89 Bags And Counting

Bringing readers and travelers a fascinating but cautionary account of an airport's baggage-handling system, Steve Chart shares the many interesting and at times humorous investigations he undertook as a security consultant to the Airports Company South Africa. In 2007 Steve Chart was appointed with the task of assisting in the reduction of baggage pilferage at OR Tambo International Airport in South Africa. What Steve soon realized, however, was that in terms of security, the airport wasn't a vessel with a small leakage problem but a boat on the absolute verge of sinking. He discovered a criminal incursion within the South African travel industry, encountering countless cases of corruption, poor management, and no desire to take responsibility. This personal narrative of his investigations serves as a reminder to the public about protecting their luggage, themselves, and their fellow travelers.

Information Modeling and Relational Databases provides an introduction to ORM (Object Role Modeling)-and much more. In fact, it's the only book to go beyond introductory coverage and provide all of the in-depth instruction you need to transform knowledge from domain experts into a sound database design. Inside, ORM authority Terry Halpin blends conceptual information with practical instruction that will let you begin using ORM effectively as soon as possible. Supported by examples, exercises, and useful background information, his step-by-step approach teaches you to develop a natural-language-based ORM model and then, where needed, abstract ER and UML models from it. This book will quickly make you proficient in the modeling technique that is proving vital to the development of accurate and efficient databases that best meet real business objectives. * The most in-depth coverage of Object Role Modeling available anywhere-written by a pioneer in the development of ORM. * Provides additional coverage of Entity Relationship (ER) modeling and the Unified Modeling Language-all from an ORM perspective. * Intended for anyone with a stake in the accuracy and efficacy of databases: systems analysts, information modelers, database designers and administrators, instructors, managers, and programmers. * Explains and illustrates required concepts from mathematics and set theory. * Via a companion Web site, provides answers to exercises, appendices covering the history of computer generations, subtype matrices, and advanced SQL queries, and links to downloadable ORM tools.

The mathematical concepts and notational conventions we know of as Z were first proposed around 1981. Its origins were in line with the objectives of the PRG - to establish a mathematical basis for program ming concepts and to verify the work by case studies with industry. Hence among early Z users some were from academic circles, with interests in the mathematical basis of programming; others came from industry and were involved with pilot projects and case studies linked with the Programming Research Group. Four years ago we had the first Z User Meeting, a fairly modest affair with representatives more or less equally divided between academia and industry. At the first meeting there were, as in this meeting, a variety of technical papers, reports of work in progress and discussions. A number of people from industry came along, either because they had begun to use Z or were curious about the new direction. In the discussion sessions at the end of the meeting, there were calls from attendees for the establishment of a more stable base for the notation, including work on its documentation and standards. Many of these requests have now been satisfied and the notation is now being proposed for standards development.
