In early phases of development it was noticed that giving names to the data components helped considerably the data mining task. In ENTIRE, instead of having either to memorize the vector component order or to check the component name from a separate list, the names of the vector components are always displayed along with the vector. Another aspect which helps the user in data mining is the possibility to divide the vector components into groups. When a data vector is shown, the vector components are displayed in blocks so that all components belonging to a certain group are in one block as shown in figure 4.1.
