Data Preservation – Converted unmanaged T-Sql code into SSIS package that implemented transformation of vital records data from raw input to cleansed data to data linked to conformed dimensions and finally to updated representation of production facts and dimensions. Data representation of slowly changing dimensions allowed user to trace and review provenance of data through entire process.

Data representation of slowly changing dimensions allowed user to trace and review provenance of data through entire process. Metadata designed and implemented to represent business and data transformation rules to include cleansing, geographical validations, as well as weighted matching logic to production database facts and dimensions. Stop gap MS Access database augmented to allow for viewing and approval pending completion of web interface. Landing, cleansing, matching, and merging implemented as single turn key application.Vital Records Data Warehouse – Initiated conversion of un normalized birth records into preliminary facts and dimensions. This was designed and implemented as an SSIS package that split single table with large number of columns into a single fact table and multiple logically defined dimensions.(SQl Server, T-SQL, MS Management Studio, SSIS, MS Visual Studio, C#, MS Access, VBA) Show less

Allowed for tuning customized to requirements of ad hoc analysis. Type two slowly changing dimensions universally applied using auxiliary columns applied to destination table definitions. Driven by meta data representations of tables, primary key definitions and foreign key relationships between tables interacting with data dictionaries of source and destination data bases. Allows for addition of tables without programmatic changes. Includes a logging system which allows for the detection and correction of execution failures at the table level as well are automated resubmission of failed steps. QA process highlights differences between the adhoc analysis environment and the clinical data repository. Cerner Millenium, vocabularies/ontologies to include CPT, ICD-10, NDC, LOINC,…Study Snapshot- A snapshot of the Ad Hoc analysis environment is extracted for a given study at a point in time. Comma separated value (csv) extracts are generated in a human readable, more de normalized format (vs. integer references). CSV extracts optionally exported into a user friendly MS Access format with relationships between tables enforced, and data dictionary definitions applied. Phase 2-Augmented the ad hoc analysis environment to initiate and allow for ongoing database tuning, and enabled future in-situ processing of studies. (Would limit the need for maintaining separate copies of data per study through references to ad hoc analysis environment). Allowed for flagging and tagging approach for detection of repeating sets as well as for detection of patterns of usage of medical vocabularies and ontologies (SNOMED, ICD10 diagnosis and procedures, CPT …).(Oracle 11g, SQL Developer, PL/SQL, scripts and packages, MS Access, VBA (Excel and Access) Show less
