Data Storage in CommCare
CommCare collects and stores data primarily in three ways:
...
Form Submissions
When a user fills out a form on a mobile or web app, the data is encrypted and transmitted securely to CommCareHQ.
Each form submission is stored in a structured format with a unique identifier and timestamp.
Data is backed up and maintained to prevent data loss.
...
Case Management
Cases allow users to track entities (e.g., patients, households, projects) over time.
Each case has a unique case ID and is linked to related form submissions.
Data is automatically updated and version-controlled.
...
Multimedia Storage
Images, audio, and video files collected in forms are stored in cloud-based repositories.
Files are compressed and encrypted to optimize storage and maintain security.
Access to multimedia data is restricted based on user roles and permissions.
...
CommCare Servers and Infrastructure
CommCare operates on secure, scalable cloud infrastructure.
...
Cloud Hosting & Storage
CommCare data is primarily hosted on AWS (Amazon Web Services), ensuring high availability and scalability.
Servers are distributed globally to ensure low-latency access for users in different regions.
...
Data Security & Encryption
In Transit: All data is transmitted over SSL/TLS encryption to protect it from interception.
At Rest: Stored data is encrypted using industry-standard AES-256 encryption to prevent unauthorized access.
...
Backup & Redundancy
Data is automatically backed up to prevent loss in case of server failures.
Redundant storage systems ensure high data availability and disaster recovery.
...
Compliance & Regulatory Standards
CommCare complies with GDPR, HIPAA, and other data protection regulations.
Role-based access control (RBAC) ensures only authorized users can view or modify data.
...
Offline Data Storage & Syncing
Mobile devices store a local copy of necessary data for offline use.
