abstract = {Knowledge discovery in databases is the non-trivial process of indentifing valid, novel, useful and understandable patterns in data. Relational data mining is a step in the knwoledge discovery process concerned with finding relational patterns in data. Realtional data minig algorithms are capable of directly dealing with multiple relations found in relational databases. In this paper we discuss methods that transform a relational data into an attribute-value representation. These approaches are based on the rough set methodology.},
