3. SQL Server 2005 The comprehensive, integrated data platform
SQL Server is a comprehensive, integrated end to end data platform including:
Core database engine: secure, reliable, highly available data store
Data transformation and replication services (DTS, Replication) facilitate enterprise wide data integration, data warehouse creation, data replication for distributed or mobile data processing applications, and systems availability
Deriving additional value from your data: Notification Services, Data Analysis, Data Mining, Reporting
Management tools – SQL specific management suite as well as tight integration with tools such as MOM, SMS
Development tools – BI specific development toolset as well as tight integration with Visual Studio
Flexible, extensible: Every major subsystem in SQL Server ships with it’s own Object Model and set of APIs to you to extend the data system in any direction that is unique to your business
Interoperable: Standard data access protocols drastically reduce the time it takes to integrate data in SQL Server with existing systems. In addition, native web service support is built into SQL Server to ensure interoperability with other applications and platforms
SQL Server is the only database to include all of this functionality out of the box. Competitive offerings rely on third part applications to address key functionality and/or charge for incremental functionality (such as BI)
Also provide entry level SKUs for lightweight data needs (Express, Workgroup)
Scales to your needs: support for databases from the mobile device to the datacenter
SQL Server Mobile, 32 bit, 64 bit
Hardware platform range of SQL Server includes:
Single Pocket PC CPU systems,
Throughout mobile and desktop class PCs,
Through Multi-CPU server systems
All the way up to 64-processor Enterprise Data Center systems

6. Proactive Caching No more “cube processing”! Combines
OLAP class query performance
Real Time data access
Easier said than done…

7. Proactive Caching Challenges
Efficiency
How do we not drive the system insane with frequent updates
How fast can the caches catch up
Performance:
How to balance between Latency and Performance
“no free lunch” but you can order ala cart
Notifications:
How does Analysis Services know that something changed in the RDBMS

8. Achieving Consistent Performance
Users are very annoyed when a system behaves inconsistently
A consistently slow system is often more usable than a a fast system with occasional slowness.
The classic HOLAP pitfall
Consider Automatic MOLAP to ensure consistent performance
Automatic MOLAP

9. Continuously Updated Source Systems
OLTP systems and trickle-feed DW will always get updated
Problem: No time for cache to ever catch up
A lot of false starts or Silence Interval never observed
Solutions
Give up – use Real Time ROLAP
Use automatic MOLAP with Silence Override
Use auto scheduled MOLAP

10. Getting Change Notification from the Data Source
Problem – how do we know that the data has changed?
Solutions:
Use event trace entries
Let the application notify us through a Web Service call
Poll the data source using SQL queries

11. Real Time OLAP It can be done – but with caution
Should only be done if the need is REAL TIME
In most cases near real time is sufficient
Business value is less time from action to analysis
