Data Architect


I began working on the Penguin Sentinels database in August 2006. The Penguin Sentinels database is unique due to its longevity, complexity and scientific significance. With over 120 tables and constant expansion, the relationships between the tables are complicated enough, but the complexities substantially increase once modifications to data collection and entry over a span of more than 30 years are factored in. Recently, we have begun moving our database from dBASE to Microsoft Access and SQL Server. This is a major undertaking which will probably take several years to complete.
