A conversion path for converting between two different currencies is defined as a series of simple exchange rate objects and is encapsulated within a compound exchange rate object. The intelligence regarding the specific rules for making the conversion are encapsulated in a policy class, which governs how the path of exchange rates contained in the compound exchange rate is built. When a client requests conversion between two currencies, the compound exchange rate is constructed according to the policy to contain a path of exchange rate objects that may be used to make the requested conversion, and the compound exchange rate is then returned to the client. When the client then instructs the compound exchange rate to make a conversion of a known currency value in the source currency, the compound exchange rate object uses the exchange rate object or objects in the exchange rate path to perform the currency conversion. A system in accordance with the invention thus allows the computation of exchange rates in a fully encapsulated manner according to a predefined policy without the client having to know the details of how the conversion is performed.

Apparatus and method for performing conversion between different units of currency using an encapsulated conversion path of exchange rates

A method and system for diagnosing data-processing system performance. Initially, unique audible sounds are associated with particular performance indicators within the data-processing system. Thereafter, performance indicators are identified, one or more of which indicate data-processing system performance. A diagnostic is then periodically run to detect performance indicators within the data-processing system. A unique audible sound is then generated associated with a particular performance indicator, in response to detecting the status of particular performance indicator via the diagnostic, such that potential data-processing system failures may be recognized by identifying the unique audible sound. The unique audible sound may be continuously generated at varying durations and volumes to indicate the presence of system failures. A trained user, accustomed to particular audible sounds, can identify and diagnose system failures by analyzing unique audible sounds generated by the data-processing system. The frequency and duration of each particular sound may be designated and subsequently altered by the user. The performance indicators may be composed of fault modes, one or more of which may presage data-processing system failures. In addition, the data-processing system itself may be composed of a computer system, such as a personal or mainframe computer.

A method and system for efficiently managing the manipulation of documents too large to be legibly displayed within a computer screen. Initially, a window is provided within which only a portion of an entire document may be displayed legibly. A graphic representation of the entire document is then exhibited within the window. A portion of the graphic representation of the entire document is displayed as a human discernable representation. A remaining portion of the graphic representation of the entire document is displayed as a compressed representation of a portion of the document. The compressed representation is iconic in nature such that a representation nearest the bottom and the top of the document, and furthest away from the human discernable portion, appears as increasingly iconic characters or graphics. The graphic representation itself is composed of a lens bar that allows a user to interpret an entire document displayed within a computer screen at one time on a global scale, while providing the user with an enlarged view of a local area of interest.
