DPV's data structure

The patients' data are stored in thirteen tables. All of them can be joined using the primary key, the patient's number. Each patient gets a unique number assigned by the program, and the user is not able to influence or change this number. The personal information including date of birth, sex, address, date of first diagnoses, and the type of diabetes mellitus is stored in a table called diabetik  . Each patient has exactly one set of data in this table. The main information about the treatment of his illness is stored in the table verlaufgif  . Each time a patient is in a surgery or hospital a new entry in this table is created. It contains the majority of data including size, weight, blood pressure, quality of the patient's eyes, number of hypoglycemic episodes, insulin therapy, number of injections, and the quality of the patient's self-monitoring. If this treatment was done in a hospital, one additional set of data is stored in the table stat1  . It contains the reason for the patient's presence in the hospital and the time he stayed there. For each day in the hospital, an entry in the table stat3   is produced. It basically contains the amount of insulin given, the calories eaten, and the glucose concentration in the blood. There are further tables for additional examinations and information like extra eye checks, neuronal tests, the psychosocial environment the patient lives in, pregnancy, information about his urine, and special treatments like schooling. For the exact structure of those tables please check the appendix A.
