Impact Analysis

To manage and control Business Intelligence
and Data Warehouse services, planning and change
management we have to track and understand system components
impact and dependencies.

Data Lineage

To manage and understand Business Intelligence
and Data Warehouse services we need
track and understand data lineage and dependencies in long data
transformation chains.

ETL Conversion

Data Warehouse database performance or data loading
migrations bring the need for change in paradigm
and conversion from external tools to database scripts,
ETL to ELT.

Data Lineage

One of the cornerstones of managing Business Intelligence and Data Warehouse ecosystems effectively is the ability to track and understand lineage, impact and dependencies in long data transformation chains. We address this need by combining semantic technologies, grammar based parsing and probabilistic rule-based inference with a powerful metadata repository and efficient aggregation and visualization techniques.

ETL Conversion

A common problem in maintaining data integration and transformation systems in corporate data warehouse environments is the necessity to migrate existing data transformation processes and workflows to new platforms. Often those migrations bring along the need for change in data transformation paradigm and conversion from ETL (Extract-Transform-Load) style to ELT (Extract-Load-Transform) style.

Business Glossary

A rich and powerful metadata repository without a simple and easy interface for business users would not find much use. A well-structured, metamodel driven metadata repository in combination with semantic wiki user interface allows anyone to see and feel complicated metadata structures as familiar wiki pages. This is as close to Knowledge Management as it gets.
