Tracking Network EA Model
Focus of Tracking Network EA n n Technology Standardization and Reuse Interoperability Data Sharing Overall Program Efficiency and Effectiveness
Technology Standardization and Reuse n Standards based approach that promotes and facilitates Technology Standardization and Reuse with a philosophy of first Reuse, then Buy, then Build. u Technology Standardization • • • u Standard Health Information Contract Language (Included in Current Tracking Network Contracts) American Health Information Communities (AHIC) Use Cases Health Information Technology Standards Panel (HITSP) Interoperability Specifications Reuse • • • Reuse of GIS capabilities (NCEH GRASP) Selected COTS product - Business Objects Web Intelligence Built Row Level Security to fit specific business need
Interoperability n Consistent methodology and technology for interoperating within CDC and with State Grantees and Federal partners. u PHIN MS for data transfer u Secure Data Network (SDN) for authentication u XML for importing and exporting metadata u XML Schemas for defining the contract for data feeds from partners to CDC (Will go from CDC to partners in the near future)
Data Sharing n Evolution, adoption and exposure of data and vocabulary standards that provide semantic consistency for the Tracking Program. u Use of FIPS Codes and ICD-9 Codes where possible u PHIN VADS Vocabulary Web Services into a future version of the Metadata Creation Tool u EPA’s Exchange Network for receiving data from one of our Federal Partners, the EPA u Use of XML for importing and exporting metadata u Use of XML Schemas for defining the contract for data feeds from partners to CDC (Will go from CDC to partners in the near future)
Overall Program Efficiency and Effectiveness n Leverage work that has already been done, simplify systems development and take advantage of economies of scale. u Use of PHIN MS for data transfer u Used FGDC template to derive Metadata Template u Proven JAVA frameworks (i. e. Spring, Hibernate and Strut) used for development in a timely fashion while promoting best practices
