The invention provides novel systems, methods and software for business activity monitoring. In one aspect of the invention, for example, events can be monitored and/or evaluated before the data is stored in a database. This can provide for real-time business activity monitoring and, in some cases, can prevent the database from becoming a bottleneck in the monitoring process. Merely by way of example, a business activity monitor process might be implemented in a middleware layer between an enterprise application and the database that is used to store data for the application.
