Abstract

A user-friendly query modeling tool for representing creating, modifying and modeling a query language statement for use in retrieving data from a database. In accordance with the present invention, the tool includes a user interface for receiving or building and manipulating a query, a query model definition for use in populating instances of one or more query models, and a model content provider for receiving query elements from the user interface and providing them to the query model, and conversely, for retrieving query elements from the query model and providing them to the user interface. The model content provider has a hierarchical architecture including lower level API specific components for supporting a plurality of GUI API'"'"'S, and higher level API-independent, reusable components. This architecture facilitates scalability in terms of adding support for new API'"'"'s.

Claims

1. A computer system to support a plurality of graphical user interface (GUI) application programming interfaces (APIs), the computer system comprising:

a processor executing a query assist tool, the processor being a hardware component within the computer system, the query assist tool comprising;

a model content provider in communication with a query model, the query mode comprising a plurality of elements that represents a database statement, wherein the model content provider translates a plurality of elements of a query model into objects that are independent of any type of data structure associated with the plurality of GUI APIs, the plurality of elements being translated through use of a model content provider in communication with the query model, the plurality of elements representing a database statement;

a first content viewer in communication with the model content provider, the first content viewer supporting multiple GUI APIs, wherein the first content viewer passes the translated objects from the model content provider to a first content viewer in communication with the model content provider, the first content viewer supporting multiple GUI APIs; and

a second content viewer in communication with the first content viewer and an application written to run on a specific GUI API of the plurality of GUI APIs, wherein the translated objects are passed from the first content viewer to the second content viewer, and wherein the second content viewer manipulates the translated objects into one or more types of data structures required by the specific GUI API for use by the application.

2. The computer system of claim 1 wherein the one or more types of data structures comprise tables, trees, or lists.

3. The computer system of claim 1 wherein the database statement is a structured query language (SQL) statement.

4. The computer system of claim 1 wherein the model content provider:

receives information from the application via the first content viewer and the second content viewer at the model content provider, the received information being independent of any type of data structure; and

creates one or more additional elements using the model content provider based on the received information responsive to the received information being an addition to the plurality of elements in the query model.

5. The computer system of claim 1 wherein the model content provider:

receives information from the application via the first content viewer and the second content viewer at the model content provider, the received information being independent of any type of data structure; and

removes one or more of the plurality of elements from the query model using the model content provider responsive to the received information being a deletion of the one or more elements in the query model.

6. The computer system of claim 1 wherein the model content provider provides both data and image information for each of the plurality of elements in the query model to the first content viewer using the model content provider.

7. A computer-readable medium including program instructions for supporting a plurality of graphical user interface (GUI) application programming interfaces (APIs), the program instructions which when executed by a computer system cause the computer system to execute a method comprising:

translating a plurality of elements of a query model into objects that are independent of any type of data structure associated with the plurality of GUI APIs, the plurality of elements being translated through use of a model content provider in communication with the query model, the plurality of elements representing a database statement;

passing the translated objects from the model content provider to a first content viewer in communication with the model content provider, the first content viewer supporting multiple GUI APIs;

passing the translated objects from the first content viewer to a second content viewer, the second content viewer being in communication with the first content viewer and an application written to run on a specific GUI API of the plurality of GUI APIs; and

using the second content viewer to manipulate the translated objects into one or more types of data structures required by the specific GUI API for use by the application.

8. The computer-readable medium of claim 7 wherein the one or more types of data structures comprise tables, trees, or lists.

9. The computer-readable medium of claim 7 wherein the database statement is a structured query language (SQL) statement.

10. The computer-readable medium of claim 7 further comprising program instructions for:

receiving information from the application via the first content viewer and the second content viewer at the model content provider, the received information being independent of any type of data structure; and

creating one or more additional elements using the model content provider based on the received information responsive to the received information being an addition to the plurality of elements in the query model.

11. The computer-readable medium of claim 7 further comprising program instructions for:

receiving information from the application via the first content viewer and the second content viewer at the model content provider, the received information being independent of any type of data structure; and

removing one or more of the plurality of elements from the query model using the model content provider responsive to the received information being a deletion of the one or more elements in the query model.

12. The computer-readable medium of claim 7 further comprising program instructions for providing both data and image information for each of the plurality of elements in the query model to the first content viewer using the model content provider.
