Abstract: To solve the problem that scalablility of business process management was limited by traditional process data management in request-intensive critical applications, a feature-based scalable management mechanism was proposed. This mechanism fully considered various data feature in business process management, and utilized advantages of both relational database and distributed key-value storage system to manage corresponding process data. The overall performance and scalability of the entire system were improved, and moreover, an abstract process data access layer was designed to shield the differences of infrastructure data models for process engine. Effectiveness of the proposed mechanism was verified by experiment.

Key words: business process management, features, scalability, process data management, relational database, distributed key-value storage system
