Abstract

Data-driven applications are often designed to couple with a remote data store, such as a relational database server. It may be difficult for developers to implement complex details of the synchronization, including data caching and concurrency management, and developers may be unable to use synchronization code libraries without specialized knowledge of such issues. A data-binding model may be provided to simplify the developer'"'"'s task of coupling a class in a data-driven application with a remote data store. The development platform may allow the developer to specify the data-bound properties of a class and the aspects of a remote data store for the binding relationship, and may automatically reconfigure the class to implement the many details of binding to the remote data store.

Claims

1. A computer-implemented method of fulfilling a request to bind a class to a remote data store, the method comprising:

configuring the class to create a local cache configured to synchronize with the remote data store, and

configuring the class to bind instances of the class to the local cache.

2. The method of claim 1, the request specifying the remote data store, at least one bound property of the class, and at least one aspect of the remote data store to store in the local cache and bind to the at least one bound property of the class.

3. The method of claim 1, the binding comprising binding at least one property of the instances of the class to at least one aspect in the remote data store.

4. The method of claim 3, the binding comprising at least one of:

setting the bound property of the instances of the class to the aspect in the remote data store, and

setting the aspect in the data store to the bound property of the instances of the class.

5. The method of claim 1, the local cache configuring comprising:

structuring the local cache according to at least a portion of a schema of the remote data store.

6. The method of claim 1, the local cache configuring comprising:

structuring the local cache according to at least one bound property of the class.

7. The method of claim 1, the local cache configuring comprising:

structuring the local cache according to at least one data set returned by a synchronization query.

8. The method of claim 1, comprising:

configuring the local cache to synchronize with the remote data store periodically.

9. The method of claim 1, comprising:

configuring the local cache to synchronize with the remote data store upon receiving a synchronization request.

10. The method of claim 1, comprising:

configuring the local cache to synchronize with the remote data store upon reconnecting to the remote data store after an interrupted connection.

11. The method of claim 1, comprising:

configuring the local cache to subscribe to the remote data store for receiving updates to the remote data store.

12. The method of claim 1, comprising:

upon receiving at least one synchronization attribute, configuring the local cache to synchronize with the remote data store using the synchronization attribute.

13. The method of claim 12, the synchronization attribute comprising at least one of a connection parameter, a synchronization frequency, a synchronization query, and a synchronization rule.

14. The method of claim 1, comprising:

connecting the local cache to a local cache query processor configured to process queries on the data stored in the local cache.

15. A computer-readable medium comprising processor-executable instructions configured to perform a method of fulfilling a request to bind a class to a remote data store, the method comprising:

configuring the class to create a local cache configured to synchronize with the remote data store, and

configuring the class to bind instances of the class to the local cache.

16. A system for fulfilling a request to bind a class to a remote data store, the system comprising:

a local cache creating component configured to create a local cache configured to synchronize with the remote data store, and

a binding component configured to bind instances of the class to the local cache.

17. The system of claim 16, the request specifying the remote data store, at least one bound property of the class, and at least one aspect of the remote data store to store in the local cache and bind to the at least one bound property of the class.

18. The system of claim 16, comprising:

a synchronization attribute component configured to receive at least one synchronization attribute and to configure the local cache to synchronize with the remote data store using the synchronization attribute.

19. The system of claim 18, the synchronization attribute comprising at least one of a connection parameter, a synchronization period, a synchronization query, and a synchronization rule.

20. The system of claim 16, comprising:

a local cache query processor configured to process queries on the data stored in the local cache.
