E-R diagram of the embedded database. The database stores Users' profiles, Cases' data and Classifiers' data. The "User" table handles usernames and passwords, as well as administration rights. The "Case" table depends from the "User" table and stores the disease type, case ID and where the information objects are stored. There are three dependent tables, Spectrum, Clinical Record and Tumour type, which store information related to acquisition parameters and MR spectra file formats, clinical information and the list of possible diseases, respectively. Finally, the Classifier table handles which classifier and echo times the system has to choose for display. The Classifier variable table stores × and Y positions of each case in the 2D plot, according to the classifiers selected.
