Book Description

The increasing adoption of Business Process Management (BPM) has inspired pioneering software architects and developers to effectively leverage BPM-based software and process-centric architecture (PCA) to create software systems that enable essential business processes. Reflecting this emerging trend and evolving field, Process-Centric Architecture for Enterprise Software Systems provides a complete and accessible introduction explaining this architecture.

The text presents, in detail, the analysis and design principles used in process-centric architecture. Illustrative examples demonstrate how to architect and design enterprise systems based on the business processes central to your organization. It covers the architectural aspects of business process management, the evolution of IT systems in enterprises, the importance of a business process focus, the role of workflows, business rules, enterprise application integration, and business process modeling languages such as WS-BPEL and BPML. It also investigates:

  • Fundamental concepts of process-centric architecture style
  • The PCA approach to architecting enterprise IT systems
  • Business process driven applications and integration
  • Two case studies that illustrate how to architect and design enterprise applications based on PCA
  • SOA in the context of process-centric architecture
  • Standards, technologies, and infrastructure behind PCA

Explaining how to architect enterprise systems using a BPMS technology platform, J2EE components, and Web services, this forward-looking book will empower you to create systems centered on business processes and make today’s enterprise processes successful and agile.

He has around 14 years of work experience in the Information Technology (IT) industry as a researcher, educator, architect, and programmer. Before joining Infosys in 2001, he worked as an Advisory Systems Analyst with APL (American President Lines Ltd.), Oakland, California, U.S.A. Parameswaran has also worked as a software engineer with Case Consult (I) Pvt. Ltd., Thiruvananthapuram, India. He holds a Bachelor of Technology (B.Tech) degree in Computer Science and Engineering from the University of Calicut (in 1995). His work experience in the IT industry involved research, programming, architecture, and design.

At Infosys, Parameswaran has been doing research work in the area of Process-centric Architecture, Business Process Management (BPM) , Software architecture, and new computing models/paradigms. He has also been teaching architecture and high-end technology courses at Infosys. He was the lead architect for the home-grown Business Process Management System (BPMS) from Infosys and was also actively involved in its design and development. Parameswaran has architected, designed, programmed and supported a number of IT systems over his career as a computer software professional.

Parameswaran is an active researcher. He has published papers at international conferences and other forums. He has worked on joint research works with Microsoft Research India and Researchers from Universities such as Copenhagen University and University of Melbourne in the areas of BPM and Agent-oriented software engineering.

Parameswaran has designed, developed and supported IT systems involving various technologies, at APL. He programmed system tools to automate operations. He also led a team in software development and support projects at APL. Parameswaran programmed system tools based on REXX to automate conversion of programs from one programming environment to another, at Case Consult.

Parameswaran's areas of research interest include software architecture, process-centric architecture, new computing models, intelligent software agents and intelligent systems.
