MYSQL Introduction:
What is SQL?
SQL stands for “Structured Query Language” and can be pronounced as “SQL” or “sequel – (Structured English Query Language)”. Defined, SQL is a query language used for accessing and modifying information in one or more data tables and rows of a database.SQL Database Design
IBM first developed SQL in 1970s. Also it is an ANSI/ISO standard. It has become a Standard Universal Language used by most of the relational database management systems (RDBMS). Some of the RDBMS systems are: Oracle, Microsoft SQL server, Sybase etc.
Most of these have provided their own implementation extensions, thus enhancing their RDBMS system features and making it a powerful tool. These RDBMS systems, all use the popular SQL commands SELECT, UPDATE, DELETE, INSERT, WHERE in similar format.
SQL Database Table
SQL database is constructed of a number of tables. In a business, SQL tables would be used to divide and simplify the different areas of the operation: Table for Customers, one for Vendors, Employees and so on.
SQL Database Table Columns
Each SQL table is made up of a number of columns, referred to as fields and run along the top of the table. Sql columns or fields have their content (object/data/info) defined into character types; such as text, date, numeric, integer, length to name a few.
SQL Database Table Rows
Each SQL table row, referred to a record, is located in the left column of the table. Sql record row will contain a string of data containing data matching up to each column field across the top. So, in a "Customer table" each "customer record" would consist of one row with data for the customer ID number, customer name, address, phone ...email and so on.
SQL Commands: Few SQL Coding Statements?
Few of the Sql commands used in Sql code programming are: SELECT Statement, UPDATE Statement, INSERT INTO Statement, DELETE Statement, WHERE Clause, ORDER BY Clause, SQL GROUP BY Clause, Subquery Clauses, Joins, Views, GROUP Functions, Indexes etc.

store data
modify data
retrieve data
modify data
delete data
create tables and other database objects
delete data
