Limiting access to columns

Major changes in version 4.99 of the Research Operation Utility application result from the CADAS Platform's adaptation to requirements of the EU General Data Protection Regulation, commonly known as the GDPR. Thanks to the these changes it is now possible to define user groups authorized to view and to modify protected data stored in databases: users, respondents or results. This allows to limit the group of users having access to personal data and to increase the security of stored data.

A category of users who can access protected data and a category with limited data access can be defined in the system. For users with limited access, confidential data is displayed in a scrambled form to prevent identification of respondents.
