This document outlines the design of an internal mailing system. It includes: - An introduction describing the purpose and modules of the system. - System design sections covering use case diagrams, data flow diagrams, and database/class diagrams. - A data dictionary defining the tables used to store user, admin, mail, and other data. - Interface screenshots of the home and login pages. - References used in designing the system. The overall goal is to develop a web-based mail client that allows users to send, receive, organize and delete mail through an authentication process and interface. System design and data storage are described in detail through various diagrams and a data dictionary.
