Finalizing the work.
First Create a database in your server and import sql.sql file (at the root folder) to your database. Please truncate settings and crawl talbes. Anyway do not delete administrator user from admin table. .
Now change the database connection file at "Connections/saha.php" as follows
$hostname_saha = "yourhost";
$database_saha = "yourdbname";
$username_saha = "yourdbusername";
$password_saha = "yourdbpassword";
Please note that user password can change from the script and you need to change passwords using admin area. .
