The goal of this thesis is the creation of a web application which helps with widespread hotel maintenance. Individuals who are in charge of rental accommodation, can use this application to find workers, which will then complete day-to-day jobs that are needed for the proper functioning of the accommodation. Workers accept maintenance jobs, such as cleaning the apartment, and the progress is then followed using the application. Users can export earnings or expenses data, and then perform additional data analysis with tools like Microsoft Excel. The web application was created in Spring Boot framework, using Java programming language and the MVC architectural pattern. HTML, CSS and JavaScript were used for the user interface. The data is stored in the PostgreSQL relational database. The graphic elements of the application were made using the Adobe Photoshop graphic design software.
