This document describes an online ad agency management system. The system was developed using ASP.Net on the front end and SQL Server on the back end. It allows administrators to manage users, advertisements, and channel timings. Users can view slides, animations and videos. The system aims to provide advertisement cost details for various channels based on the client's budget. Methodologies used include gathering requirements, designing ER diagrams, use case diagrams, and other system design diagrams. Future enhancements could include additional functionality as needs arise.
