Abstract

An apparatus for dynamic derivatives desktops and methods of operating the same result in a dynamic derivatives desktop server for a CORBA (Common Object Request Broker Architecture) operating system that processes analytic requests without compromising the analytics of the analysis. The dynamic derivatives desktop server comprises an ORB (Object Request Broker) interface which receives an analytic request from the CORBA operating system. A Java applet coupled to the ORB interface having analytics which processes the analytic request to provide analytic results to the ORB interface.

Claims

1. A dynamic derivatives desktop server in an object-oriented environment, the server comprising:

an object-oriented interface configured to receive an analytic request from an end user client and return results of the analytic request through an object server, wherein the dynamic derivatives desktop server is unknown to the end user client;

an applet depository coupled to the object-oriented interface having a plurality of dyamically modifiable applet resources to provide analytics for processing the analytic request while protecting computational analytics from the end user, wherein a first applet resource that processes the analytic request is maintained in the applet depository after completion of the processing; and

access resources configured to receive a new applet resource for inclusion in the applet depository after receipt of a second analytic request;

wherein the processing of the analytic request is initiated by the object server.

2. The dynamic derivatives desktop server according to claim 1, wherein the analytic request includes client data for the analytics.

3. The dynamic derivatives desktop server according to claim 1, wherein the analytics include derivatives analytics for risk management.

4. The dynamic derivatives desktop server according to claim 3, wherein the applets include Java applets.

5. A distributed object-oriented analytical risk management system on a TCP/IP network having an object-oriented request interface comprising:

a client platform coupled to the TCP/IP network to provide a risk management request to the object-oriented request interface;

a risk management server having analytics which receives the risk management request from the object-oriented request interface and calculates risk results in response to the risk management request; and

an object broker configured to manage the object-oriented request interface, wherein the object broker receives the risk management request from the client platform, identifies one of a set of risk management servers for processing the risk management request, and forwards the risk management request to the risk management server;

wherein the risk management server is unknown to the client platform.

6. The distributed object-oriented analytical risk management system according to claim 5, wherein:

the risk management server provides the risk results to the object-oriented request interface; and

the client platform receives the risk results from the object-oriented request interface through the object broker.

7. The distributed object-oriented analytical risk management system of claim 6, wherein the analytics are loaded onto the risk management server only after the risk management server receives the risk management request.

8. The distributed object-oriented analytical risk management system of claim 6, wherein the calculation of the risk results is initiated by a command from the object broker to the risk management server.

9. The distributed object-oriented analytical risk management system according to claim 7, wherein the risk management server includes a Java applet to provide the analytics to calculate the risk results for the client platform.

10. The distributed object-oriented analytical risk management system according to claim 8, wherein the risk management request includes client data to provide inputs for the analytics of the Java applet.

11. The distributed object-oriented analytical risk management system according to claim 9, wherein the risk management server includes access resources to dynamically configure operation of the Java applet based on an identity of a user operating the client platform.

12. A method of operating an analytical risk management tool in an object-oriented system having an object-oriented request interface comprising the steps:

receiving a request for an analytical risk management calculation at a risk analysis server, said request being received from an object broker and originating from a client, wherein the risk analysis server is unknown to the client;

receiving client data for the analytical risk management calculation;

transferring the client data to a Java applet having analytics to perform the analytical risk management calculation, wherein the Java applet is dynamically upgradeable and is maintained on a permanent storage device;

configuring the Java applet in accordance with an identity of the client,

operating the Java applet to perform the analytical risk management calculation with the client data; and

returning results of the risk management calculation to the object broker for return to the client.

13. The method of operating an analytical risk management tool according to claim 12 further comprising the step isolating the analytics from a client which requests the risk management calculation.

14. The method of operating an analytical risk management tool according to claim 12 further comprising the step configuring dynamically access to the Java applet in response to a particular client.

15. A risk analysis server, comprising:

a first dynamically modifiable risk analysis module comprising computer executable instructions for evaluating a first risk request originating from a remote client computer;

an object interface configured to receive said risk request from a remote intermediate server; and

an access resource configured to receive a second risk analysis module;

wherein said first risk analysis module is executed to evaluate said first risk request and return results of said evaluation to said remote intermediate server; and

wherein said first risk analysis module is retained on the risk analysis server after said execution.

16. The risk analysis server of claim 15, further comprising:

a second risk analysis module received and stored after receipt of a second risk request;

wherein said second risk request is evaluated by executing said second risk analysis module.

17. The risk analysis server of claim 15, wherein said execution of said first risk analysis module is initiated at the direction of said remote intermediate server.

18. The risk analysis server of claim 16, wherein said second risk analysis module replaces said first risk analysis module.

19. A system for receiving and analyzing a risk analysis request using a dynamically updateable risk analysis module, comprising:

a risk analysis server configured to receive risk analysis requests from a broker server, wherein said broker server receives each said risk analysis request from a client computer and determines whether said risk analysis server is capable of handling each said client risk analysis request;

a first dynamically updateable risk analysis module residing on said risk analysis server and comprising computer executable instructions configured to analyze a first risk analysis request received at said risk analysis server; and

an access resource on said risk analysis server configured to receive a second dynamically updateable risk analysis module, wherein said second risk analysis module may augment or replace said first risk analysis module;

wherein one of said first risk analysis module and said second risk analysis module is executed to evaluate said first risk analysis request and return a result of said evaluation to said broker server.

20. The system of claim 19, wherein said first risk analysis request is received at said risk analysis server before either of said first risk analysis module and said second risk analysis module are received at said risk analysis server.

21. The system of claim 19, wherein said execution is triggered by said broker server.

22. A method of evaluating a client risk analysis request, comprising:

receiving at an object broker server a risk analysis request from a client computer, said risk analysis request comprising financial data of a user operating said client computer;

identifying a risk analysis server capable of servicing said risk analysis request;

receiving said risk analysis request at a first risk analysis server from said object broker;

receiving at said first risk analysis server a first risk analysis module comprising computer executable instructions;

storing said first risk analysis module on said first risk analysis server on a permanent storage device;
