In a metadata-based strategy, the data integration administrator uses some features of source. One of the most important features in metadata-based strategy is source accuracy, which is concerned with the correctness with which real world data to what is in data source. However, it is difficult to calculate accuracy for all data sources by comparing data about objects with what is in real world, so that we propose a method to select one source as a reference and propose a new way to approximate sources accuracy using reference source accuracy Issued also as CD Data Integration Metadata Source Accuracy Ali Elbastawissy , Supervisor Osman Hegazy , Supervisor http://172.23.153.220/th.pdf Aml Cataloger Nazla Revisor ddc TH 53604 53604 ddc 0 CUCL cl210 2024-02-11 Cai01.20.04.M.Sc.2015.Al.T 01010110066892000 2023-09-22 00:00:00 TH ddc 0 CUCL cl2u8 2024-02-11 Cai01.20.04.M.Sc.2015.Al.T 01020110066892000 2023-09-22 00:00:00 66892.CD CD
