Now in its third edition, this best-selling book continues to bring you some of the best thinking on how to apply Oracle Database to produce scalable applications that perform well and deliver correct results. Tom Kyte and Darl Kuhn share a simple philosophy: "you can treat Oracle as a black box and just stick data into it, or you can understand how it works and exploit it as a powerful computing environment." If you choose the latter, then you’ll find that there are few information management problems that you cannot solve quickly and elegantly. This fully revised third edition covers the developments up to Oracle Database 12c. Significant new content is included surrounding Oracle's new cloud feature set, and especially the use of pluggable databases. Each feature is taught in a proof-by-example manner, not only discussing what it is, but also how it works, how to implement software using it, and the common pitfalls associated with it. Don’t treat Oracle Database as a black-box. Get this book. Get under the hood. Turbo-charge your career. Revised to cover Oracle Database 12c Proof-by-example approach: Let the evidence be your guide Dives deeply into Oracle Database’s most powerful features
Oracle Database Transactions and Locking Revealed provides much-needed information for building scalable, high-concurrency applications and deploy them against the Oracle Database. Read this short, 150-page book that is adapted from Expert Oracle Database Architecture to gain a solid and accurate understanding of how locking and concurrency are dealt with by Oracle Database. Also learn how the Oracle Database architecture accommodates user transactions, and how you can write code to mesh with how Oracle Database is designed to operate. Good transaction design is an important facet of highly-concurrent applications that are run by hundreds, even thousands of users who are all executing transactions at the same time. Transaction design in turn relies upon a good understanding of how the underlying database platform manages of the locking of resources so as to prevent access conflicts and data loss that might otherwise result from concurrent access to data in the database. Oracle Database Transactions and Locking Revealed covers in detail the various lock types, and also different locking schemes such as pessimistic and optimistic locking. Then you’ll learn about transaction isolation and multiversion concurrency, and how the various lock types support Oracle Database’s transactional features. You’ll learn some good tips for transaction design, as well as some bad practices and habits to avoid. Coverage is also given to redo and undo, and their role in concurrency. This is an important book that anyone developing highly-concurrent applications will want to have handy on their shelf.

Ob Kaufverhalten, Grippewellen oder welche Farbe am ehesten verrät, ob ein Gebrauchtwagen in einem guten Zustand ist – noch nie gab es eine solche Menge an Daten und noch nie bot sich die Chance, durch Recherche und Kombination in der Daten¬flut blitzschnell Zusammenhänge zu entschlüsseln. Big Data bedeutet nichts weniger als eine Revolution für Gesellschaft, Wirtschaft und Politik. Es wird die Weise, wie wir über Gesundheit, Erziehung, Innovation und vieles mehr denken, völlig umkrempeln. Und Vorhersagen möglich machen, die bisher undenkbar waren. Die Experten Viktor Mayer-Schönberger und Kenneth Cukier beschreiben in ihrem Buch, was Big Data ist, welche Möglichkeiten sich eröffnen, vor welchen Umwälzungen wir alle stehen – und verschweigen auch die dunkle Seite wie das Ausspähen von persönlichen Daten und den drohenden Verlust der Privatsphäre nicht.

Gibt es ein Rezept für Verkaufserfolg? Die meisten Führungskräfte im Vertrieb verweisen hier zuerst auf eine gute Kundenbeziehung – und sie liegen falsch damit. Die besten Verkäufer versuchen nicht nur einfach eine gute Beziehung zu ihren Kunden aufzubauen – sie stellen primär die Denkweisen und Überzeugungen ihrer Kunden in Frage. Basierend auf einer umfassenden Studie mit mehreren tausend Vertriebsmitarbeitern in unterschiedlichen Branchen und Ländern, zeigt "The Challenger Sale", dass das klassische vertriebliche Vorgehen mit dem Aufbau von Beziehungen immer weniger funktioniert, je komplexer die Lösungen sind. Doch wie unterscheiden sich Fertigkeiten, Verhaltensweisen, Wissen und Einstellung der Spitzenverkäufer vom Durchschnitt? Die Studie zeigt deutlich, dass die Verhaltensweisen, die den Challenger so erfolgreich machen, replizierbar und strukturiert vermittelbar sind. Die Autoren erklären, wie fast jeder Verkäufer, ausgestattet mit den richtigen Werkzeugen, diesen Ansatz erfolgreich umsetzen kann und so höhere Kundenbindung und letztendlich mehr Wachstum generiert. Das Buch ist eine Quelle der Inspiration und hilft dem Leser, sein Profil als Vertriebler zu analysieren und gezielt zu verändern, um am Ende kreativer und besser zu sein.
