Access to Legacy Applications and Data

Why Replication?

Legacy database replication is a set of conversion processes that copies, reformats, and migrates database tables for use in relational databases running on Windows 2000 Server. Using data replicated from a legacy database, developers and systems engineers can:

Integrate the legacy data with data from the Windows 2000 Server side. If the data is replicated for storage in a Windows 2000 Server–side database, IIS 5.0 connects Internet or intranet clients to dynamically created Web pages. The data is then retrieved through OLE DB provider or Open Database Connectivity (ODBC).
Readily subject the data to new business logic. For new processes involving the database, developing in Windows is less costly than developing in legacy systems.
Manage the data efficiently. Windows 2000 Server with IIS 5.0 provides a common set of system management tools, database management tools, Web application servers, and transaction services.
If the application requires it, rereplicate the data from SQL back to the legacy database.
