Abstract: The current invention relates to a method of identifying relevant records in a database, preferably of determining potentially fraudulent records in said database. A graphical user interface is provided to a user to display multiple inputs, to receive inputs from the user and to display results. A first detection strategy targeted to detect existing records from the database is defined. The first detection strategy comprises multiple first inputs that comprise at least one threshold, at least one detection method, at least one weighting factor, and at least one parameter. The first inputs can be individually displayed on said graphical user interface for each of the at least one detection method. The first inputs can preferably be individually set for each of the at least one detection method. A second detection strategy targeted to detect said existing records from the database is defined. The second detection strategy comprises multiple second inputs.
