Query Clause Indexing
Are the World Governments (Politicians) not spending money and borrowing money because of Global Indian Computing Standards?
Imagine being able to index any CLAUSE of the SQL Query...
I am not able to patent this as I have no Time and Money and on top of that no reply from Indian Patent Officers.
The Query Clause Indexing can UNITE the WORLD for a Cause.

SEMI-JOIN A Beautifully Architected Algorithm by TIBCO.
An algorithm that is so amazing and felt like a hack in Data Virtualization.
A query in the clinical trials data of Astra Zeneca was taking around 2 hours to execute and a lot of caching errors.
It was called the clinical trials hub and I was tasked to optimize it. Semi-Join, Multi Table cache refresh along with drop and recreate indexes, the execution time of the refresh was 2 Minutes.
20 seconds - Execution of Query.
The rest of time - Insertion.
I was amazed because it had been long time since I got my head to work again but something kept running in my mind.
What if I would like to build something superior than the semi-join?
I would have to keep thinking for ever.
When there are two tables that are to be joined from Two Different Databases (Different DB Servers), SEMI-JOIN will convert the parent query in such a way the IN CLAUSE is re-written and the FETCH happens from a Single DataBase Server. I do not need to explain more as a person familiar with SQL will understand how this JOIN Algorithm works.
