ACTIVE DECISION SUPPORT

Up till now, decision support has been a passive activity. The data warehouses that have been developed so far are of the passive variety. This means that they tend to just sit and wait for someone or some application to ask them a question, and they react and provide an answer. The idea of an active decision support system (DSS) is one that knows what it is that we are interested in. It is constantly searching for new information of changes to situations and when it finds something that may be of interest to us, it lets us know.

This is not the same thing as alerts. Alerts have been around for a long time. The obvious application for alerts is where a stock price is monitored . When it rises by a certain amount or falls by a certain amount, then the alert system somehow informs us of the change and we can react accordingly . Active DSS is far more than this. An active DSS system is one that actively looks for information on our behalf , once it knows what we are interested in. This can vary from being quite trivial, such as wanting to be kept informed about the responses obtained from a particular campaign, to very complex, such as the political and economic situation in a particular region of the world where we have a manufacturing plant. Notice that the latter is a fairly general request to be kept informed. The sources of information might be news broadcasts, newspapers, and journals. This type of information has two properties that, hitherto, we haven't really considered : external data and unstructured data.
