A data warehouse is a straightforward definition of database. Data mining technology can be used to process mountains in databases uncover new, fascinating, and useful information.Clustering an approach gathering. As one technique for grouping into clusters or groups, the K-Means Clustering Algorithm algorithm divides those that share cluster's traits don't. so has same grouped cluster. Other a...

We study two generalizations of classic clustering problems called dynamic ordered k-median and k-supplier, where the points that need evolve over time, we are allowed to move cluster centers between consecutive time steps. In these problems, general goal is minimize certain combinations service cost movement centers, or one subject some constraints on other. obtain a constant-factor approximat...
