In the theoretical part of the thesis, the student analyzes the pitfalls of working with a large and complexly related dataset of web applications in general and in the context of JPA, with a focus on both the performance and the implications on the development process. The practical part focuses on how were these issues addressed in the UAS framework, what were the limitations of this solution and how were these limitations reflected in the development process and the quality of the final product. Afterward, the student elaborates on what are the alternatives, carefully analyzing each option from multiple points of view and consulting them with the involved parties, until a consensus is reached. Eventually, the solution deemed as the best is implemented into the new UAS2 framework. The thesis is created in cooperation with the industrial partner InQool a.s.
