can anyone suggest some topics for my project on IBM's The Great Mind Challenge?

To develop the application kindly make use of multiple products. One needs to start with RUP to plan the project effectively. Eclipse should be used to do the coding in Java, DB2 Express C with XML should be used to store and manage the database effectively, WAS CE should be used to host the application. Kindly spend some time in understanding the way WAS CE should be configured and managed for better productivity, and finally do not forget to use TSM to manage the backend database effectively. Once you have used all these products to develop the complete application, your overall understanding of different software tools and their usage for a high end solution development will get enhanced and should be of immense help to  you to work for.
