Effective Technique for Missing Value Evaluation in Database
Due to the fact that existing database systems are increasingly more difficult to use, improving the quality and usability of database systems has gained tremendous momentum over the last few years. In particular, the feature of explaining why some expected answers are missing in the result of a query has received more attention. At the same time, handling those missing answers has become more important. In this paper Missing Value Restoration Algorithm is used for handling missing values. The main goals of this research paper are: (i) surveying the problem of answering the why and why-not questions in databases and (ii) handling missing values in database. This research paper contributes towards improving the usability of traditional database systems.
