Abstract

A system, method, and computer program product for building JSON message relationships for offline operation of an enterprise application is presented. The claimed embodiments address the problem of mobile application behavior during periods of limited access to backend application services and data. More specifically, some embodiments are directed to approaches for capturing request and response information communicated between a client device and application server when connected by a network, and storing respective relationships using the captured information. The stored requests and responses and respective relationships are used to emulate the backend services provided by the application server when the client device is disconnected from the network. In one or more embodiments, a crawler on the client device can generate simulated online requests to build a set of information for use by the emulator when the client device is disconnected from the application server.

Claims

1. A method for offline operation of a client application on a client device using a client-local database of online activity records, the method comprising:

receiving, from a networked component, computer code comprising at least a portion of an emulator processing entity to execute on the client device, the emulator processing entity being configured to allocate memory on the client device to store at least one online request and least one online response into a client-local database;

sending one or more online requests from the client application to the networked component;

receiving one or more online responses from the networked component, the online responses to the client application being responsive to at least one of the one or more online requests;

storing, into the client-local database of online activity records, at least one relationship between the one or more online requests and respective one or more online responses; and

using the emulator processing entity to retrieve stored instances of the respective one or more online responses from the client-local database to allow the client to operate in an offline mode when disconnected from the networked component.

2. The method of claim 1, wherein the emulator processing entity is configured to process one or more occurrences of subsequent requests to produce offline responses when the client device is disconnected from a network.

3. The method of claim 2, wherein the emulator processing entity serves to retrieve stored instances of the one or more online responses based at least in part on a one-to-one relationship with the subsequent request.

4. The method of claim 2, wherein the emulator processing entity is configured to deliver one or more offline responses to the client application when the client device is disconnected from an application server.

5. The method of claim 1, wherein one or more online requests and one or more offline responses has a JSON format.

6. The method of claim 5, further comprising storing at least some data relationships based on a JSON-formatted online request and one or more JSON-formatted offline responses.

7. The method of claim 1, further comprising receiving instructions for deploying a crawler processing entity to the client device, wherein the crawler processing entity is configured to generate a set of simulated online requests when the client device is connected to an application server.

8. The method of claim 7, wherein the simulated online requests generate additional online activity records for storage in the client-local database are accessible when the client device is disconnected from the application server.

9. The method of claim 1, further comprising receiving instructions for simulating online requests when the client device is connected to the network component.

10. The method of claim 1, further comprising receiving instructions for simulating online requests when the client device is connected to an application server over a network.

11. A computer program product, embodied in a non-transitory computer readable medium, the non-transitory computer readable medium having stored thereon a sequence of instructions which, when stored in memory and executed by a processor causes the processor to execute a process for offline operation of a client application on a client device using a client-local database of online activity records, the process comprising:

receiving, from a networked component, computer code comprising at least a portion of an emulator processing entity to execute on the client device, the emulator processing entity being configured to allocate memory on the client device to store at least one online request and least one online response into a client-local database;

sending one or more online requests from the client application to the networked component;

receiving one or more online responses from the networked component, the online responses to the client application being responsive to at least one of the one or more online requests;

storing, into the client-local database of online activity records, at least one relationship between the one or more online requests and respective one or more online responses; and

using the emulator processing entity to retrieve stored instances of the respective one or more online responses from the client-local database to allow the client to operate in an offline mode when disconnected from the networked component.

12. The computer program product of claim 11, wherein the emulator processing entity is configured to process one or more occurrences of subsequent requests to produce offline responses when the client device is disconnected from a network.

13. The computer program product of claim 12, wherein the emulator processing entity serves to retrieve stored instances of the one or more online responses based at least in part on a one-to-one relationship with the subsequent request.

14. The computer program product of claim 12, wherein the emulator processing entity is configured to deliver one or more offline responses to the client application when the client device is disconnected from an application server.

15. The computer program product of claim 11, wherein one or more online requests and one or more offline responses has a JSON format.

16. The computer program product of claim 15, further comprising instructions to cause the process to store at least some data relationships based on a JSON-formatted online request and one or more JSON-formatted offline responses.

17. The computer program product of claim 11, further comprising instructions to cause the process to receive instructions for deploying a crawler processing entity to the client device, wherein the crawler processing entity is configured to generate a set of simulated online requests when the client device is connected to an application server.

18. The computer program product of claim 17, wherein the simulated online requests generate additional online activity records for storage in the client-local database are accessible when the client device is disconnected from the application server.

19. A system for offline operation of a client application on a client device using a client-local database of online activity records, the system comprising:

a module to receive, from a networked component, computer code comprising at least a portion of an emulator processing entity to execute on the client device, the emulator processing entity being configured to allocate memory on the client device to store at least one online request and least one online response into a client-local database;

a network interface port to send one or more online requests from the client application to the networked component, and to receive one or more online responses from the networked component, the online responses to the client application being responsive to at least one of the one or more online requests;

a client-local database of online activity records to store at least one relationship between the one or more online requests and respective one or more online responses; and

an emulator processing entity to retrieve stored instances of the respective one or more online responses from the client-local database to allow the client to operate in an offline mode when disconnected from the networked component.

20. The system of claim 19, wherein the emulator processing entity is configured to process one or more occurrences of subsequent requests to produce offline responses when the client device is disconnected from a network.
