EMO:Connecting to a Database Server

WARNING: Connecting to a local or networked database server is complex and can be time-consuming. If no people in your company have previous experience of configuring EMarketOffer it is strongly recommended that you consult your company's technical support and also the Energy Link helpdesk for advice on the best approach.

Terminology

EMarketOffer's data design consists of 'things' included in the model, and their characteristics'. In this manual the 'things' are called Entities and their characteristics are called Traits. Traits may be static or dynamic.

For example the Circuit Entity can have the static Traits of Start Node and End Node, and the dynamic Traits of Powerflow and Loss by Trading Period.
