Using XML with Legacy Business Applications
Oracle Modernization Solutions: A practical guide to planning and implementing SOA Integration and Re-architecting to an Oracle platform
Product Description
In Detail
Much has been written about legacy modernization in the past few years. Most of the books, analysts’ reports, and white papers focus on why you should modernize and theorize at a high level regarding the different approaches and possible outcomes. This book provides a detailed guide to how to implement two well known mainframe modernization approaches–SOA Enablement and Re-architecture.
SOA Integration is a non-invasive approach and allows legacy components to be used as part of an SOA infrastructure quickly and without risk and is often the first step in the larger modernization process. Re-architecture focuses on reverse engineering legacy applications to preserve business knowledge then forward them to modern architectures that take advantage of open and extensible standards.
In this book you will learn how to quickly and easily expose a mainframe VSAM data store in an Oracle-based Java EE application. You will also learn how to leverage your mainframe application code to create a new Oracle/Java EE SOA-based application. The book is agnostic in terms of hardware and operating system as most of these have proven to be able to handle the reliability, scalability, and performance of a mainframe system.
After reading this book, you will feel much more comfortable that mainframe modernization is possible and can made less risky by following the recommendations and approaches used in the book.
What you will learn from this book?
- Gain an understanding of different approaches to modernization of legacy systems
- Determine your short and long term modernization strategies and know how to look for the right business and technology drivers in your organization
- Understand when and why you would choose the modernization options of SOA Integration and Re-architecture
- Architect an Oracle-based platform for you modernized legacy system
- Know the best approaches to take to transform your application from a rigid, monolithic system to an agile, adaptable application based on Oracle and SOA
- Quickly SOA-enable your legacy mainframe application using legacy SOA Integration
- Use the hands-on SOA Integration example that walks you through the entire development process as a starting point for your own pilot project
- Use the hands-on Re-architecture example that focuses on forward engineering business rules, presentation tier, and screen navigation from the legacy system into an Oracle platform as a starting point for your own pilot project
- Learn about Oracle’s modernization re-host solution: Oracle Tuxedo
- Dive into the future of legacy modernization based upon industry trends such as Extreme Transaction Processing (XTP), Grid computing, Cloud computing, etc.
Approach
This book combines case studies with practical examples of how to implement modernization techniques using Oracle (and partner) products to modernize to the Oracle Platform. The book also weighs the pros and cons of specific modernization use cases. Finally, we explore some of the emerging trends in technology and how they apply to legacy modernization.
Who this book is written for?
Legacy system architects, project managers, program managers, developers, database architects and decision makers who own mainframe and heterogeneous systems, and are tasked with modernization will all find this book useful.
The book assumes some knowledge of mainframes, J2EE, SOA, and Oracle technologies. The reader should have some background in programming and database design.

Product Description
Foreword by Ray Harishankar, IBM Fellow
“There are many books on the market on the topic of SOA and SOA’s business and technology value. This book focuses on one of the key technical values of SOA and does an excellent job of describing SOA-based application integration by clarifying the relationship and patterns of SOA with other integration technologies in a distributed computing environment.” Sandra Carter, IBM Vice President for SOA, BPM, and WebSphere Marketing
“Services Oriented Architectures present many challenges today in the integration of existing systems and new systems, along with many times, old legacy mainframe applications. This book successfully addresses many of the complexities we see in the integration of SOA and mainframe legacy applications, presenting options and approaches to integrate the applications with the rest of the enterprise. The author takes a clearly defined pattern-based approach discussing the advantages, tools and methods. Readers will benefit from the insights in this book whether they play the architect role or a developer role on a SOA project.” Sue Miller-Sylvia, IBM Fellow and Application Development Service Area Leader
SOA-Based Enterprise Integration: A Step-by-Step Guide to Services-based Application
SOA Approach to Integration: XML, Web services, ESB, and BPEL in real-world SOA projects
Product Description
XML, Web services, ESB, and BPEL in real-world SOA projects
- Service-Oriented Architectures and SOA approach to integration
- SOA architectural design and domain-specific models
- Common Integration Patterns and how they can be best solved using Web services, BPEL and Enterprise Service Bus (ESB)
- Concepts behind SOA standards, security, transactions, and how to efficiently work with XML
In Detail
Integration of applications within a business and between different businesses is becoming more and more important. The needs for up-to-date information that is accessible from almost everywhere and developing e-business solutions — particularly business to business — require that developers find solutions for integrating diverse, heterogeneous applications, developed in different architectures and programming languages and on different platforms. They have to do this quickly and cost effectively, but still preserve the architecture and deliver robust solutions that are maintainable over time.
Integration is a difficult task. This book focuses on the SOA approach to integration of existing (legacy) applications and newly developed solutions, using modern technologies, particularly web services, XML, ESB, and BPEL. The book shows how to define SOA for integration, what integration patterns to use, which technologies to use, and how to best integrate existing applications with modern e-business solutions. It also shows how to develop web services and BPEL processes, and how to process and manage XML documents from the JEE and .NET platforms. Finally, it also explains how to integrate both platforms using web services and ESBs.
What you will learn from this book?
- How to design and develop SOA for integration
- Integration architecture patterns, principles, and best practices, with focus on the process-centric SOA approach
- The role of XML, web services, and ESBs in SOA for integration
- The role of service composition and BPEL in integration
- J2EE and .NET integration
- Why and how to use web services and XML for integration
Approach
After explaining the challenges, levels, and strategies of integration the book explains SOA, web services, and the Enterprise Services Bus before covering processing XML and web services on the .Net and JEE platforms in more detail. Then it covers BEPL and demonstrates service composition into business processes with a realistic, although simple example BPEL process. Finally it shows how ESB provides a concrete infrastructure for SOA.
Who this book is written for?
This book is for architects and senior developers who are responsible for setting up SOA for integration for applications within the enterprise (intra-enterprise integration) and applications across enterprises (inter-enterprise integration or B2B).
