Planning a wedding can be both thrilling and challenging, particularly when it comes to finding and booking the ideal venue. In Kigali, Rwanda, couples face difficulties due to the absence of a comprehensive online resource for wedding venues. This lack of centralized information complicates the comparison of options based on factors such as location, size, aesthetics, and cost, while the traditional booking process is often marred by cumbersome phone calls, in-person visits, and complicated paperwork. To alleviate these issues, this project introduces the Online Booking Wedding Venue Management System, designed to streamline the venue selection and booking process for couples in Kigali. The system provides a centralized database of available wedding venues, accessible through a userfriendly web interface. Built using HTML, CSS, Node.js, Express, and MongoDB, the platform simplifies the search for and reservation of wedding venues, thereby reducing stress and saving time for users. The project aims to address the challenges faced by couples by offering a seamless and efficient booking experience. The system’s core features include real-time availability tracking, detailed venue descriptions, and an intuitive booking process. By improving accessibility to venue information and facilitating a more straightforward booking procedure, the platform provides significant benefits to couples, venue managers, and related stakeholders. In summary, the Online Booking Wedding Venue Management System addresses key issues in the wedding planning process in Kigali by offering an innovative, user-centric solution. The system enhances convenience, reduces administrative burdens, and improves overall user satisfaction. Future enhancements could include mobile application development and advanced features to further refine user experience and operational efficiency.
