Use case diagram for the biobanking activity at Gaslini Hospital. We have identified four actors in the Biobank Management system. The biologist banks tissue and blood samples, extracts RNA and DNA from them and performs structural and expression genomic analyses. The clinician periodically provides clinical data about patients. The bioinformatician retrieves the collected information and processes it using classifiers and machine learning tools. The administrator manages users, groups and functions; creates and activates functions and data types for specific groups. In a small lab or group another actor (e.g. biologist) may also have administrative role.
