Abstract

A view component of an application requests content from a model component of the application, where the request for content includes a request for data. The model component determines whether the requested data is available. If the requested data is available, the model component delivers the requested content and the requested data. If the requested data is not available, the model component first delivers the requested content and a data placeholder, and after the model component retrieves the data, the model component delivers the requested data to replace the data placeholder.

Claims

1. A non-transitory computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to deliver content to a user interface of an application, the delivering comprising:

receiving a request for content, wherein the request comprises a request for data;

determining whether the requested data is available, wherein the requested data is available when the data is cached in a memory;

transmitting the requested content and the requested data in a single communication when the requested data is available, wherein the requested content and the requested data are displayed within the user interface of the application;

transmitting the requested content and a data placeholder in a first communication when the requested data is not available, wherein the requested content and the data placeholder are displayed within the user interface of the application, wherein the data placeholder is displayed in place of the requested data, and wherein the data placeholder indicates that the requested data is being retrieved;

retrieving the requested data from a data store when the requested data is not available; and

transmitting the requested data in a second communication when the requested data is not available, wherein the requested data is displayed in place of the data placeholder within the user interface of the application;

wherein the requested data is delivered according to a content delivery attribute, and wherein the content delivery attribute defines when the requested data is delivered.

2. The non-transitory computer-readable medium of claim 1, wherein the determining whether the requested data is available further comprises invoking one or more methods of a content delivery application programming interface, wherein the content delivery application programming interface comprises one or more instructions for determining whether the requested data has been cached in a memory.

3. The non-transitory computer-readable medium of claim 1, wherein the requested data comprises a range of rows of data.

4. The non-transitory computer-readable medium of claim 1, wherein the application comprises a model layer and a view layer, the model layer comprises a model component, and the view layer comprises a view component;

wherein the model component receives the request for content from the view component;

wherein the model component determines whether the requested data is available within the model component without retrieving the data from the data store;

wherein the model component transmits the requested content and the requested data to the view component in the single communication when the requested data is available;

wherein the model component transmits the requested content and the data placeholder to the view component in the first communication when the requested data is not available;

wherein the model component retrieves the requested data from the data store when the requested data is not available; and

wherein the model component transmits the requested data to the view component in the second communication when the requested data is not available.

5. The non-transitory computer-readable medium of claim 1, wherein the content comprises a web page that comprises one or more tables, trees, or tree tables.

6. The non-transitory computer-readable medium of claim 1, wherein the content comprises a user interface screen that comprises one or more tables, tree, or tree tables.

7. The non-transitory computer-readable medium of claim 1, wherein the data comprises data that is stored in the data store.

8. The non-transitory computer-readable medium of claim 1, wherein the data placeholder comprises text or an image.

9. The non-transitory computer-readable medium of claim 1, wherein the first communication is a separate communication from the second communication.

10. The non-transitory computer-readable medium of claim 1, wherein the content delivery attribute defines the requested data to be delivered:

(a) at the same time that the requested content is delivered;

(b) after the requested content is delivered;

or (c) at the same time that the requested content is delivered when the requested data is available and after the requested content is delivered when the requested data is not available.

11. The non-transitory computer-readable medium of claim 1,

wherein the requested data comprises a range of rows of data;

wherein a method of a content delivery application programming interface is invoked and the range of rows of data is passed as a parameter of the method; and

wherein it is determined whether the range of rows of data is cached within the memory.

12. The non-transitory computer-readable medium of claim 11, wherein a number of rows of the requested data is limited by a pre-determined fetch size attribute.

13. A computer-implemented method for delivering content to a user interface of an application, the computer-implemented method comprising:

receiving a request for content, wherein the request comprises a request for data;

determining whether the requested data is available, wherein the requested data is available when the data is cached in a memory;

transmitting the requested content and the requested data in a single communication when the requested data is available, wherein the requested content and the requested data are displayed within the user interface of the application;

transmitting the requested content and a data placeholder in a first communication when the requested data is not available, wherein the requested content and the data placeholder is displayed within the user interface of the application, wherein the data placeholder is displayed in place of the requested data, and wherein the data placeholder indicates that the requested data is being retrieved;

retrieving the requested data from a data store when the requested data is not available; and

transmitting the requested data in a second communication when the requested data is not available, wherein the requested data is displayed in place of the data placeholder within the user interface of the application

wherein the requested data is delivered according to a content delivery attribute, and wherein the content delivery attribute defines when the requested data is delivered.

14. The computer-implemented method of claim 13, wherein the determining whether the requested data is available further comprises invoking one or more methods of a content delivery application programming interface, wherein the content delivery application programming interface comprises one or more instructions for determining whether the requested data has been cached in a memory.

15. The computer-implemented method of claim 13, wherein the requested data comprises a range of rows of data.

16. The computer-implemented method of claim 13, wherein the application comprises a model layer and a view layer, the model layer comprises a model component, and the view layer comprises a view component;

wherein the model component receives the request for content from the view component;

wherein the model component determines whether the requested data is available within the model component without retrieving the data from a data store;

wherein the model component transmits the requested content and the requested data to the view component in the single communication when the requested data is available;

wherein the model component transmits the requested content and the data placeholder to the view component in the first communication when the requested data is not available;
