Products for accessing legacy and host data

With the following DB2 products, you can extend your enterprise system to 

access the legacy system:

DB2 Connect  Personal Edition

The DB2 Connect Personal Edition provides the application programming 

interface (API) drivers and connectivity infrastructure to enable direct 

connectivity from desktop applications to zSeries and iSeries database 

servers. This product is specifically designed and is licensed for enabling 

two tier, client server applications running on individual workstations, and as 

such is not appropriate for use on servers.

DB2 Connect Enterprise Edition

The DB2 Connect Enterprise Edition addresses the needs of organizations 

that require robust connectivity from a variety of desktop systems to zSeries 

and iSeries database servers. DB2 client software is deployed on desktop 

systems, and provides drivers that connect client server applications running 

on these desktop systems to a DB2 Connect server (gateway) that accesses 

host data. The licensing model for this product is user based.

DB2 Connect Application Server Edition

The DB2 Connect Application Server Edition product is identical to the DB2 

Connect Enterprise Server in its technology. However, its licensing terms and 

conditions are meant to address specific needs of multi tier, client server 

applications, as well as applications that utilize Web technologies. DB2 

Connect Application Server Edition license charges are based on the size and 

number of processors available to the application servers where the 

application is running.

The DB2 Connect Unlimited Edition product is ideal for organizations with 

extensive usage of DB2 Connect, especially where multiple applications are
