The Challenge

OTTO faced operational inefficiencies due to fragmented business logic across multiple BI tools and a heavy dependence on IT specialists for data access and reporting. This setup made it difficult to maintain consistent data definitions and business logic across platforms.

The Solution

OTTO developed the Exasol Semantic Layer to centralize and streamline data access. They built a Python-based query engine and a dynamic virtual table layer using Exasol’s Virtual Schema technology, which provided a consistent, single source of truth for data across the organization.
