dc.description.abstractWE CONSIDER THE PROBLEM OF MINING FOR FUNCTIONAL DEPENDENCIES IN RELATIONAL DATABASES. INTERMEDIATE DATA STRUCTURES, ALTHOUGH SIMPLE, EXPLODE IN SIZE AND A SOLUTION IS PROPOSED USING RADIX TREES TO REDUCE MEMORY UTILIZATION. PARALLELISM IS FURTHER APPLIED IN A MULTI-CORE COMPUTER TO FURTHER SPEEDUP THE PROCESS. BECAUSE BIT-PERMUTATIONS ARE THE BASIS OF THE CONSTRUCTION OF A BINARY INTERMEDIATE MATRIX, RADIX TREES REDUCE THE MEMORY USAGE 10 TIMES. MULTI-THREADING THE CONSTRUCTION AND PROCESSING OF THE INTERMEDIATE DATA LEADS TO A CONCURRENT COMPUTING AVERAGE-OVER-TIME OF 63 % ON AN EQUIVALENT SPEEDUP OF 6.3 ON A SYSTEM WITH 12 CORES, 256 GB OF MEMORY AND 1 TB SSD.
