Abstract :
Issues concerning the transference of data from existing databases to other applications are discussed. The process of transferring data is called data migration, and it is divided into two processes: extracting data from existing systems in the form of an extracted file, and loading data from the extracted file into the new application. The new application usually requires data in different formats, and so transformation of data is generally needed. Moreover, the new application frequently requires data from more than one source database system, so integration of data is necessary in the migration process
