Abstract

A Database Development System is described that provides methodologies for creating an HTML or Web database control object (the “HTML DataWindow”) for use in a Client/Server Database System The HTML DataWindow serves as a thin-client DataWindow implementation for Web applications that provides most of the data manipulation, presentation, and scripting capabilities of the PowerBuilder DataWindow, without requiring any runtime DLLs (e.g., PowerBuilder runtime dynamic link libraries) on the client. DataWindow validation rules, formatting, and edit styles are automatically converted by the system into equivalent HTML and JavaScript, without coding by the user. HTML is generated that is suitable for the target browser. A plurality of functions and events are implemented by the generation of JavaScript which is downloaded to the client. In this manner, the Web or HTML DataWindow Design-Time Dontrol supports generation of a runtime DataWindow object in HTML.

Claims27

Dependent claims

A method for providing a Web-based database control object, the method comprising:

at design time, creating a definition of a Web-based database control object based on input of a developer user for visually dropping a data window design time control object corresponding to said Web-based database control object onto an HTML editing surface and using said data window design time control object for receiving input of the developer user for modifying properties of said Web-based database control object as appropriate for data access;
receiving at a Web server a request from an end user's Web browser for a particular Web page;
passing the request to a page server;
at the page server, locating a Web page template for the requested Web page, said Web page template including a definition of the Web-based database control object;
executing server-side scripts in said Web page template, said server-side scripts establishing a connection to a server component and passing to the server component information about said Web-based database control object;
at the server component, performing substeps of:
establishing a connection with a database,
retrieving data required for said Web-based database control object from the database,
based on said definition of said Web-based database control object, generating hypertext markup language and script commands for rendering said Web-based database control object at the end user's browser, and
returning said generated hypertext markup language and script commands to the page server;
at the page server replacing the server-side script in the requested Web page with the generated hypertext markup language and script commands;
and
returning the page to the end user's Web browser, said page rendering said Web-based database control object with data from said database, such that rendering said Web-based database control object in the end user's Web browser occurs without requiring a runtime library at the end user's Web browser.

10 more elements

A development system providing a Web based database control object that allows an end user to manipulate, from an HTML browser, data that resides in a database, said development system comprising:

program logic for defining at design time a Web-based database control object definition, said definition based at least in part on a developer visually dropping a data window design time control object corresponding to said Web-based database control object onto an HTML editing surface and based in part on a developer using said data window design time control object to set properties of said Web-based database control object, said definition including specification of retrieval of information from the database;
program logic for generating at runtime, based on said Web-based database control object definition, HTML and script commands for rendering a user interface for displaying said information specified by said Web-based database control object in an HTML browser, including generating said user interface in accordance with a presentation style specified in said Web-based database control object and displaying said information from said database in said user interface;
wherein said HTML and script commands provide, at least in part, runtime program logic that allows the end user to make modifications to said information displayed in said user interface by said Web-based database control object;
wherein said HTML and script commands provide, at least in part, runtime program logic that allows the end user to apply said modifications to said database;
and
wherein displaying said information specified by said Web-based database control object in the HTML browser occurs without requiring a runtime library at the HTML browser.
