Formalization of functional and structural characteristics of the mobile To-Do application by UML means

Abstract

This work presents a mobile To-Do application using the tools of the unified UML modeling language. The main goal of the work is to show how UML diagrams can be used to describe in detail the functionality, structure and behavior of a software system even before its creation. The To-Do application was chosen as the object of modeling, as it is a relevant tool for planning tasks and organizing personal time. Key UML diagrams are constructed, including a use case diagram, a class diagram, an activity diagram, and a sequence diagram. Each of the diagrams displays a specific aspect of the application's functionality, user-interface interaction, as well as the internal logic of interconnections between objects. Special attention is paid to the display of CRUD operations and the possibility of integration with calendars. The results of the work confirm the expediency of using UML as an effective tool for modeling information systems in the field of mobile development. The constructed diagrams made it possible to form a clear idea of the system even before the start of programming, which reduced the risks of errors and increased the quality of the final product. The obtained developments can be applied in the educational process, as well as serve as a basis for further research in the field of mobile application design
