David Colbourn
Sr Data Architecture/ Modeling RDBMS and Big Data
SUMMARY:
I am skilled in Data Modeling, DBMS, PM and specialize in development efforts that standardize workflows, data warehouse federation and virtualization. Data models with enterprise level conformed dimensions and taxonomy and grain specifications are only part of my capabilities. I can help you id and integrate unstructured and semi structured data lakes with structured RDBMS systems and BI reporting or data linage, master data management and meta data management. I
act as or provide support for designer, administrator and some coding all in support of a data owner, SME or steward. I also have a data management strategy for mixing unstructured data with semi and fully structured data. Beyond that I can support the generation of specifications for near real time ODS, departmental governance and business rules needed for an ESB.
I am a published author and have an article in Information Management on how to devise a data strategy. I am versed in Cassendra DB and Agile development. Data Base Management Systems Utility DDL and DML supported include; Oracle, DB2/UDB, SAS and SQL Server. Data modeling support includes; Star for OLAP and Snow flake third normal form for OLTP for both dimensional modeling and Data Mart design with ETL support while using All Fusion, Sybase SAP Power Designer, IBM Rational System Architect and Sparx Enterprise Architect systems. In the past as an infrastructure engineer, I have set up and run an R&D Lab to facilitate on site benchmarking of various configurations. I install and administer new software and test the interfaces
to existing system including firewalls and SAN network storage. I have integrated many COTS packages. My carrier path includes; mainframe development, systems programming, capacity planning, data base design, System Architect administration and BI architect positions. BI access to unstructured data with DW access into ESB/SOA and MDM systems design using ERD BPM and BMM models is needed for policy feedback.
Experience
Data Architecture/ Modeling Support
A Leading Credit Union in Silicon Valley via Kelly Software
September 2017 - Present
I am doing data modeling manager work for the data analytics group. The company is the lead credit union for IT workers. I designed and implemented a conformed dimensional enterprise data warehouse using a Kimball Zachman approach. The environment was an Erwin OLAP setting for relationally linked indexed tables in MS SQL Server. This work included the development and enhancement of procedures for managing table and attribute definitions as well as data linage and a proposed MDM data security interface. I design ODS, Data Warehouse and data lakes for RDBMS and Big data systems. Support for a data warehouse by departmental feed the views with source to target mappings for ETL specification, access path analysis and performance tuning and maintenance with other root cause analysis were also accomplished. Identification of PII data for SME governance analysis and design and generation of data structures to support ETL automation was also included. The modification of the work flow between the business analysts, data modelers and ETL dev-ops group was performed and accompanied by naming standard punch ups and industry best practice implementation.
