Access to data stored in an embedded database
The solution concerns the access to a number of data files stored in the memory of a data processing device. The device includes a privilege file (P 1 -P 3 ) associated with a user type (ADM, PUBLIC, USER 1, USER 2 ), said privilege file identifying for at least one command (SEL, INS, UPD, SUP) the...

| Zusammenfassung: | The solution concerns the access to a number of data files stored in the memory of a data processing device. The device includes a privilege file (P

-P

) associated with a user type (ADM, PUBLIC, USER
1,
USER
2
), said privilege file identifying for at least one command (SEL, INS, UPD, SUP) the data files on which said command can be executed. A microcontroller is programmed to create, when a user accesses the data files, a set of flags from the privilege file, each flag being associated with a unique data file, the flag indicating whether or not the command can be executed on the associated file. |
