Now, when we look at the above definition in a broader sense, a constructor is a class method that gets automatically executed whenever class’s object is created or whenever class is initialized.   Consider following bit of code: public class MsDotNetHeaven     {         public MsDotNetHeaven()          {               //A default Constructor          }       //Class members     } In the above snippet, the method MsDotNetHeaven() is called the constructor of class MsDotNetHeaven, also called default constructor.

Relational databases like SQL Server use indexes to find data quickly when a query is processed. Creating and removing indexes from a database schema will rarely result in changes to an application's code; indexes operate 'behind the scenes' in support of the database engine.

For example, one way to find all references to INSERT statements in a SQL book would be to begin on page one and scan each page of the book. We could mark each time we find the word INSERT until we reach the end of the book. This approach is pretty time consuming and laborious. Alternately, we can also use the index in the back of the book to find a page number for each occurrence of the INSERT statements. This approach produces the same results as above, but with tremendous savings in time. When a SQL Server has ...
