Implementing in-memory capabilities to relational databases (SQL Server, Oracle, DB2 and others) used for data warehouses can dramatically speed up report execution. It takes less than a few hours to do so and, in our experience, does not require changes to existing models or reports.

1. Speed Tip: Apply In-Memory Capabilities

Senturus recommends to our clients that they implement in-memory capabilities in the relational databases they are
using for their data warehouses. By doing so, they can see some serious improvements in reporting response
time. It takes less than a few hours to do and, in our experience, requires no changes to existing models or reports.
Among our clients, SQL Server is the most common relational database and its in-memory capability is called
Columnstore Indexes. We implemented them in various situations and saw some report execution times drop from
6 minutes to an impressive 2 seconds. Recently, we executed them for an outdoor apparel retailer client and are
seeing sub-second response times with relational DMR package queries.
Columnstore Indexes are available in SQL Server 2012, 2014 and 2016. They are only available in the Enterprise
Edition. You can check the version and edition with these SQL statements:
SELECT
SERVERPROPERTY('ProductVersion') AS ProductVersion,
SERVERPROPERTY('Edition') AS Edition,
GO
Version Pattern SQL Product
12.0. x . x SQL Server 2014
11.0. x . x SQL Server 2012
10.50. x . x SQL Server 2008 R2
10.00. x . x SQL Server 2008
In DB2, the edition you’ll want is DB2 with BLU Acceleration.

2. In Oracle it’s an Enterprise Edition option called (surprisingly) Oracle Database In-Memory.
