A framework for evaluating skyline query over uncertain autonomous databases

The perception of skyline query is to find a set of objects that is much preferred in all dimensions. While this theory is easily applicable on certain and complete database, however, when it comes to data integration of databases where each has different representation of data in a same dimension,...

description The perception of skyline query is to find a set of objects that is much preferred in all dimensions.
