REDCap: Research Electronic Data Capture
REDCap is a secure, web-based application for securely building and managing online surveys and databases. REDCap’s easy design environment allows you to quickly create web-based databases and data capture forms with special features like ad-hoc reporting and scheduling.
Using REDCap's streamlined process for developing projects, you may create surveys, databases, or a combination of both using
1) the online method from your web browser using the Online Designer or
2) the offline method by constructing a 'data dictionary' template file in Microsoft Excel, which can be later uploaded into REDCap.
