An information management system for association was created, where the association refers to an equestrian club. Task was to create a system that would enable a high-quality overview of the association's content and appointment booking in order to facilitate the management of the association and equestrian sport. The system was created based on a previous detailed analysis of existing solutions. By analyzing these existing solutions, the main task was to see all the advantages and disadvantages of such systems, and to implement as many advantages as possible in the created system, and to "bypass" as many disadvantages as possible. Based on these advantages, the system should enable to view content in an interesting way, using an adequate color scheme, and the possibility of logging in, or registering in the system. This has made it possible for users to book their riding appointment, but also to cancel it. In accordance with it, the system, had an aim which was to create three types of users: unregistered user, logged in user and admin user. Unregistered user has permission to browse webpage about equestrian club, while logged in user has permission to view his own profile, reservations, reservation appointments set by the admin and it has permission to cancel those reservations. As mentioned, admin has permission to add new appointments, view all registered users, view all reservations and the same as ordinary user, admin can view his own profile page. With all of that, the created system fulfilled its main task, which is the reservation of free appointments, but there is still room for additional improvements in the system.
