Top-K

The Java library file for the first project (p5) is available through the link below:

http://www-student.cse.buffalo.edu/~dlessa/cse462-SP10/topK.jar


About the library:

• TopKImpl is the skeleton class that you must implement. It is a stub that implements the TopK interface. You may create any number of helper methods in this class.
  

• ScoringFunction is the interface that defines the signature of a scoring function. A sample implementation of scoring function, ScoringFunctionImpl, is provided for you to test your implementation.

• Tuple is a simple class that extracts and encapsulates a single tuple from a ResultSet object.
  

• OraConnectionProxy is a helper class for you to connect to Oracle. Use if you like it. First, you must modify the user name and password in order to connect to Oracle.

• Launcher has a main method that you can use to test your implementation. Two queries are provided with code calling your Top-K implementation. Test data is available to help you check if your algorithm is running correctly (the data has been commented out).
