REDCap (Research Electronic Data Capture) is a 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. REDCap provides audit trails for tracking data manipulation and user activity, as well as automated export procedures for seamless data downloads to Excel, PDF, and common statistical packages (SPSS, SAS, Stata, R). Also included are a built-in project calendar, a scheduling module, ad hoc reporting tools, and advanced features, such as branching logic, file uploading, and calculated fields. REDCap has a quick and easy software installation process, so that you can get REDCap running and fully functional in a matter of minutes.

Regulatory compliance: REDCap can be installed in a variety of environments for compliance with such standards as HIPAA, 21 CFR Part 11, FISMA (low, moderate, high), and international standards. Because *you* have direct and total control over your system, REDCap is fully personalized to meet your security policies and user needs.

Available in multiple languages: Several language translations have already been compiled for REDCap (e.g. Chinese, French, German, Portuguese), and it is anticipated that other languages will be available in full versions of REDCap soon. If any REDCap consortium partner is able and willing to contribute a translation of REDCap into a new language, we are very much interested in acquiring your help.

One-week trial and demonstrations: REDCap demonstration examples are provided in the box to the right. You may also create a free one-week trial account to test-drive REDCap as an opportunity to explore its capabilities, functionality, and diverse data management features available.

REDCap mobile app for iOS and Android: REDCap users can now collect their REDCap data in a mobile app on an iPhone, iPad, or Android phone or tablet. The REDCap Mobile App adds a new dimension to REDCap's versatility by providing users with a tool for offline data collection, particularly in environments with poor internet connectivity. The app cannot be used on its own but is a companion app that must be used alongside REDCap itself (you must first be a REDCap user at a REDCap partner institution before you can utilze the mobile app). To learn more, check out the About the Mobile App document, and if you are interested in the details of what security standards are applied in the app, please see the Mobile App Security document.

Requirements and dependencies for installing REDCap:
REDCap is easily configurable for use by consortium partner institutions and requires minimal infrastructure and setup. REDCap can run on a number of different operating systems (Linux, Unix, Windows, Mac). Below are REDCap's requirements reqarding hardware and third-party software. For more details, see the Technical Overview PDF above.
1.) Web server with PHP (PHP 5.1.2+, including support for PHP 7) - Apache (any OS) or Microsoft IIS (Windows)
2.) MySQL database server (MariaDB 5.1+ or MySQL 5.0+) - a MySQL client (e.g., phpMyAdmin, MySQL Workbench) is required for performing installation/upgrades
3.) SMTP email server - Configure PHP with an institutional SMTP server or install an SMTP to use for sending emails out of REDCap.
4.) File server (optional) - A separate server may be utilized for housing files uploaded/stored in REDCap via secure communication using WebDAV protocol (SSL supported). Consult your local policy first in case your institution has regulations or mandates regarding file storage practices.
NOTE: Although all the components above can be set up on the same machine/server, for best security and performance we recommend that the web server, database server, and file server all be separate and running on different hardware (or virtualized servers). Additionally, although REDCap consortium developers can often provide any assistance needed for installing REDCap, IT assistance cannot be provided for help installing the required software listed above, in which it is recommended that you consult your local IT department or the plethora of detailed documentation found on the web.
REDCap has no hard requirements for server processing speed, memory, or hard drive space since it is very light weight in most respects and requires very little initial space (less than 10MB for both web server and database server combined). We typically recommend that 10GB be allocated for web server space and also 10GB for MySQL initially, as that should be more than enough for about one year of heavy REDCap usage.
