.
