The abstraction gap between high-frequency IoT data and high-level business process logic creates a significant bottleneck for modern enterprises. Current architectures typically rely on separate middleware for event preprocessing, which introduces significant latency due to network hops and data serialization, and increases architectural complexity, creating multiple points of failure that hinder responsive operations. This paper introduces a synergistic engine paradigm that resolves this gap by leveraging a single complex event processing engine for both event abstraction and the direct execution of declarative MP-Declare models. Through a multi-level abstraction framework, process constraints are translated into executable queries, as demonstrated by a proof-of-concept. This unified approach provides a simplified architectural foundation for building highly responsive, event-driven applications that adapt intelligently to real-time conditions, as demonstrated by a proof-of-concept and a quantitative evaluation showing sub-millisecond latency at up to 10,000 events per second.
