General characteristics of use

Data Express for z/OS can be used in either Standard or Client/Server mode, whereas Data Express for Distributed Systems can only be used in Standard mode:

Data Express can be used in either Standard or Client/Server mode:

• Standard - Supports direct access to the data resident on RDBMS from your PC.
• Client/Server - Supports access to the data resident on RDBMS through the Data Express kbde-Server: a product based on a three-tier architecture where the second tier handles data transfer optimization. Client/Server mode lets you access data over the Internet with the lowest amount of administration necessary and the best utilization of network capacity.
  Note: Client/Server mode can use the same functions as Standard mode without you having to install additional software on your PC, such as the DB2 client or the Borland Database Engine (BDE).
