Dogslife is a web-based epidemiological research project collecting information about the health of Kennel Club registered Labrador Retrievers. It will be used to identify factors which may affect the health and disease of dogs throughout their life.
The project had been running for several years on a bespoke web application which had reached the end of its life. We were asked to migrate it to Drupal 7. The main challenge was the complex logic for the Webform module which delivers the many pages of questionnaire required to collect the data.
