Data Acquisition and ETL Architect

Confidential, Springfield

Environment and Tools: PostgreSql, Greenplum, Microsoft Sql Server, SSIS, SQL, PL/SQL, Microsoft Visual Studio, Oracle, Github, XML Spy, IBI ISM, IBI MDC, IBI Data Migrator, C#


  • Taking advantage of Massive Parallel Processing (MPP), this provides a very efficient and robust means of replicating source systems out of production environments and into the EDW, applying a wide variety of cleansing and mastering rules to the data. In the process, this also creates a complete transactional version of each table to allow for dynamically creating dimensional data models on the fly.
  • Designed and implemented a framework of control tables to bring data sources into the enterprise data warehouse. This was coded to make heavy use of parameters in order to maximize code modularity and rapidly deploy the initial load while automatically creating the process to perform nightly incremental loads following an Extract -> Load -> Dedupe -> Replicate -> Propagate structure.
  • The incremental loads could consist of either batch updates or “trickle” loads throughout the day via HL7 messages.
  • Working closely with Information Builders, implemented the OmniPatient BI solution, which includes a “Universal Healthcare Model” to cleanse, master, and merge data from multiple healthcare systems and provide a 360 view of each patient. Data from heterogeneous sources is staged to be absorbed by their interface.
  • After receiving the raw information (XML) for surveys filled out by patients, the ETL process parses and loads this information into a database to get aggregated and reported off of.
