Networks

Networks and Client/Server scenarios influence the possibilities for data sharing. The performance of data transaction is different for both types of network. As a result, the type of network has a great influence on the usability of most of the data sharing methods. Secondly, some of the data sharing methods may or may not be possible depending on the client/server scenario that was chosen.

In each scenario, a distinction can be made between the application (including bshell), the database driver and the database. These three can be connected by means of a network. Two main types can be distinguished: Local Area Network (LAN) and Wide Area Network (WAN).

An LAN is a network of data lines in a physical location. The speed of data transactions is extremely good. A WAN is made up in most cases of rented cables that run over long distances. The capacity and the length of the cable restrict the volume and speed of data transfer. A WAN is generally more sensitive to breakdowns, for example, due to physical damage.

In general, if a WAN network is used, Infor does not recommend that you perform synchronous transaction processing. In regard to asynchronous replication of data, you can use both types of network.
