Abstract

Data migration process is usually required when there is a change in system, format or storage type. Nowadays, we are familiar with some technique and tools to perform data migration, for example CSV file, ODBC, SQLDump etc.Unfortunately, not all of this technique are applicable when it comes to migrating data between two different DBMS. This research give an overview about one particular data migration technique that is applicable for cross DBMS data migration. This technique utilizes metadata that exist in each DBMS. The data migration process described here consist of three stages, namely capture, convert and construct. A prototype is developed to test the proposed data migration technique. Using HR schema, a cross DBMS data migration test between Oracle and MySQL is conducted. Using this technique, full schema data migration requires an average time of 20,43 seconds to migrate data from Oracle to MySQL or an average time of 12,96 seconds for opposite scenario. As for patial data migration, an average time of 5,59 seconds is required to migrate data from Oracle to MySQL or an average time of 2,19 seconds for opposite scenario.
