Refactoring workbench with migration support

A computer-implemented system comprising:

• memory storing application programming interface (API) information;
• and
• a server performing operations comprising:
• receiving a user input specifying current databases used for an old software product version, the user input comprising a definition of a target persistency layout comprising databases assigned for storing a new software product version undergoing a development process, the old software product version comprising an application code defining interactions with data stored in one or more database tables and the new software product version comprising an adjustment to the application code associated with a migration of the data to one or more target database tables;
• reading sizes of the one or more database tables from a catalog of a database;
• generating a migration assessment of the new software product version based on the sizes of the one or more database tables;
• executing a migration test of the one or more database tables using the migration assessment to generate migration test results;
• and
• providing an updated adjustment to the one or more database tables and a rearchitecture of the new software product version, during the development process, based on the migration test results.

A non-transitory, computer-readable media encoded with a computer program, the computer program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving a user input specifying current databases used for an old software product version, the user input comprising a definition of a target persistency layout comprising databases assigned for storing a new software product version undergoing a development process, the old software product version comprising an application code defining interactions with data stored in one or more database tables and the new software product version comprising an adjustment to the application code associated with a migration of the data to one or more target database tables;
• reading sizes of the one or more database tables from a catalog of a database;
• generating a migration assessment of the new software product version based on the sizes of the one or more database tables;
• executing a migration test of the one or more database tables using the migration assessment to generate migration test results;
• and
• providing an updated adjustment to the one or more database tables and a rearchitecture of the new software product version, during the development process, based on the migration test results.
