Abstract: Database clustering is now a widely used technique in DBMS, data warehousing, and data mining in contemporary scientific research. Clustering analysis plays an essential part in database technological development across the globe as a reference component of the database. Clustering covers the segmentation and deeper comprehension of the data structure in an unknown area, and is regarded as a critical problem for unsupervised learning. Due to its wide range of applications, clustering analysis has become a hot topic in data mining research. The popularity of data clustering algorithms has risen in recent years as a result of their widespread usage in a number of applications, including image processing, computational biology, mobile communication, medicine, and economics. The main issue with data clustering techniques is that they are not standardised. The main goal of cluster analysis is to keep objects in a cluster closer together than things belonging to other groups or clusters with similar characteristics, which are referred to as clusters. Its goal is to examine, evaluate, and analyse a few of the clusters that fall into the different cluster paradigm categories, as well as to offer a thorough comparison of efficiency, benefits, and drawbacks for a few common causes. This research also contributes to the correlation of certain key characteristics of an effective clustering method.
