MongoDB to the Windows Azure cloud

In my previous post, it is mentioned the need of NoSQL product from Microsoft. I did some Googling and found several interesting posts where Microsoft and 10gen (one of the famous document oriented database vendors who invented MongoDB) has come to a collaboration to bring MongoDB to the Windows Azure cloud. Below are the links found related to Microsoft and MongoDB.

Future versions of SQL Server?

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?

In this I got to know about deprecated memory feature used in SQL Server 2008 R2 and previous versions. That is “AWE Enable” option. This feature is no more in SQL Server 2012. I found below posts on SQL Server memory and thought of sharing.
