Generally, the RulePoint administrator configures RulePoint services to connect to your data sources. The data sources then feed events into your topics, against which you would write a rule. Topics, which are collection of these events, apply properties to the incoming events so that RulePoint can process the data appropriately. You can create properties for structured event sources (name=Chris, stock=INFA, temp=82, RSS news feeds, SQL databases) as well as unstructured event sources (web pages, documents, third party connectors). Define topic properties for incoming events so you can easily create rules for existing event sources as your business requirements change.
