In the context of the course Data warehouse and decision support (NF26) taught at Université de Technologie de Compiègne (UTC), I have implemented a Data Warehouse (DW) containing relevant data of a fictitious company (called Fantastic) selling books. The DW goal was to identify the factors that affect the sales of the company. Two software solutions have been implemented. The solution in the repository is the first one: implementation of an ETL ex nihilo, in batch mode and without handling the incremental aspect of the data structure. Implementation and use of the DW in Oracle Database.

Technologies: UML, SQL and PL/SQL
