Database Migration Improved
Based on compatibility and advanced connectivity technologies developed by ANTs, the ANTs Compatibility Server is a database virtualization middleware solution that allows application code — queries, stored procedures, and functions — from legacy databases to run natively and transparently against the new target database with minimal to no application rewriting and recompiling. The legacy application operates as if it were still communicating with the original legacy database, while the new target database operates as if it were communicating with a native application.
Eliminate Application Rewrites
The ACS enables improved database migration process with faster to consolidation benefits. Dramatically lower your database related operational costs by elimiating other database license and support fees. Improve your security and compliance with fewer databases.
The Compatibility Server is designed to significantly reduce migration complexity, effort, and cost by:
Automating the processes that current migration tools cannot, saving time and effort
Reducing hand-coding and manual error checking. Many man-months or even years can be required for this, and hand-coding can introduce errors and uncertainty in the process, requiring a significant QA effort to ensure correctness
Avoiding costly application rewrites and recompiles by providing continued use of native access libraries (JDBC, ODBC, Oracle OCI and Sybase DB-LIB or CT-LIB)
Automating the translation of all the database objects
In addition to automating the migration of tables, views, synonyms, constraints and triggers, stored procedures and other server-side application code can be migrated easily and without the difficulty of maintaining computer-generated code.
