This Study Guide is targeted at IT professionals who are working towards the OCE certification: Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning. The book provides information covering all of the exam topics for the Oracle certification exam: "1Z0-117: Oracle Database 11g Release 2: SQL Tuning". The books in the Oracle Certification Prep series are built in lockstep with the test topics provided by Oracle Education's certification program. Each book is intended to provide the information that will be tested in a clean and concise format. The guides introduce the subject you'll be tested on, follow that with the information you'll need to know for it, and then move on to the next topic. They contain no drills or unrealistic self-tests to bump the page count without adding value.  The series is intended to provide a concentrated source of exam information that is compact enough to be read through multiple times. This series is ideal for experienced Oracle professionals that are familiar with the topic being tested, but want a means to rapidly reinforce their existing skills and bridge any gaps in their knowledge. It is also an excellent option as a second source of information for candidates pursuing certification.

Seven months before the troops landed at Gallipoli, a sailor from Melbourne became the nation's ?rst casualty of World War 1.Able seaman William ?Billy? Williams was shot in the stomach on a narrow dirt road in the dense jungles of east New Britain in what was then known as German New Guinea. Mortally wounded, he died a few hours later.Billy Williams was a member of a small force that captured a radio station at Bita Paka near Rabaul, the capital of the German colony. This was an important military victory, for it led to the surrender of Rabaul six days later and the eventual capture by Australia of German New Guinea. The captured territory was held and administered by Australia until PNG became an independent nation from Australia in 1975. But the event was forgotten, overshadowed by Gallipoli and the role it played in forging the nation's mythology. A book has never before been written on this signi'cant event and it will certainly leave its mark as a major event in military history publishing.
