Abstract: A method and system for efficiently handling events occurring in an environment in a data processing system. The data processing system includes multiple environments and objects that may be used in different environments. Each object includes an action that is triggered in response to an event. An event manager object is created for handling events from different environments. Events are registered for the objects. An action is triggered using the event manager object in response to detecting an event occurring in the data processing system, wherein events occurring in an environment are efficiently handled.

Abstract: A method and system for debugging an object from a plurality of objects forming an application in an object oriented system utilizing a graphic user interface. A number of the objects forming the application may include one or more action slots with each action slot containing one or more action objects. The present invention stores each action object with an action slot in an activation object in response to an event generated by user utilizing the graphic user interface. The event is associated with an action slot. Data sent to each action object is stored in the activation object. The data is data required to recreate the event caused by the user. Each time an event is generated, an activation object is created. These activation objects may be debugged utilizing a debugger.

Abstract: A search facility having a user interface including three windows: a query window, a graph window and a history window. Each of the windows is presented simultaneously in the graphical user interface. The query window displays the text of the most recently input query statement which is searched in a database stored in a computer system. The graph window graphically displays the current results of the most recent query statement. The history window presents the query statements and their results during the current query session. In one preferred embodiment, the query statements and their results are graphically presented as a tree, wherein the query statements and query results are nodes and each query statement result is a child of the query statement which was run to create it. Input to any of the windows will change the presentation of data within the other two windows.

Abstract: An apparatus for modifying a database query including apparatus for graphically displaying in at least two dimensions data obtained from a database by the database query, apparatus for selecting at least one portion of the graphically displayed data, and apparatus for modifying the database query according to the selected portion of the graphically displayed data. In addition, a method for modifying a database query including the steps of graphically displaying in at least two dimensions data obtained from a database by the database query, selecting at least one portion of the graphically displayed data, and modifying the database query according to the selected portion of the graphically displayed data.
