The aim of the project is to migrate a Cognos data warehouse to Microsoft SQL Server. The ETL routes were implemented using stored procedures in T-SQL or SSIS packages were created. The data cubes were implemented using SSAS and the reports implemented using SSRS. In 2012, the entire data warehouse was converted or migrated from Cognos to Microsoft SQL Server. The task was to support and train the database developers at Liebherr accordingly so that they could successfully implement this migration. In special cases, corresponding development work for more complex tasks that could not be solved by the teams took place.

• Requirement engineering and creation of the concept.
• Advice and training for internal employees on converting a Cognos DWH to a Microsoft SQL Server DWH.
• Creation of the ETL processes (SSIS and T-SQL).
• Creating the cubes (SSAS).
• Creation of reports and ad hoc evaluations (SSRS).
