7. How Can SQL Server Help? Document Management Document Management Enterprise Resource Planning (ERP) Enterprise Resource Planning (ERP) Manufacturing Resource Planning (MRP) Manufacturing Resource Planning (MRP) Race car setup data management Race car setup data management Race car data systems management Race car data systems management Simulation data management Simulation data management Workflow management Workflow management

8. Document Management Practice/Race Reports Practice/Race Reports Car design/CAD management Car design/CAD management Technical Bulletins Technical Bulletins Timing and Scoring Reports Timing and Scoring Reports Best practices Best practices

9. Race Car Data Systems Most teams use Pi Data Systems for sensor data collection Most teams use Pi Data Systems for sensor data collection Typical setup involves 30+ sensors Typical setup involves 30+ sensors A practice outing produces about 10-15MB of data A practice outing produces about 10-15MB of data Data must be disseminated to track and shop personnel as quickly as possible Data must be disseminated to track and shop personnel as quickly as possible

10. Race Car Setup Tire data Tire data Shock data Shock data Vehicle setup information Vehicle setup information Sensor Data Sensor Data Practice vehicle outing/run data Practice vehicle outing/run data Race log Race log Driver feedback Driver feedback

11. Simulation Data Rig data results Rig data results Computer simulation results Computer simulation results Must be fed with real data Must be fed with real data Results must be fed back to central database Results must be fed back to central database

12. SQL Server to the Rescue! All data is stored in SQL Server All data is stored in SQL Server Security Security Provides an easy way to back up all critical data Provides an easy way to back up all critical data Provides replication services to maintain a high level of data availability Provides replication services to maintain a high level of data availability

13. SQL Server Replication Snapshot replication Snapshot replication Provides initial set of data for merge replication Provides initial set of data for merge replication Good for infrequently changing data Good for infrequently changing data Merge replication Merge replication Good for server to client applications Good for server to client applications Transactional replication Transactional replication Ideally suited for server to server Ideally suited for server to server

14. Merge Replication Snapshot replication used to populate initial data Snapshot replication used to populate initial data Can be based on a push or pull system Can be based on a push or pull system Can create multiple publications from the same database Can create multiple publications from the same database Based on a Publisher/Subscriber system Based on a Publisher/Subscriber system Can deal with schema changes Can deal with schema changes

15. Merge Replication Types (Push) Publisher (Server) connects to the Subscriber (client) Publisher (Server) connects to the Subscriber (client) Works with SQL Server Express Works with SQL Server Express Can bog down server if there are a lot of clients (each client is synchronized via a SQL Server Agent job) Can bog down server if there are a lot of clients (each client is synchronized via a SQL Server Agent job)

16. Merge Replication Types (Pull) Subscriber (client) initiates connection to Publisher (client) Subscriber (client) initiates connection to Publisher (client) Not available with SQL Express (No SQL Server Agent) Not available with SQL Express (No SQL Server Agent) Can use anonymous subscriptions and write your own synchronization agent Can use anonymous subscriptions and write your own synchronization agent

17. Merge Replication Limits 256 Articles 256 Articles Limits the number of stored procedures Limits the number of stored procedures Creating multiple publications can be hazardous! Creating multiple publications can be hazardous! 246 Columns in a table 246 Columns in a table Think vertical table design Think vertical table design 1024 Bytes for a column used in a row filter 1024 Bytes for a column used in a row filter

18. Central Race Team Scenario SQL Server cluster at the main facility SQL Server cluster at the main facility Local non-travelling clients connect directly to cluster Local non-travelling clients connect directly to cluster Travelling clients run SQL Express and connect periodically Travelling clients run SQL Express and connect periodically Information is available and updated throughout the race Information is available and updated throughout the race Allows everyone to be a “backseat” crew chief Allows everyone to be a “backseat” crew chief

19. The Hauler Scenario This is where the race team lives on the weekends This is where the race team lives on the weekends Local Server SQL that can act as publisher and subscriber Local Server SQL that can act as publisher and subscriber Local SQL provides faster replication times for local clients Local SQL provides faster replication times for local clients Allows replication within a team even if connection to shop goes down Allows replication within a team even if connection to shop goes down

20. SQL Server Compact Can participate in replication Can participate in replication Great for small devices used for data entry Great for small devices used for data entry Tire data Tire data Trackside weather information Trackside weather information GPS enabled devices GPS enabled devices

21. In Conclusion SQL Server in racing is exciting!!!! SQL Server in racing is exciting!!!! New SQL Server Filestream data type will make working with large data types easier New SQL Server Filestream data type will make working with large data types easier Technology and data sharing really do help win races Technology and data sharing really do help win races THANK YOU!
