Abstract: Systems and methods for collecting, managing and sharing date include a server computer system that receives a data set containing flat data from a client computer system. The server computer system generates a relational database from the flat data and provides, through a web-based interface, user options for modifying the relational database, as well as application programming interfaces configured to provide data of the relational database to third parties. In accordance with another implementation of the invention, a client computer system sends flat data to a server computer system, causing the server computer system to generate a relational database from flat data. The client computer system receives and displays a web-based user interface that identifies fields of the flat data as part of the relational database, along with user options for modifying the fields of the relational database.
