A time efficient and accurate retrieval of range aggregate queries using fuzzy clustering means (FCM) approach

Abstract

Massive growth in the big data makes difficult to analyse and retrieve the useful information from the set of available data's. Existing approaches cannot guarantee an efficient retrieval of data from the database. In the existing work stratified sampling is used to partition the tables in terms of stratic variables. However k means clustering algorithm cannot guarantees an efficient retrieval where the choosing centroid in the large volume of data would be difficult. And less knowledge about the stratic variable might leads to the less efficient partitioning of tables. This problem is overcome in the proposed methodology by introducing the FCM clustering instead of k means clustering which can cluster the large volume of data which are similar in nature. Stratification problem is overcome by introducing the post stratification approach which will leads to efficient selection of stratic variable. This methodology leads to an efficient retrieval process in terms of user query within less time and more accuracy.
