XPOR uses a simple system modelling approach to developing software. This means you can easily design and build your web based Applications - online systems that will work the same way your business does.
We've identified that we have some discrete "things" in our Off Site Visit system;
So we sketch these out - and join them up how they are in real life. Then tidy the sketch into a Visio (my preferred) drawing.
The System Model is the conceptual model that describes a system, which itself comprises, structure, behaviour, input data, and output data views. Well that's the technical definiton. In plain words, however, it is the representation of how things hang together in an organisation.
You can build this in XPOR in a couple of hours (allowing for tea and biscuits) using the System Modeller tool. If there is some aspect of the information required to make the Application work that is not available with this model - extend the model.
