Reengineering of the Bank's IT Infrastructure in Accordance with the Requirements of Business Processes

Graduation qualification work on the topic: «Reengineering of the Bank's IT Infrastructure in Accordance with the Requirements of Business Processes» is a research project in the field of Data Warehouses and its optimization on the example of the Bank. The study is a project that consists of three main parts: the first chapter is a theoretical substantiation of the problem of choosing a data warehouse for large datasets (Big Data), as well as collecting baseline data for the bank for which the research is being carried out, including a description of the organization and its activities. The second chapter is to build a data model in the new Hadoop architecture and implement the transfer of information from the old to the new storage. The third chapter is an assessment and comparison of the source and target solutions for data warehouses. The result of this study is the practical implementation of the new architecture in the contour of the new Hadoop cluster, as well as the evaluation of the implementation results and comparison with the original repository. In addition to practical results, the theory of this study will allow to study aspects of two types of data warehouses - a relational database and Hadoop, to understand their advantages and disadvantages, and also decide on the deployment of a specific architecture based on the final assessment.
