Device with communication interface and method for controlling database access

A method for controlling database access in a device configured for device-internal processing of data in a text format, the device comprising a communication interface configured for interchanging binary data according to Efficient XML Interchange (EXI) specifications, the method comprising:

• accepting a request for storing a resource in a device-internal database, wherein the request characterizes the resource based on a resource descriptor in a text format;
• extracting an identification number associated with the resource from an EXI string table associated with an encoder, wherein the EXI string table identifies the resource descriptors in the EXI string table with respective identification numbers, wherein a database access control unit of the device is prompted by a read access operation to extract the identification number associated with the resource from the device-internal database and to transfer the identification number to the encoder;
• referencing the resource based on the extracted identification number instead of the respective resource descriptor;
• and
• storing the resource based on the associated identification number, wherein the resource is not stored based on the resource descriptor.

A non-transitory computer-readable storage medium storing instructions executable by a database access controller to control database access in a device configured for device-internal processing of data in a text format, the device comprising a communication interface configured for interchanging binary data according to Efficient XML Interchange (EXI) specifications, wherein the instructions, when executed by the database access controller, are configured to cause the device to:

• accept a request for storing a resource in a device-internal database, wherein the request characterizes the resource based on a resource descriptor in a text format;
• extract an identification number associated with the resource from an EXI string table associated with an encoder, wherein the EXI string table identifies the resource descriptors in the EXI string table with respective identification numbers, wherein the database access controller is prompted by a read access operation to extract the identification number associated with the resource from the device-internal database and to transfer the identification number to the encoder;
• reference the resource based on the extracted identification number instead of the respective resource descriptor;
• and
• store the resource based on the associated identification number, wherein the resource is not stored based on the resource descriptor.
