I can offer a lot of experience in the use of data and databases for decisionmaking. For me the challenge is to make the best and most effective use of data for all kinds of decisionmaking (policy, strategic, operational).
datawarehouses, ETL, and business intelligence on large databases (up to 200 mln records)
statistics, monitoring and analysis of neighbourhoods (especially poorer ones)
statistics, monitoring and analyses of youth delinquency (especially ethnic backgrounds and chances for recidivism)
statistics and monitoring of dutch primary education (especialy school results and black and white schools)
