Nature of the client and application

It is equally important to understand the role of clients that connect to the DB2 Servers. If a client consists of solely JDBC or ODBC applications, then full deployment of a DB2 product might not be necessary. To determine the required features of the product, also consider whether the client has to perform database administration or DB2 application development.
