| 20100094838 | Compatibility Server for Database Rehosting - A system and method describing a compatibility server for rehosting database applications written for a specific vendor's database on the database of a second vendor, without the need of rewriting the application to take into account differences in the application programming interfaces between the first vendor's database and the second vendor's database. Requests for access to the database are translated from one format to another at execution time. The server is also capable of translating error messages, data types and data formatting from the format used by the second database to that expected when making requests to the first database. Stored procedures defined in the first database are migrated to the second database as text blocks, and are translated at execution time into a high level programming language, compiled and executed against the second database. All information necessary for the mapping of schema, data, data types, error and status messages and data formatting, as well as information necessary to execute stored procedures, is stored in a plurality of metadata tables in the second database, which are created during a migration phase prior to executing the application. | 04-15-2010 |
