Physical Database Design or Computer Viruses for Dummies

Physical Database Design: The Database Professional's Guide to Exploiting Indexes, Views, Storage, and More

Author: Sam S Lightston

The rapidly increasing volume of information contained in relational databases places a strain on databases, performance, and maintainability: DBAs are under greater pressure than ever to optimize database structure for system performance and administration.

Physical Database Design discusses the concept of how physical structures of databases affect performance, including specific examples, guidelines, and best and worst practices for a variety of DBMSs and configurations. Something as simple as improving the table index design has a profound impact on performance. Every form of relational database, such as Online Transaction Processing (OLTP), Enterprise Resource Management (ERP), Data Mining (DM), or Management Resource Planning (MRP), can be improved using the methods provided in the book.

· The first complete treatment on physical database design, written by the authors of the seminal, Database Modeling and Design: Logical Design, 4th edition.
· Includes an introduction to the major concepts of physical database design as well as detailed examples, using methodologies and tools most popular for relational databases today: Oracle, DB2 (IBM), and SQL Server (Microsoft).
· Focuses on physical database design for exploiting B+tree indexing, clustered indexes, multidimensional clustering (MDC), range partitioning, shared nothing partitioning, shared disk data placement, materialized views, bitmap indexes, automated design tools, and more!

Computer Viruses for Dummies (Dummies Series)

Author: Peter H Gregory

Computer viruses—just the thought of your trusty PC catching one is probably enough to make you sick. Thanks to the cyber-sickies who persist in coming up with new strains, there’s a major new cyberattack nearly every day. Viruses sneak in, usually through e-mail.

Fortunately, there are ways to inoculate and protect your computer. Computer Viruses For Dummies helps you:



• Understand the risks and analyze your PC’s current condition

• Select, install, and configure antivirus software

• Scan your computer and e-mail

• Rid your computer of viruses it’s already caught

• Update antivirus software and install security patches

• Use firewalls and spyware blockers

• Protect handheld PDAs from viruses

• Adopt safe computing practices, especially with e-mail and when you’re surfing the Net



Written by Peter H. Gregory, coauthor of CISSP For Dummies and Security + For Dummies, Computer Viruses For Dummies goes beyond viruses to explain other nasty computer infections like Trojan horses, HiJackers, worms, phishing scams, spyware, and hoaxes. It also profiles major antivirus software to help you choose the best program(s) for your needs.

Remember, if you don’t protect your computer, not only do you risk having your computer infiltrated and your data contaminated, you risk unknowingly transmitting a virus, worm, or other foul computer germ to everybody in your address book! This guide will help you properly immunize your PC with antivirus software now and install updates and securitypatches that are like booster shots to keep your software protected against new viruses.
