This paper proposes a clustering technique that minimizes the need for subjective human intervention and is based on elements of rough set theory(RST).The proposed algorithm is unified in its approach to clustering and makes use of both local and global data properties to obtain clustering solutions.It handles single-type and mixed attribute data sets with ease.The results from three data sets of single and mixed attribute types are used to illustrate the technique and establish its efficiency.
