Only Microsoft Access tables can be migrated using the Upsizing Wizard. Some Microsoft Access applications use two databases; the tables are contained in one database (the back end) and queries, forms, reports, macros and modules in the other (the front end). The tables from the back end are attached to the front end. Since the Upsizing Wizard ignores attached tables, you must use the back-end database.
The selection of the Microsoft Access tables that you wish to export to ADABAS has a decisive influence on the performance of your application.
A good Microsoft Access client/server application consists of a mixture of local tables and tables in the server database. As a general rule, tables that are seldom modified should be kept in the local database and tables that are often modified or are accessed by a large number of users should be exported.
