Exploring Workflow Enactments Through Querying Execution Logs
In this talk, we focus on analysis of business workflow executions (enactments) through *explorations* of business data in the form of ad hoc queries. The traditional ETL-data warehouse-OLAP approach tackles essentially a similar problem. However the types of data to be queried about and explored are limited to the data extracted by hard-coded ETL tools and stored into the data warehouse. Any changes (such as new data, new tasks, etc.) would demand at least modifications of ETL tools so that analysis remains accurate. In contrast to the traditional approach, we develop a new framework for business analytics based on workflow logs with support for ad hoc queries directly on logs. Using a simplified logical model for workflow logs, query languages are developed to formulate query conditions on task executions
as well as data manipulated by tasks. We also discuss further technical challenges.
Jianwen Su is Professor of Computer Science at the University of California, Santa Barbara. He received both B.S. & M.S. degrees in computer science from Fudan University and his Ph.D. degree in computer science from the University of Southern California. He held visiting positions at INRIA and Bell Labs. He has published over 100 journal and conference papers concerning query languages, data models, scientific databases, formal verification, web services, and business process management. His current work focuses on modeling and analysis of business processes concerning compositions and management. His work on data with nested structures, web services, and data-centric workflows is widely known and cited. Dr. Su was a recipient of 2007 & 2008 IBM Faculty Awards. He was a keynote/invited speaker for several workshops/conferences in web services. He served/is serving on program committees of many conferences in databases (e.g., PODS, ICDT, VLDB, ICDE, etc.) and service oriented computing (e.g., ICSOC, BPM, CooPIS, etc.). He was the general chair of ACM SIGMOD 2001 conference, the PC chair of ACM PODS 2009 conference, a program co-chair of WS-FM 2009, MDM 2007, ICWS 2005, and WAIM 2002, and a general co-chair of ICSOC 2013. He served on the Executive Committees of ACM SIGMOD (2003 to 2007) and PODS (2008-2011), is/was on the editorial board of International Journal of Cooperative Information Systems (IJCIS, 2015-present), International Journal of Foundations of Computer Science (IJFCS, 1999-2004), and Journal of Computer Science and Technology (JCST, 2005-2011). Professor Su taught three Dagon Star courses (Fudan Univ, 2004; Donghua Univ, 2007; BUPT, 2012).
