3. SQL Database Scalability Considerations –Database Search Indexes written & applied to several data sets –Outcome: performance trade off –The positive: Substantially increased data retrieval time Data download time for registered sets of Daily and Hourly values now range between quick to nearly instantaneous!! –The negative: Substantially slower data entry. Nearly an hour to load a one hour set of values. Not a sustainable process.

4. SQL Database Scalability Considerations –Solution: Recent Values vs. Archive 2 separate sets Small dynamic set containing recent values (no indexes needed). This will receive current updates. Large static set with full 15/17 yr history of archive values. –Additional Solution: New platform at Arlington Regional Data Center (ARDC) Fail-over power back up 24/7 sys-op support Enterprise class data server

6. Update stream via Unidata Local Data Manager (LDM) LDM Connection became active and remained active November 22 nd. –Routed from WGRFC through NWS Southern Region Headquarters and then to UTA. –Extremely dedicated effort by Mike Thompson of NWS to coordinate the configuration for LDM.
