Complex Event Processing in Oracle
Database 11g.
Complex patterns of events as exceptions to normal
operations, representing threats and opportunities,
occur across application space and time. Businesses
need to identify these patterns to respond automatically
and immediately. Applications that can benefit from
Complex Event Processing (CEP) include: fraud, compliance,
risk mgnt., cross-selling, EPC/RFID, CRM, asset tracking,
and Semantic Web domain node communications.
Rules Manager, the CEP feature of Oracle Database
for application developers:
- Supports a variety of event sources
to add CEP to existing applications
- Orchestrates CEP of any complexity
for events in any order and time period
- Implements declarative, dynamic
event patterns in Oracle Database using Event-Condition-Action
(ECA) rules with indexing, powerful event relationships,
conditions on rich data types and efficient access
to multi-terabyte reference data.
- Achieves scaleability for large
numbers of patterns, fault-tolerance and efficient
rule evaluation by keeping incremental state of
pattern evaluations.
- Provides policies to control
event and rule evaluation behavior.
- Enables rules actions in Oracle
Database and / or applications

The Rules Manager Utility is available to download.
It makes it easy to create CEP applications
in Oracle Database. Define event structures,
rule class and ECA rules that describe complex
event patterns. (Click the thumbnail on the

Expression Filter is a feature of Oracle Database
that enables application developers to store,
index and evaluate conditional expressions as
another kind of data. Conditional expressions
are useful to describe interests in expected data.
