I. Introduction
Data centric applications based on relational model fetch data using SQL queries. The criteria for fetching data may be simple or complex in nature. Some of the complex queries may involve multi-criteria decision makings, where the criteria are inversely proportional to each other. Optimization on these types of multi-criteria decision makings cannot be optimized directly using SQL. One of the solutions of this type of problem is to identify the best point of one dimension (corresponds to attribute) and rank all the other points according to that.
