SDE is another proprietary development, a complete system that allows clients to record data gathered on paper.
The system is comprised of 3 independent modules:

Design Module With this module, the questionnaire is designed, reproducing the printed questionnaire. The variables are entered, in addition to possible value ranges and associated skips.

Record Module This module records all gathered questionnaires, while checking for inconsistencies. The data entry can be done in one or several PCs simultaneously.

Administration Module With this module, duplications are controlled, and data from all questionnaires are exported to a single file that is compatible with standard statistical analysis programs.
