Abstract

A component object binds business driven services to a graphical user interface (GUI). The object includes a data model, view model and controller. The view model graphically presents, and the controller manipulates data used by the object. The controller includes an event handler that respond to events generated within the GUI and binds data used by the object to a data source which can be another component object or a remotely located source. The event handler can call a local script to calculate the value of a data element within the object. The component object can be instantiated on a client, and can be configured to communicate with a corresponding component object on a server. The client and server component objects can exchange only that data that needs to be exchanged to maintain the current state of a user interface in the client computer.

Dependent claims

A system, comprising:

a server-computer configured to run different server applications, the different server applications having diverse data models and logics;
and
a user interface (UI) component object having a declarative interface for binding to the different server applications having diverse data models and logics running on the server-computer,
wherein the UI component object is configured for common instantiation in a server-computer runtime and in a client-computer runtime on a client computer,
wherein the UI component object has a universal data structure abstracted from the different data models and logics of the different server applications,
wherein the universal data structure includes:
a data model for representing data used by the UI component object;
a view model for graphically presenting the data used by the UI component object;
and
a controller for manipulating the data used by the UI component object, the controller including an event handler configured to respond to events generated within a graphical user interface on the client computer,
wherein the server-computer is configured to write, interpret, and translate data of the different server applications having diverse data models and logics to the universal data structure in the UI component object, and
wherein the event handler is configured to respond to an event within the graphical user interface by calling a local script to calculate a value of a data element within the component object.

A system comprising:

a client computer;
and
a graphical user interface configured to host, in client-computer runtime, an instantiation of a user interface (UI) component object bound to a first server application running on a server-computer and configured for common instantiation in a server-computer runtime,
wherein the UI component object has a declarative interface for binding to different server applications having diverse data models and logics running on the server-computer,
wherein the UI component object has a universal data structure abstracted from the diverse data models and logics of the different server applications available on the server-computer,
wherein the universal data structure includes:
a data model for representing application data used by the UI component object;
a view model for graphically presenting the application data used by the UI component object;
and
a controller for manipulating the application data used by the UI component object, the controller including an event handler configured to respond to events generated within the graphical user interface,
wherein the UI component object instantiation on the graphical user interface is bound to the first server application running on the server-computer via communication links to a counterpart UI component object instantiation on the server-computer, and
wherein the event handler is configured to respond to an event within the graphical user interface by calling a local script to calculate a value of a data element within the component object.
