  4. VIEWS / TSS Future Vision Goals and Development Plans • Provide comprehensive comparison and analysis of monitored, modeled, and emissions data with an integrated suite of tools • Enhance and expand decision support applications • Enable providers to upload manage their own data & metadata • Promote an open, extensible, service-oriented architecture • Provide services, components, and tools to air quality developers • Incorporate satellite and meteorological data • Investigate climate change and epidemiological applications and perspectives • Facilitate collaboration and development between organizations

  5. VIEWS / TSS Data Import

  6. VIEWS / TSS Database Architecture • OLTP: • Functions as the “back-end” database • Fully relational and in 3rd normal form • Used for data import, validation, and management • Technologies: Microsoft SQL Server • Data Warehouse Generation System: • Extracts data from the OLTP • De-normalizes and transforms data • Loads data into the Data Warehouse • Builds table indexes • Archives “snapshots” of the database • Technologies: VB, stored procedures • Data Warehouse: • Functions as the “front-end” database • Uses a de-normalized “star schema” • Used for querying and archiving data • Automatically generated from the OLTP • Technologies: Microsoft SQL Server 6
