Abstract:

A system of the present invention includes a relational database management system (RDBMS), having an object-based, interactive visual-programming language providing programming by "visual inheritance. " A user places screen objects (e. g. , boxes, screen buttons, table objects, and the like) on an on-screen window or "form," visually attaches selected "properties" and "methods" to the screen objects, and then establishes an containership-based event model that dictates how and when these properties and methods will be invoked. An object inherits (derives) properties and methods from other (parent) objects via its visual containership. In this manner, the task of creating and maintaining application programs is greatly simplified. An alternative embodiment providing an "Object Explorer" is also described. The Explorer collapses object inspector and object tree functionality into a single UI (user interface) element.

Abstract:

A system for performance testing a web application initializes to be instrumented a subset of methods of the web application to be tested in response to a request, and then tests the application based on the subset of methods. The system generates an instrumented call tree and corresponding stack traces for each request in response to the testing, and determines one or more methods that take longer than a predetermined time period to execute using the instrumented call trees and the stack traces. The system then determines additional methods to be tested and adds the determined additional methods to the subset of methods and repeats the testing.
