Author: Vicki Courtney
language: en
Publisher: B&H Publishing Group
Release Date: 2007-09-01
When CNN and FOX News asked Vicki Courtney to discuss child safety and the Internet on-air last summer, the best-selling author who is popular among both teenagers and parents knew this urgent issue had to become the core topic of her next book. For sure, gone are the days when kids were safe just as long as they were at home and under your nose. Today’s children can access the world from a growing number of portable gadgets, and depending on what they do with this ability, could potentially invite a world of danger into their lives. Logged On and Tuned Out is a timely wake-up call to low-tech (tuned out) parents whose high-tech (logged on) kids use modern computer and cell phone technology like second nature. In simple language, moms and dads overwhelmed by today’s digital world will learn the imperative basics and checkpoints of Instant Messaging, text messaging, social networking Web sites (MySpace, Facebook), chat rooms, and photo and video uploading. The book even has its own related Web site where parents can download online safety contracts, get updated information about safety filters, and more.

Fully updated for version 10gR2 and provides all necessary transition material from version 9i Includes all three aspects of Oracle database tuning: data model tuning, SQL & PL/SQL code tuning, physical plus configuration tuning Contains experienced guidance and real-world examples using large datasets Emphasizes development as opposed to operating system perspective
