SQL is sands for Structure Query Language 
. 
SQL has many definition but we take some 
of them 
SQL is special purpose programming 
language designed for managing database. 
On other hand 
SQL is rational database language.
 Can be used to create function and trigger 
procedures. 
 You can add control structure to the SQL 
 Also you can perform complex computation 
 SQL can be used to retrieve large amount of 
records from database quickly and 
efficiently
 Difficult in interfacing 
More features implemented in proprietary 
way 
 SQL is invented primarily to provide a 
method to access structure data in order to 
transparencies the physical storage scheme.
 IBM invented a computer language back in the 1970s 
designed specifically for database queries 
called SEQUEL, which stood for Structured English 
Query Language. 
 IBM released SEQUEL into the public domain, where 
it became known as SQL. Because of this heritage you 
can pronounce it as "sequel" or spell it out as "S-Q-L" 
when talking about it. 
 Microsoft initially developed SQL Server (a database 
product that understands the SQL language) with 
Sybase Corporation for use on the IBM OS/2 platform.
Data Manipulation 
Data Definition 
Data Administration 
All are expressed as an SQL 
statement.
 When we start SQL codes always first code is create 
 Database ,Table and so on….. 
 Just write in area of work 
 Create Hospital 
That is database 
Create Table 
( 
Employee ID integer , 
Employee Name varchar(50) 
) we use codes like that.
