Abstract:
A computer-implemented Rapid Application Development (RAD) tool for constructing client-server applications comprised of first, second, and third tier programming logic for a three tier computer network architecture, the RAD tool comprising:a first window module for displaying the first tier programming logic, the first tier programming logic comprising a web browser capable of containing and executing applets, wherein the first tier programming logic communicates with the second and third tier programming logic;a second window module for displaying the second tier programming logic, the second tier programming logic comprising one or more second tier application scripts executed by a second tier runtime module that interfaces to a web server, wherein the second tier programming logic communicates with the first and third tier programing logic;a third window module for displaying the third tier programming logic, the third tier programming logic comprising one or more third tier application scripts executed by a third tier runtime module that interfaces to a database management system, wherein the database management system receives requests from the second tier programming logic and the third tier runtime module, performs database functions in response to the requests, and returns results from the performed database functions;so that as a user interacts with the first tier programming logic in the first window module, the second and third tier programming logic are executed in response thereto, breakpoints are selectively triggered within the executed second and third tier programming logic, and the selectively triggered breakpoints are displayed in the second and third window modules, respectively.
