XML datatype first introduce in SQL SERVER 2005 as a column and it has a lots of benefits and implementation in today's environment. There are some restrictions in defining xml as a data type but still it has a huge benefits for large objects and complex structures like student information history, patient history in hospital management, logical comparison of properties in Property based database and CV detail of employees on any CV site. All of above have huge data to store but very little to update only thing required is to compare and return.
I have assigned task to optimize a table for its DML and
reading operation and this table has XML column in int. I am not a beginner in
xml implementation but I have assigned task to optimized it first time in last
5 years so this was quite a good task for me I have searched for it and
complete this task by improving around 75% time. During this process I have
learned many new things and I want to share it from start till end step by step.

my environment and also using following links
