Overview
A data warehouse is a system where data from disparate source systems are structurally integrated, and presented to business users to provide information to answer critical business questions.
Methodology
DSI has developed a proven methodology based on the works of Bill Inmon, Ralph Kimball, and the collective work of our consultants. This methodology has proven to reduce risk and increase return on investment.
Cornerstones of our design methodology:
- Data Integrity
Our solution ensures that data is not missing and referential integrity is maintained. Improved data quality means realized cost savings to your company.
- Restartability
Our solution is architected to restart a failed process without manual steps being undertaken. It should be simple so that it can be executed quickly and easily.
- Repeatability
Reusable templates and processes allow our development cycle to be seamless. This allows us to follow best practice solutions to our projects and lower implementation costs.
