Why Data Models? Complex, common component of all projectsComplex, common component of all projects Significant time is spent on data modeling for each implementationSignificant time is spent on data modeling for each implementation Data migration is the longest and most expensive part of any projectData migration is the longest and most expensive part of any project Adoption of common models can reduce implementation timeframes, cost, and riskAdoption of common models can reduce implementation timeframes, cost, and risk Key to future data sharingKey to future data sharing
