# Chapter 1. Introduction

# 1.1. What is Cascade Connect?

Cascade Connect is an application that links programs running in Windows (Microsoft Windows) with programs running on a data server (either a QNX 4, QNX 6, or Linux computer). The link uses TCP/IP over a standard network connection. It is fast, fault-tolerant and extremely easy to install and configure.

Cascade Connect is started from the Windows computer and it comprises two co-operating tasks, one (Cascade Connect) running on the Windows computer and the other (Connect Server) running on the data server. Unlike other approaches to cross-platform communication, Cascade Connect uses native message protocols in both Windows and the data server. The Cascade Connect program communicates with the Windows application using DDE messaging. The Connect Server program sends and receives messages using a send/receive/reply mechanism that is compatible with the data server's operating system.

Cascade Connect uses zero system resources when it is not running and uses no permanent administrators, TSRs, DLLs or VxDs at any time. There is no programming required, and a Cascade Connect Setup program assists in the configuration of the link.

## 1.1.1. The Cascade DataHub

The Cascade DataHub is a flat, non-relational database that actively distributes data over a network in real time. Residing on the data server network, it works with Cascade Connect to provide extremely fast and flexible data collection and distribution. The Cascade DataHub is often paired with Cascade Connect to provide a convenient interface on the data server and reduce network traffic. If for some reason you don't use the Cascade DataHub, you can still pass data directly to the Connect Server, but you will loose some Cascade Connect functionality.
