The Internet Inter-ORB Protocol (IIOP) is a communications mechanism that allows object request brokers (ORBs) to communicate with one another. IIOP is an integral part of the broader Common Object Request Broker Architecture (CORBA) standard that has been developed and widely promoted throughout industry by the Object Management Group. IIOP was designed to allow disparate software components to communicate with one another, and it ensures interoperability on top of the most popular communications protocol in use today -- TCP/IP. While IIOP is a specialized subset of the broader CORBA specification, its popularity is increasing steadily. In fact, IIOP support has become one of the standard checkbox items that software vendors are adding to their product descriptions. This book provides a broad perspective of IIOP, allowing any CORBA developer to gain an in-depth understanding of this foundational standard. In turn, an increased knowledge of IIOP allows systems developers to more easily build interoperable objects for the enterprise.

Please note this is a Short Discount publication. LANs have gone through stages. Early LANs connected asychronous terminals to minicomputers. With the advent of the IBM PC the focus on technology changed to that of PCs connected to some type of 'file server'. After a number of years, the battle over file servers turned into a battle of network operating systems. With the advent of the client server model, and high performance workstations, one direction the battle has been taking is to develop a high performance server engine. The general strategy in this arena is to attempt to remove bottlenecks in the processing of service requests to the various networks operating. Several consortiums of venture capitalists have poured amounts of money in the range of $20m into developing the ultimate high performance server. With Novell shipping thousands of copies of NetWare 386 per month, this lucrative market is about to undergo intense long term competition. This report describes the general approaches that can be used to develop a high performance server and several of the key products in the area including products from several start up ventures.

This IBM® Redbooks® publication describes IBM TXSeries® for Multiplatforms, which is the premier IBM distributed transaction processing software for business-critical applications. Before describing distributed transaction processing in general, we introduce the most recent version of TXSeries for Multiplatforms. We focus on the following areas: The technical value of TXSeries for Multiplatforms New features in TXSeries for Multiplatforms Core components of TXSeries Common TXSeries deployment scenarios Deployment, development, and administrative choices Technical considerations It also demonstrates enterprise integration with products, such as relational database management system (RDBMS), IBM WebSphere® MQ, and IBM WebSphere Application Server. In addition, it describes system customization, reviewing several features, such as capacity planning, backup and recovery, and high availability (HA). We describe troubleshooting in TXSeries. We also provide details about migration from version to version for TXSeries. A migration checklist is included. We demonstrate a sample application that we created, called BigBlueBank, its installation, and the server-side and client-side programs. Other topics in this book include application development and system administration considerations. This book describes distributed IBM Customer Information Control System (IBM CICS®) solutions, and how best to develop distributed CICS applications.

This handbook covers the vast field of business information systems, focusing particularly on developing information systems to capture and integrate information technology together with the people and their businesses.Part I of the book, “Health Care Information Systems”, focuses on providing global leadership for the optimal use of health care information technology (IT). It provides knowledge about the best use of information systems for the betterment of health care services. Part II, “Business Process Information Systems”, extends the previous theory in the area of process development by recognizing that improvements in intra-organizational business processes need to be complemented by corresponding improvements in inter-organizational processes. Part III deals with “Industrial Data and Management Systems” and captures the main challenges faced by the industry, such as the changes in the operations paradigm of manufacturing and service organizations. Finally, Part IV, “Evaluation of Business Information Systems”, discusses the empirical investigation into the adoption of systems development methodologies and the security pattern of the business systems along with the mathematical models.

Typically, analysis, development, and database teams work for different business units, and use different design notations. With UML and the Rational Unified Process (RUP), however, they can unify their efforts -- eliminating time-consuming, error-prone translations, and accelerating software to market. In this book, two data modeling specialists from Rational Software Corporation show exactly how to model data with UML and RUP, presenting proven processes and start-to-finish case studies. The book utilizes a running case study to bring together the entire process of data modeling with UML. Each chapter dissects a different stage of the data modeling process, from requirements through implementation. For each stage, the authors cover workflow and participants' roles, key concepts, proven approach, practical design techniques, and more. Along the way, the authors demonstrate how integrating data modeling into a unified software design process not only saves time and money, but gives all team members a far clearer understanding of the impact of potential changes. The book includes a detailed glossary, as well as appendices that present essential Use Case Models and descriptions. For all software team members: managers, team leaders, systems and data analysts, architects, developers, database designers, and others involved in building database applications for the enterprise.
