What is needed? Big Data Code Analysis Lack of easy and customizable „manager“ reporting about: – Code quality – Code structure Integration into the Enterprise system landscape

Already available Fast Analysis Multi-dimensional Integration Big Data Widely Used in Controlling and Planning Source: Pendse und Creeth, Managers like Data Warehouses

Use Data Warehouse Technology Abstraction Integration Built for mining Ready-to-use toolsets Established in controlling -> Use what already exists in Enterprises and built on that Tim Frey
