System and method for application development and deployment

A method of using a web portal for application development and execution, the method comprising:

• downloading a copy of a runtime engine on a client computing system, the runtime engine comprising at least one predefined structure, the client computing system becoming a rich client computing system on receiving the copy of the runtime engine;
• developing an application for an intended functionality, on at least one of the web portal and the client computing system, wherein the developed application includes plurality of components;
• compiling the plurality of components of the application for the intended functionality using the runtime engine present at the web portal, the compiling step further comprises transmitting a plurality of components specific parameter information from the web portal to the rich client computing system;
• executing the application for the intended functionality, on the web portal using the rich client computing system, wherein the executing the application comprises:
• linking the transmitted component parameter information to a predefined structure at the rich client computing system to provide a script specific predefined structure, the predefined structure having an intended functionality corresponding to the intended functionality of the requested component;
• and
• executing the script specific predefined structure to execute the component;
• and
• executing a part of the application, that cannot be executed on the rich client computing system, on the web portal, whereby the rich client computing system enables usage of minimal network bandwidth and server resources.
