Overview of the PHENOPSIS DB Information System. Database, Web interface, Web Services, R functions and files (plant images, protocol files, etc) are stored on a Linux server. Environmental data from the growth chambers are automatically inserted into the database, and visible/infrared images are automatically stored and organized on the server. Users interact with the Web interface for offline data, metadata insertion, data consultation and analysis. The connection to the database is either directly performed with SQL requests, or indirectly via R scripts using the RODBC package for data formatting or analysis. Web Services connect to the database for automated data extraction.
