DEVELOPMENT SYSTEM PROVIDING HTML DATABASE CONTROL OBJECT

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.
