Neuentwickelte Software ist heute oft schon zum Zeitpunkt Ihrer Einfuhrung veraltet. Einen Ausweg aus dieser Krise bietet der objektorientierte Ansatz: Anwendungen werden als Software-Objekte modelliert, die sowohl die Eigenschaften als auch das Verhalten von Objekten aus der realen Welt beschreiben. Solche Objekte sind gekapselt und verbergen die innere Komplexitat hinter einer offentlich bekannt gegebenen Schnittstelle. Dadurch konnen Objekte in den verschiedensten Programmpaketen verwendet werden, ohne dass die interne Realisierung bekannt sein muss. Die Verbindung objektorientiert modellierter Anwendungen mit einer Datenbank stellt besondere Anforderungen an DBMS und Entwicklungsumgebung, will man die ublichen Performance- und Semantikverluste vermeiden. Dieses Buch behandelt ausfuhrlich das Objektmodell der postrelationalen Datenbank Cache. Zudem wird der Leser Schritt fur Schritt bei der Entwicklung einer ersten postrelationalen Applikation begleitet. Die komplette Software hierzu einschliesslich einer Single-User-Version von Cache 5 ist auf der beigefugten CD-ROM enthalten. Die vorliegende zweite, uberarbeitete und erweiterte Auflage berucksichtigt die zahlreichen Neuerungen der Cache-Version 5. Die Beschreibungen der Java- und ActiveX-Anbindung und des SQL-Managers von Cache wurden grundlegend uberarbeitet und erweitert. Neu hinzugekommen sind eine ausfuhrliche Beschreibung des neuen Cache Studio mit seinen umfassenden Verbesserungen fur die Anwendungsentwicklung sowie Kapitel uber die Web-Entwicklung mit den Cache Server Pages (CSP), den Datenaustausch mit XML und die Entwicklung von SOAP-basierten WebServices."

Die Versorgung des Managements mit validen und aktuellen Informationen zur Wahrnehmung der Fuhrungs-, Steuerungs- und Kontrollaufgaben ist zu einer der wichtigsten Herausforderungen fur die Wirtschaftsinformatik geworden. Die Forderung nach integrierten Informations- und Kommunikationssystemen, welche aus unternehmensinternen und unternehmensexternen Datenquellen entsch- dungsrelevante Informationen mit einem hohen Mass an Automatisierung zus- mentragen und aufbereiten, begleitet die IT-Abteilungen seit vielen Jahren. Unter wechselnden Schlagworten wurden Konzepte zur Informationsversorgung des Managements propagiert, deren Einsatztauglichkeit aber haufig hinter den Erw- tungen zuruckblieb. Dennoch haben sich in den 90er Jahren in fast allen Unt- nehmungen Data-Warehouse-Losungen durchsetzen konnen, da diese nachwe- lich zu einer erhohten Qualitat und Aktualitat der Informationsbereitstellung fur Fach- und Fuhrungskrafte beitragen. Unter dem Begriff Business Intelligence" werden derzeit dialogfahige Informationssysteme mit hohem Verfugungsgrad, intuitiver Nutzbarkeit und analytischer Funktionsvielfalt verbreitet, die auf dem bereinigten Datenbestand eines derartigen Data Warehouse aufsetzen. Der SAP AG gelang es, nach spatem Entwicklungsstart in diesem Marktsegment mit dem Produkt SAP Business Information Warehouse (SAP BW )" einen fuhrenden Platz einzunehmen. Als Plattform fur die Sammlung von betriebswi- schaftlichen Grunddaten ist das SAP BW ein wesentlicher Bestandteil der Anwendungsarchitektur im Gesamtkonzept der SAP-Produkte geworden. Samt- che Systemkomponenten, welche Planungs-, Steuerungs- und Berichtsaufgaben unterstutzen, beziehen jetzt und zukunftig ihre Daten aus dem SAP BW . Dies gilt sowohl fur das Produkt SAP Strategic Enterprise Management (SAP SEM )" als auch fur die Softwarekomponente SAP Advanced Planner and Optimizer (SAP APO ).""

Magnetic random-access memory (MRAM) is poised to replace traditional computer memory based on complementary metal-oxide semiconductors (CMOS). MRAM will surpass all other types of memory devices in terms of nonvolatility, low energy dissipation, fast switching speed, radiation hardness, and durability. Although toggle-MRAM is currently a commercial product, it is clear that future developments in MRAM will be based on spin-transfer torque, which makes use of electrons spin angular momentum instead of their charge. MRAM will require an amalgamation of magnetics and microelectronics technologies. However, researchers and developers in magnetics and in microelectronics attend different technical conferences, publish in different journals, use different tools, and have different backgrounds in condensed-matter physics, electrical engineering, and materials science. This book is an introduction to MRAM for microelectronics engineers written by specialists in magnetic materials and devices. It presents the basic phenomena involved in MRAM, the materials and film stacks being used, the basic principles of the various types of MRAM (toggle and spin-transfer torque; magnetized in-plane or perpendicular-to-plane), the back-end magnetic technology, and recent developments toward logic-in-memory architectures. It helps bridge the cultural gap between the microelectronics and magnetics communities.
