The increasing popularity of Client/Server computing has created a huge demand for programmers versed in IBM's Customer Information Control System (CICS), and smart programmers everywhere are scrambling to get trained in it. This book gets programmers and developers with no previous online experience up and running in no time.
This comprehensive, authoritative guide to CICS/ESA Version 3 by IBM's CICS architecture and internals experts helps systems and applications programmers solve many of the problems they encounter while using CICS/ESA. Guidelines and methodologies as well as troubleshooting techniques offer the reader the opportunity for quick resolution of a wide variety of CICS problems.
This book describes how an automated patient medical record could be built that could evolve into a universal patient record. Such a universal patient record would change medical care from a focus on short-term care to one oriented to long-term, preventive-care. It would remove patient care from being the province of the single physician to that of the responsibility of many different healthcare providers, possibly located anywhere in the world.
The Architecture of Computer Hardware, Systems Software and Networking is designed help students majoring in information technology (IT) and information systems (IS) understand the structure and operation of computers and computer-based devices. Requiring only basic computer skills, this accessible textbook introduces the basic principles of system architecture and explores current technological practices and trends using clear, easy-to-understand language. Throughout the text, numerous relatable examples, subject-specific illustrations, and in-depth case studies reinforce key learning points and show students how important concepts are applied in the real world. This fully-updated sixth edition features a wealth of new and revised content that reflects today’s technological landscape. Organized into five parts, the book first explains the role of the computer in information systems and provides an overview of its components. Subsequent sections discuss the representation of data in the computer, hardware architecture and operational concepts, the basics of computer networking, system software and operating systems, and various interconnected systems and components. Students are introduced to the material using ideas already familiar to them, allowing them to gradually build upon what they have learned without being overwhelmed and develop a deeper knowledge of computer architecture.
The only CICS book that covers all IBM platforms, including the newly announced CICS/6000 and CICS for OS/400. Crownhart explains how to exploit CICS facilities, make informed and effective choices when designing "real-world" applications, and utilize client/server functionality within a CICS application. He also covers distributed and cooperative processing.
This newly revised reference presents fundamental computer hardware, systems software, and data concepts. It provides a careful, in depth, non-engineering introduction to the inner workings of modern computer systems. The book also features the latest advances in operating system design and computer interconnection.
Most computer architecture books are just too technical and complex. Focusing on specific technology, they often by-pass the basics and are outdated as quickly as technology advances. Now you can give your students a gentle introduction to computer architecture and systems software that will provide the appropriate amount of technical detail they need to make successful decisions in their future careers. This text covers the basics in an accessible, easy to understand way. Organized in a form that parallels an actual computer system, entire sections are devoted to principles of data, hardware, and software, to emphasize the importance of computer structure. Assuming only basic knowledge, these sections build up to an in-depth understanding of each topic and how they interrelate to make up a computer system.
