Abstract: A navigation module for a structured database having a multiplicity of dimensions is operative to cause a user interface to display one or more data point values retrieved from the database and to receive user input. The navigation module responds to user selection of one or more presented data point values by causing the user interface to display a first element indicium representative of an element of one or more data point vectors defining a location of the one or more user selected data point values within the database, and to display a second element indicium associated with the first element. The navigation module retrieves from the structured database one or more new data point values corresponding to one or more new data point vectors defined by user selection of the second element indicium, and causes the user interface to display the one or more new data point values.
