This book was released on 2004-12-20 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diese Arbeit zeigt einen fur die Praxis gangbaren Weg zur Umsetzung zeitbezogener Daten in betrieblichen Informationssystemen auf. Das vorgestellte Modell bietet dafur einen strukturierten Ansatz, mit dem es moglich ist ohne Modifikation des DBMS-Kerns und ohne eine Zwischenschicht (z.B.: Pre-Compiler), den temporalen Aspekt in gangigen kommerziellen DBMS angemessen zu berucksichtigen. Das vorgestellte Modell erweist sich flexibel genug um auch analog auf den objektrelationalen Bereich angewendet werden zu konnen.

Download or read book SQL and Relational Theory written by C. Date and published by "O'Reilly Media, Inc.". This book was released on 2011-12-16 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put the theory into practice. In this insightful book, author C.J. Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it directly to your use of SQL. This second edition includes new material on recursive queries, “missing information” without nulls, new update operators, and topics such as aggregate operators, grouping and ungrouping, and view updating. If you have a modest-to-advanced background in SQL, you’ll learn how to deal with a host of common SQL dilemmas. Why is proper column naming so important? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Is it possible to write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports “quantified comparisons,” but they’re better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don’t support them properly. What can you do to resolve this situation? Database theory and practice have evolved since the relational model was developed more than 40 years ago. SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of SQL available. C.J. Date has a stature that is unique within the database industry. A prolific writer well known for the bestselling textbook An Introduction to Database Systems (Addison-Wesley), he has an exceptionally clear style when writing about complex principles and theory.

Download or read book Business in the Information Age written by Hubert Österle and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The industrial society is fast becoming an information society. As a result, many companies are experiencing serious difficulties in developing the new internal structures required. The increasing use of information technology has a profound effect on markets, products, and processes, as well as the management of and co-operation between companies. Recognising the possibilities and grasping the emerging potential is an important challenge for todays management, if the organisations and systems are to develop over the next twenty years. Business in the Information Age offers models and techniques for transforming company structures to help face this challenge. Viewing the business process as a new model to describe the organisation forms the link between company strategy and information systems. The book points out advantages accessible through IT, together with ways of integrating this knowledge in effective and efficient processes.

Available in PDF, EPUB and Kindle. Book excerpt: Before use, standard ERP systems such as SAP R/3 need to be customized to meet the concrete requirements of the individual enterprise. This book provides an overview of the process models, methods, and tools offered by SAP and its partners to support this complex and time-consuming process. It begins by characterizing the foundations of the latest ERP systems from both a conceptual and technical viewpoint, whereby the most important components and functions of SAP R/3 are described. The main part of the book then goes on to present the current methods and tools for the R/3 implementation based on newer process models (roadmaps).

Download or read book Towards User Centric Transport in Europe written by Beate Müller and published by Springer. This book was released on 2018-09-18 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to build a sustainable transport system for people and goods that meets the needs of all users, a truly integrated and seamless approach is needed, and the full potential of transformative technologies has to be exploited. This can only be achieved if user-centeredness, cross-modality and technology transfer become the paradigm of shaping future transport. Mobility4EU is a project funded by the European Commission that focusses on these topics and is working on delivering an action plan towards a user-centric and cross-modal European transport system in 2030. The authors of this contributed volume are dedicated scholars and practitioners connected to Mobility4EU either as partners or external contributors. Their contributions focus on understanding user needs and report on technologies and approaches that support the tailoring of a user-centered cross-modal transport system for passengers and freight on long distances and in the urban context.

Available in PDF, EPUB and Kindle. Book excerpt: Fur die meisten Wissenschaftler hei?t es: "Schreib' oder stirb!", aber nur die wenigsten wurden sich deshalb als passionierte oder gar brilliante Schreibkunstler bezeichnen. Um all jenen zur Hilfe zu kommen, die beim Abfassen wissenschaftlicher Texte auch auf den Schreibstil achten mochten, haben sich drei erfahrene Vielschreiber zusammengetan und diesen einzigartigen Leitfaden uber das Verfassen wissenschaftlicher Texte erstellt. Das Schwergewicht liegt dabei auf der richtigen Schreibtechnik, der Verwendung formaler Standards und vor allem einer klaren und unmissverstandlichen Darstellung wissenschaftlicher Sachverhalte. Diese lang erwartete neue Auflage eines Klassikers wurde von den Autoren vollstandig uberarbeitet, um den zum Teil dramatischen Veranderungen in der Form wissenschaftlicher Kommunikation des letzten Jahrzehnts gerecht zu werden. Durch seinen umfangreichen Anhang und ausfuhrlichen Index ist dieses Buch daruber hinaus ein unverzichtbares Nachschlagewerk, das jeder Verfasser wissenschaftlicher Texte, egal ob angehender Student oder etablierter Wissenschaftler, immer zur Hand haben sollte. "Ein Schatz an Informationen in einem einzigen Buch von handhabbarem Ausma?en. Studenten, die ein Experiment protokollieren, sowie Ihre Lehrer, die eine Veroffentlichung oder Vorlesung vorbereiten, werden in diesem Buch einen standigen Begleiter finden."
