A system includes a database with a plurality of records, each record including a plurality of data fields. The system receives input from an end user. The end user input is received via an end user interface, and the end user input includes a subset of the plurality of data fields. The system queries the database using the subset of data fields, and data is retrieved from the database using the subset of data fields. The data retrieved from the database substantially include only data fields that are the data fields supplied by the end user.
