Design and Implementation of an application Data Lake to support Repair Process in Baker Hughes

Digital Revolution leads companies to invest and focus their attention on leveraging the potential of digital technologies. Baker Hughes Company, in Energy Technology industry, is driving its digital transformation investing in new technologies or improving the existing ones. The objective of this thesis project is the study and the development of an application Data Lake to support the Repair Service Team of Baker Hughes. Repair Process is fully tracked on an internal web application, called Repair One Portal (ROP) and all its data are stored in a relational database. Data Lake is an emerging alternative system to the Data warehouse. It answers the need of extracting information from different kinds of data in a flexible and not expensive way. It decouples operational database from the repository for the analysis, maintaining a raw data copy on the Data Lake instance. The implemented Data Lake provides a report layer for Repair data, a starting point for data integration with other data sources, improves logics and information accessibility, allowing the monitoring of an important area of the company. The thesis aims to describe the case study, the choices that drove the solution design phase, the challenges faced during the implementation, with the ambition of providing a solution model for similar initiatives.
