Abstract

A system for integrated support in an XML/XQuery database residing within a binary object XML repository (BOXR) for web-based applications includes web browser(s) for sending at least one HTTP request for hxl pages. Hxl pages are defined as web pages containing embedded XQuery expressions, with XQuery being an interactive program used to access data. Server module(s) coordinate operations within a control system including an XML/XQuery database. An hxl processor module provides web application support, and a BOXR XQuery engine processes XQuery queries. An XML repository provides stored representation of XML data.

Claims

1. A system for integrated support in an XML/XQuery database residing within a binary object XML repository (BOXR) for web-based applications, comprising:

at least one web browser for sending at least one HTTP request for hxl pages, wherein hxl pages comprise web pages containing embedded XQuery expressions, and wherein XQuery is an interactive program used to access data;

at least one server module for coordinating operations within a control system including at least one XML/XQuery database;

at least one hxl processor module for providing web application support;

at least one BOXR XQuery engine for processing at least one XQuery query; and

at least one XML repository for providing stored representation of XML data.

2. The system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein coordinating operations within a control system including at least one XML/XQuery database comprises reviewing said at least one HTTP request and routing said at least one HTTP request.

3. The system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein providing web application support comprises retrieving the values of cookies and HTTP parameters, wherein said cookies comprise text files managed by said web browser to store information associated with particular websites.

4. The system for integrated support in an XML/XQuery database for web-based applications according to claim 3, wherein providing web application support further comprises binding cookie values and HTTP request parameters to global XQuery variables.

5. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein providing web application support comprises appending remaining text preceding an XQuery section to the end of a specified web page.

6. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein providing web application support comprises extracting said XQuery section, discarding said XQuery section, and replacing said discarded XQuery section with the XQuery evaluation results.

7. The system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein processing said at least one XQuery query comprises:

receiving said at least one XQuery query;

evaluating said at least one XQuery query; and

returning XQuery engine evaluation results to said HXL processor module.

8. The system for integrated support in an XML/XQuery database for web-based applications according to claim 1, wherein providing web application support further comprises inserting XQuery engine evaluation results in specified locations in said HXL pages.

9. A method for operating a system for integrated support in an XML/XQuery database residing within a binary object XML repository (BOXR) for web-based applications, wherein said system includes a web browser, a server module, an hxl processor module, a BOXR/XQuery engine module, and an XML repository, the method comprising:

receiving at least one HTTP request for hxl pages from the web browser, wherein said hxl pages comprise web pages containing embedded XQuery expressions;

coordinating operations within a control system having at least one XML/XQuery database;

providing web applications support utilizing at least one hxl processor module;

evaluating at least one XQuery query utilizing at least one BOXR XQuery engine; and

providing stored representation of XML data in at least one XML repository.

10. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein coordinating operations within a control system including at least one XML/XQuery database comprises reviewing said at least one HTTP request and routing said at least one HTTP request.

11. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein providing web application support comprises appending remaining text preceding an XQuery section to the end of a specified web page.

12. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein providing web application support comprises extracting said XQuery section, discarding said XQuery section, and replacing said discarded XQuery section with the XQuery evaluation results.

13. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein providing web application support comprises retrieving the values of cookies and HTTP parameters, wherein said cookies comprise text files managed by said web browser to store information associated with particular websites.

14. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 11, wherein providing web application support further comprises binding cookie values and HTTP request parameters to global XQuery variables.

15. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein evaluating said at least one XQuery query comprises:

receiving said at least one XQuery query;

evaluating said at least one XQuery query; and

returning XQuery engine evaluation results to said HXL processor module.

16. The method for operating a system for integrated support in an XML/XQuery database for web-based applications according to claim 9, wherein providing web application support further comprises inserting XQuery engine evaluation results in specified locations in said HXL pages.

17. An article of manufacture comprising a computer usable medium having computer readable program code embodied in said medium which, when said program code is executed by said computer causes said computer to perform method steps for operating a system for integrated support in an XML/XQuery database residing within a binary object XML repository (BOXR) for web-based applications, wherein said system includes a web browser, a server module, an hxl processor module, a BOXR/XQuery engine module, and an XML repository, the method comprising:

receiving at least one HTTP request for hxl pages from the web browser, wherein said hxl pages comprise web pages containing embedded XQuery expressions;

coordinating operations within a control system having at least one XML/XQuery database;

providing web applications support utilizing at least one hxl processor module;

evaluating at least one XQuery query utilizing at least one BOXR XQuery engine; and

providing stored representation of XML data in at least one XML repository.
