Předzpracování databázových dat pro následný datamining

Abstract

The bachelor´s thesis deals with database data preprocessing and determining their final form so that data mining can be obtained through appropriate software. To ensure that the objectives of the work are fulfilled we describe the basic principles of relational databases, construction of the entity relationship diagrams and data flow diagrams. The issue is demonstrated on real data from the heating rotary hearth furnace at the ŽD Bohumín. At the same time was described the database with the help of relevant diagrams and suggest a method for verifying the data.
