It is publicly known fact that RDBMSs have well known limitations when it comes to unstructured data management. This is the reason to emerged new database technologies like NoSQL. It is true that NoSQL is not a replacement for RDBMS. However the time has come to include NoSQL features into RDBMS products (then it can’t be called it as RDBMS) or introduce brand new NoSQL product from RDBMS vendors. We need to wait and see how Microsoft react to these new technology trends and how SQL Server change accordingly. Oracle has already announced their NoSQL version called Oracle NoSQL Database. Will Microsoft come up with new NoSQL product?

What is 24x7? In simple terms, it refers to “Always On” or “100 % availability”. Meaning the information system is available to users, at any time, without interruption. No matter what the day is. No matter from where users access the system is.
Web definition of 24x7 is stated below;
“24/7 is an abbreviation which stands for "24 hours a day, 7 days a week", usually referring to a business or service available at all times without interruption.” 
The most popular and the technical term used for the same concept is “availability”. As we learn in our software engineering subject at graduate studies, “availability” is one of the non-functional requirements of an information system. To achieve 24x7 availability, an enterprise has to spend money on it. It does not come free, as many end users may think; in long run enterprises get the return on 24x7.
