Accessing data tag information using database queries

A system for mapping data between a data tag and a database application, comprising:

• a mapping device comprising:
• a mapping interface for reading a mapping definition;
• a wireless interface for communicating with the data tag using a data tag query protocol;
• and
• a database interface for communicating with the database application using a database query protocol;
• wherein the mapping device is configured to implement communication between the wireless interface and the database interface by mapping between the data tag cuery protocol and the database ciuerv protocol using the mapping definition;
• and
• a storage device that is separate from the mapping device, the storage device for storing the mapping definition separately from the mapping interface.

A computer program product readable by a computer and embodying a program of instructions capable of mapping data between a data tag and a database application using a mapping interface, the program comprising instructions operable to cause the computer to perform:

• communicating with the data tag via a wireless interface using a data tag query protocol;
• communicating with the database application via a database interface using a database query protocol;
• reading a mapping definition;
• and
• exchanging data between the wireless interface and the database interface by mapping between the data tag query protocol and the database query protocol using the mapping definition, the mapping being performed in the mapping interface;
• wherein the mapping definition is stored separately from the mapping interface.
