The article discusses the development of the complex event processing (CEP) engines. CEP engines were developed from service-oriented architectures (SOA) and enterprise message buses (ESB) to offer real-time analysis on an enterprise scale. CEP engines uses a language based on SQL. However, SQL architecture is quite different from relational database and SOA and ESB were programmed using XML. Due to this, an XML datatype is required to the CEP engine and language. XML shredding is not recommended because it creates programming complexity and diminish performance. Implementation of CEP to SOA and/or XML-based messaging environment is suggested.
