Abstract

In various embodiments, RFID events are pre-processes with filtering logic by a mobile interrogator/reader before being inserted into tables of a local relational database on the mobile device when the mobile device cannot otherwise communicate collected events to a centralized data hub. The RFID events are stored in a normalized format that provides a simple, efficient, and standard interface for persisting the RFID events such that local access from applications on the mobile device is provided.

Claims

1. A method for accessing data, the method comprising:

generating an RFID event at a mobile device;

determining whether to store the RFID event on the mobile device;

determining whether to synchronize RFID events stored on the mobile device with a server; and

updating an online database on the server with the RFID event.

2. The method of claim 1 further comprising:

storing the RFID event in a offline database on the mobile device.

3. The method of claim 1 further comprising:

accessing the RFID event using an application on the mobile device when the mobile device is offline.

4. The method of claim 1 wherein determining whether to store the RFID event on the mobile device comprises determine whether a link exists between the mobile device and the server.

5. The method of claim 1 wherein determining whether to synchronize RFID events stored on the mobile device with a server comprises detecting a link between the mobile device and the server.

6. The method of claim 1 wherein updating the database on the server with the RFID event comprises synchronizing an offline database on the mobile device with the online database on the server.

7. The method of claim 1 further comprising:

updating an offline database on the mobile device with metadata associated with one or more applications on the mobile device.

8. A computer readable medium configured to store a set of code modules which when executed by a processor become operational with the processor for accessing data, the computer readable medium comprising:

code for generating an RFID event at a mobile device;

code for determining whether to store the RFID event on the mobile device;

code for determining whether to synchronize RFID events stored on the mobile device with a server; and

code for updating an online database on the server with the RFID event.

9. The computer readable medium of claim 8 further comprising:

code for storing the RFID event in a offline database on the mobile device.

10. The computer readable medium of claim 8 further comprising:

code for accessing the RFID event using an application on the mobile device when the mobile device is offline.

11. The computer readable medium of claim 8 wherein the code for determining whether to store the RFID event on the mobile device comprises code for determine whether a link exists between the mobile device and the server.

12. The computer readable medium of claim 8 wherein the code for determining whether to synchronize RFID events stored on the mobile device with a server comprises code for detecting a link between the mobile device and the server.

13. The computer readable medium of claim 8 wherein the code for updating the database on the server with the RFID event comprises code for synchronizing an offline database on the mobile device with the online database on the server.

14. The computer readable medium of claim 8 further comprising:

code for updating an offline database on the mobile device with metadata associated with one or more applications on the mobile device

15. A system for accessing data, the system comprising:

a mobile device configured to generate an RFID event, to determine whether to store the RFID event in a local relational database one the mobile device, and to determine whether to synchronize RFID events stored on the mobile device with a centralized relational database; and

a server configured to update the centralized relational database on the server with the RFID event.

16. The system of claim 15 further comprising:

one or more applications configured to access the RFID event on the mobile device when the mobile device is offline.

17. The system of claim 15 wherein the mobile device is configured to determine whether a link exists between the mobile device and the server to determine whether to store the RFID event on the mobile device.

18. The system of claim 15 wherein the mobile device is configured to detecting a link between the mobile device and the server to determine whether to synchronize RFID events stored on the mobile device with a server.

19. The system of claim 15 wherein updating the database on the server with the RFID event comprises synchronizing an offline database on the mobile device with the online database on the server.

20. The system of claim 15 wherein the server is configure to update the local relational database on the mobile device with metadata associated with one or more applications on the mobile device.

21. A computer readable medium configured to store a set of code modules which when executed by a processor become operational with the processor for providing persistence to RFID events, the computer readable medium comprising:

code for storing RFID events generated by a wireless RFID reader in a local relational database on the wireless RFID reader;

code for determining whether one or more conditions are present that enable to the wireless RFID reader to wirelessly exchange data with a centralized relational database;

code for determining, based on whether the one or more conditions are present, whether one or more applications on the wireless RFID reader access RFID events stored using the local relational database or stored using the centralized relational database;

code for transferring RFID events as stored in the local relational database to the centralized relational database.
