Servlets and Applets make it very functional to integrate in library management systems to enhance the modernization of library functionalities. Servlets are Java programs that are located in the server side of the network that helps in handling clients’ requests and responses while applets are Java programs that are located at the client side of the network that helps in improving the interfaces. These with an SQL database can be used effectively to store data by updating the data in real-time saving time on a lot of processes. These are some of the concerns that have been addressed in this report through a design and implementation of a library management system that involves use of servlets, and applets with an SQL database. Therefore, the major goal entails designing a system that addresses book catalog, client accounts, and borrowing systems. It believes that it is very important because it helps to make library functioning better by minimizing the role of people's mistakes and offering good navigation through the libraries’ resources for both libraries’ staff and readers.
