The Mission System Directory (MSD) is a web application built using Flask and React.js that allows the seamless reference to and management of information systems. MSD allows users to quickly discern the references, requirements, responsible personnel, and other necessary information from any given information system. Admin on the site can create and edit existing data to ensure that the displayed information is accurate and up to date, replacing an existing methodology that is slow, costly, and outdated. MSD is always growing and plans to include cost management data and business requirements, among many other items. MSD incorporates open-source software and is in the process of contributing open-source libraries to the javascript and python communities.
