Abstract

Systems, methods and computer program products for dynamically binding data from a remote data source in a container-based mobile application are described herein. The method includes the steps of: 1) defining a metadata source that references both a mobile business object (MBO) and the mobile application, the MBO being connected to the remote data store; 2) binding an attribute from the MBO to the mobile application using the metadata source; and 3) changing, dynamically, the binding of the attribute while the mobile application is executing.

Claims

1. A computer implemented method of dynamically binding data from a remote data store to a mobile application executed on a mobile device, comprising:

defining a metadata source that references both a mobile business object (MBO) and the mobile application, wherein the MBO is connected to the remote data store;

binding an attribute from the MBO to the mobile application using the metadata source; and

changing, dynamically, the binding of the attribute while the mobile application is executing.

2. The computer-implemented method of claim 1, wherein the mobile application is a container-based mobile application.

3. The computer-implemented method of claim 1, wherein the metadata source stores binding information in extensible markup language (XML).

4. The computer-implemented method of claim 1, wherein the mobile application is an XML business object executed within an XML business object container.

5. The computer-implemented method of claim 1, further comprising:

limiting data received by the mobile application from the MBO based on subscription criteria stored in the metadata source.

6. The computer-implemented method of claim 1, wherein binding an attribute comprises:

linking, in the metadata source, data referenced by the MBO to a user interface control of the mobile application.

7. The computer-implemented method of claim 1, wherein the mobile application comprises both a client side and server-side component, and wherein the metadata source is referenced by the server-side component to set bindings to the MBO.

8. A system of binding data from a remote data store in a mobile application comprising:

a first component of the mobile application, the first component configured to be executed on a computer server, wherein the first component is configured to be operatively connected to a second component of the mobile application, the second component being operated on a mobile device;

an abstraction layer for accessing data in the remote data source, the abstraction layer and the first component being operatively connected; and

a metadata source configured to map data referenced in the abstraction layer to the mobile application, wherein the mapping in the metadata source may be changed while the mobile application is executing.

9. The system of claim 8, wherein the abstraction layer is a mobile business object.

10. A system to allow a mobile application to subscribe to a mobile business object comprising:

a data source stored on a first computer server;

an abstraction layer operatively connected to the data source;

a first component of the mobile application, the first component configured to be executed on a second computer server, wherein the first component is operatively connected to the abstraction layer and a second component of the mobile application, the second component being operated on a mobile device; and

a metadata source configured to contain subscription criteria, wherein the subscription criteria determines data transferred from the first component to the second component.

11. The system of claim 10, wherein the first component is further configured to request information from the abstraction layer based on the subscription criteria.

12. The system of claim 10, wherein the first component is further configured to transmit the subscription criteria to the abstraction layer.

13. The system of claim 10, wherein the abstraction layer is a mobile business object (MBO).

14. The system of claim 10, further comprising:

requesting with the first component, based on the subscription criteria, a first portion of data from the abstraction layer; and

communicating a second portion of data to a second component of the mobile application, wherein the second portion is derived from the first portion based on the subscription criteria and characteristics of second component is installed on a mobile device.

15. A method of subscribing to a mobile business object in a mobile application, comprising:

creating a first component of a mobile application;

creating a metadata source configured to contain subscription criteria, the subscription criteria defining data to be retrieved to support the mobile application;

requesting with the first component, based on the metadata source, a first portion of data from the mobile business object; and

communicating a second portion of data to a second component of the mobile application, wherein the second portion is derived from the first portion based on the metadata store and the second component is installed on a mobile device.
