REDCap 

REDCap is a mature, secure web application for building and managing online surveys and databases. Using REDCap’s stream-lined process for rapidly developing projects, you may create and design projects using 1) the online method from your web browser using the Online Designer; and/or 2) the offline method by constructing a ‘data dictionary’ template file in Microsoft Excel, which can be later uploaded into REDCap. Both surveys and databases (or a mixture of the two) can be built using these methods.
