Figure 21. BAM architecture
The BAM server controls operation of the event pipe and resulting transfer of data from the audit trail
database table to the BAM database integration table. Each row of the integration table contains data
about one process instance (activities, performers, queues, and business data). The format engine
extracts information from the integration table and maps it into different execution tables for the
different types of process instance data (activities, performers, queues, and business data).
The aggregation engine aggregates process instance data from the execution tables into groupings,
for which one or more arithmetic functions apply, and stores the groupings in an aggregation table.
The alert engine scans rows in the execution and aggregation databases and evaluates them for alert
conditions defined in Process Reporting Services (PRS). The alert engine adds process instances
(rows), that satisfy the alert condition, to the BAM database alert instance table.
