TYPES OF DATA
1. Surveys• Participants enter their own data• Public link or personalized email invitations
2. Database• Longitudinal Data:
• Option 1) Repeating instances where forms can be reused for multiple events (when events are not well defined or subject to change/ad hoc.
• Option 2) Enable module. Defined events offset from a baseline date

OPERATIONS/MODULES
• Data Access Groups• Allow people at multiple sites to contribute to the same database,
without seeing other people’s data.• Calendar & Scheduling
• Create a list of upcoming events and track the status of those events.
• Arms • If multi-armed survey/database, can schedule different events
per arm and different instruments• Randomization
