call the server computing system through an application programming interface exposed by the server computing system; and

receive a set of section metadata for each of a plurality of different user interface displays.

11. The computing system of claim 9 wherein the instructions, when executed, configure the computing system to:

identify a section to be displayed on the user interface display; and

control the server connection component to call the server computing system for the section metadata for the identified section.

12. The computing system of claim 11 wherein the instructions, when executed, configure the computing system to:

identify the section to be displayed by determining a section identifier identifying the section to be displayed, an entity type for which the user interface display is to be displayed, and a set of identifying data that identifies the data bound to the section to be displayed.

13. The computing system of claim 11 wherein the instructions, when executed, configure the computing system to:

identify an application context of the client application running on the computing system; and

call the server computing system based on the application context.

14. The computing system of claim 13 wherein the instructions, when executed, configure the computing system to:

identify the section to be displayed by determining a device type identifier that identifies a device type of a device on which the computing system is deployed and a user identity identifying the user of the device.

15. The computing system of claim 14 wherein the instructions, when executed, configure the computing system to:

call the server computing system with the section identifier, the entity type, the identifying data, the application context, the device type and the user identity.

16. The computing system of claim 13 wherein the instructions, when executed, configure the computing system to:

parse the section metadata to identify rendering information; and

render the section on the user interface display based on the rendering information.

17. A computer implemented method, comprising:

receiving, by a computing system, a call from a client application associated with a client computing device that is separate from the computing system, the call

being associated with a user interface display, and

including section identifying metadata;

based on the section identifying metadata received in the call, identifying a plurality of different sections that are each predefined on the user interface display;

identifying user interface control metadata indicative of a user interface control on each section of the identified plurality of different sections;

identifying data binding metadata that corresponds to each section of the identified plurality of different sections and indicates data bound to each of the user interface controls; and

returning, by the computing system to the client computing device, section rendering metadata comprising the control metadata and the data binding metadata.
