Kumar, P.Ananthanarayana, V.S.2020-03-302020-03-302012Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2012, Vol.6411 LNCS, , pp.333-340https://idr.nitk.ac.in/handle/123456789/7411The abstraction based algorithms read databases in sequential order and then construct abstraction of the database in memory. Given any database with n attributes, it is possible to read the same in n! ways. These different n! ways lead to abstractions of different sizes. In this paper, for a given a set of transactions D, we find the sequence or order of the attributes in which the database is read, a representation which is compact than PC-tree, can be obtained in the memory. � 2012 Springer-Verlag.Book chapter
