Analyzing hard-to-obtain data from two separate databases

Assignment Help Database Management System
Reference no: EM1351685

Q1) You are interested in analyzing some hard-to-obtain data from two separate databases. Each database contains n numerical values--so there are 2n values total--and you may assume that no two values are the same. You'd like to determine the median of this set of 2n values, which we will define here to be the nth smallest value.
However, the only way you can access these values is through queries to the databases. Ina single query, you can specify a value k to one of the two databases, and the chosen database will return the/(m smallest value that it contains. Since queries are expensive, you would like to compute the median using as few queries as possible. Give an algorithm that finds the median value using at most O(log n) queries.
