- Migration_testing abstract "http://en.wikipedia.org/wiki/Data_migrationDatabase migration testing is needed when data is moved from one database(s) to another. The first database is called the legacy or source database and the latter is called the target or destination database. Database migration may be done manually, but it is more common to use an automated ETL (Extract-Transform-Load) process to move the data. In addition to mapping the old data structure to the new data structure, the ETL tool may incorporate certain business rules to increase the quality of data moved to the target database as follows: (i) All the live (not expired) entities (e.g. customer records and order records) are loaded into the target database with each entity being loaded only once; (ii)Every attribute (present in the source database) of every entity (present in the source database) is loaded into the target database; (iii) All data related to a particular entity is loaded in each relevant table in the target database; (iv) Each required business rule is implemented correctly in the ETL tool; (v)The data migration process performs reasonably fast and without any major bottleneck.Database migration testing may encounter problems when:I. The data in the source database(s) changes during the test;II. Some of the source data is corrupt;III. The mappings between the tables/ fields of the source databases(s) and target database are changed by the database development/ migration team;IV. A part of the data from the source database is rejected by the target database;V. Data migration takes too long because the database migration process is too slow or the source data file is too large.".
