This post is about building a unified OLAP platform. An insurance company tries to build a data warehouse that can undertake all its customer-facing, analyst-facing, and management-facing data analysis workloads. The main tasks include: 

Self-service insurance contract query: This is for insurance customers to check their contract details by their contract ID. It should also support filters such as coverage period, insurance types, and claim amount.

Dashboarding: This is to create a visual overview of the insurance sales trends and the horizontal and vertical comparison of different metrics.
