Minimize Fragmentation

You can implement it simply when creating
table:
With (Data_Compression=ROW)

or after creating table:

Alter Table [Name] REBUILD
WITH(Data_Compression=ROW)

SQL Server 2008 R2 introduces the SQL
Server Utility for managing multiple
instances of the SQL Server Database
Engine.
In SQL Server Management Studio,
organizations will gain insights into their
growing applications and SQL Server
instances

Consolidation management
Use a new explorer in SQL Server
Management Studio to access the central
management for multi-server management and
at-a-glance dashboard views

Improve service levels
Set policies to define desired utilization
thresholds across target servers or applications
within a new central management point.
Identify issues with instances and applications

It also introduces a unit of management
called a data-tier application that provides
an application-based view for managing the
data-tier objects in the SQL Server Utility or
stand-alone instances of the Database
Engine.
R2 makes it easier for DBAs to move
databases around from server to server in
much the same way virtualization admins
move guest OS’s around between physical
hosts.

SQL Server 2008 R2 still has the same
concept of databases, but it’s added a new
level above databases called Data-Tier
Applications, abbreviated DAC

The DAC includes the database schema
plus some server-level objects required in
order to support the database, like logins.

The DAC does not include the data inside
your database.

For deployment best practices, you should
have any necessary data (configuration
tables, basic lookup tables) already scripted
out as part of your deployment strategy.

With the DAC approach, it makes sense to
put these scripts inside the database as
objects. For example, you might have a
stored procedure called usp_deploy that
populates all of the necessary configuration
tables via insert statements.

Developers create and update their
database schema, stored procedures,
functions, etc. inside Visual Studio,
packaging them into DAC Packs, and
handing them to the database administrator.

SQL Server installs by creating sysprep-ed
images of SQL Server standalone instances
that can be copied and quickly installed on
target systems.

Enables rapid provisioning and configuration
using prepared images stored in VHDMart
for Hyper-V deployments.

SQL Server 2008 Sysprep accomplishes the
install in two phases behind the scenes:
prepare and configure.

In SQL Server 2008 R2, two new SQL
Server setup actions are exposed to the
users: PrepareImage (also referred to as
“prepare”) and CompleteImage (also
referred to as “complete” or “configure”).

SQL Server PrepareImage takes about 30 minutes
for Engine and RS components, whereas
CompleteImage takes a few minutes.
Windows SysPrep process can be run in between
the two steps to create Windows OS image and
deploy to target computers, but is not a required
step.
These two steps can be run back-to-back on the
same computer. Sysprep will be able to save on
the average an estimated 30 minutes per install.

Master Data Services helps enterprises
standardize the data people rely on to make
critical business decisions.
With Master Data Services, IT organizations
can centrally manage critical data assets
companywide and across diverse systems,
enable more people to securely manage
master data directly, and ensure the integrity
of information over time.

Master Data Services is a Master Data
Management application that consists of the
following components and tools

Master Data Services Configuration Manager,
Master Data Manager
Master Data Services Web service

Master data hub that provides central
management of master data entities and
hierarchies and collections

Data volumes are exploding with event data
streaming from sources such as RFID,
sensors and web logs
The size and frequency of the data make it
challenging to store for data mining and
analysis.

business decisions in near real-time

SQL Server StreamInsight’s ability to derive
insights from data streams and act in near real
time provides significant business benefits. Some
of the possible scenarios include:

Algorithmic trading and fraud detection for financial
services
