Whereas Netezza will be completely new to us. Personally, I would like to stick with SQL Server as I am very familiar with it, Netezza server is basically an analytics system and provides many useful functions that can perform day to day aggregations. A Netezza SQL analytic function works on the group of rows and ignores the NULL in the dat. It comes with its own ETL tool (Data Services) and Reporting tool (Cognos), which is an added advantage.Īnd we are going to start our POC on SQL Server 2014 in-memory in next few weeks and going with 12 core CPU as a starting point, so that the cost is similar to Netezza. Netezza analytic functions compute an aggregate value that is based on a group of rows. Though it has few drawbacks like not being able to use scalar/table value functions, some unsupported data types, etc., the product has alternative ways of getting them to work. We just finished our POC on IBM's netezza and its performance is simply amazing. New areas/technologies that will provide us better performance and have started doing a POC on IBM's Netezza and SQL Server 2014 in-Memory technology. We are currently using SQL Server 2008/2012 server for our reporting purpose and our queries takes long time to execute because of the amount of data in the database and also because of the way some queries are written.

Learn about the terminology Microsoft uses to describe software updates. Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. Throughout this blog, the term SQL refers to Netezzas SQL implementation. Netezza SQL is the Netezza Structured Query Language (SQL), which runs on the Netezza data warehouse appliance. SQL Server is the Microsoft-driven relational database management system. It has the same key design tenets of simplicity, speed, scalability and analytics power that was fundamental to Netezza appliances.

Everything after this line is an OLE DB initstring IBM is fully committed to ensure that every single one of our Netezza clients migrates successfully to IIAS or Db2 Warehouse on Cloud or any form factor in the Common SQL Engine of the Hybrid Data. SQL is pretty similar, but Netezza may have different function to accomplish the same thing compared to SQL Server.
When you specify a DB2 SET special register statement for OLE DB Provider for DB2, you should delimit the special registers argument by using double quotation marks around the value (Special Registers="SET CURRENT QUERY ACCELERATION=ALL"). The Microsoft Data Provider for DB2 and related configuration tools are updated in this update to expose a new special registers connection property. From sql 2014 onwards you can use in-memory OLTP feature. In your SQL server how well tuned and optimised are your databases, tables, procedures etc. To process the required SET CURRENT QUERY ACCELERATION special registers statement for DB2, the Microsoft DRDA Application Requester runtime library was updated to support the DRDA EXCSQLSET (Set SQL Environment) and SQLSTT (SQL Statement) protocol code points. If you compare the performance of SQL server over netezza and if you get better results I did not see any reason why you should not move just based on performance. This statement is required when you connect to the IBM Netezza data warehouse appliance or to the IDAA (IBM DB2 Analytics Accelerator). The Data Providers for DB2 do not currently support specifying the SET CURRENT QUERY ACCELERATION special registers statement.
