Description
The newest version of the Oracle DBMS, Oracle8, offers some dramatically different features from previous versions, including better scalability, reliability, and security; an object-relational model; additional datatypes; and much more. To get peak performance out of an Oracle8 system, databases and code need to be designed with these new features in mind. This small book tells Oracle designers and developers just what they need to know to use the Oracle8 features to best advantage.
Full Description
The latest version of the Oracle relational database management system, Oracle8, was released in the summer of 1997. The new version offers some dramatically different features from previous versions, including better scalability, reliability, and security; an object-relational model; additional datatypes; and much more. To get peak performance out of an Oracle8 system, databases and code need to be designed with these new features in mind. This small book tells Oracle designers and developers just what they need to know to use the Oracle8 features to best advantage.
O'Reilly's Oracle Design, released in April 1997, has been very well received by the Oracle community. The design of both databases and applications is an often-neglected area of Oracle, but one that has an enormous impact on the ultimate power and performance of a system. If the initial design is poor, then the most powerful hardware, the most sophisticated software tools, and the most highly tuned data and programs won't make a system run smoothly and efficiently. Oracle Design focuses on both database and code design, including such special design areas as data models, denormalization, the use of keys and indexes, temporal data, special architectures (client/server, distributed database, parallel processing), and data warehouses. Written primarily for Oracle7 (through 7.3), it also takes a look ahead at some of the features announced for Oracle8.
Oracle8 Design Tips is a companion volume for Oracle Design. Written by Dave Ensor and Ian Stevenson, authors of the original volume, the mini-book focuses on the new features of Oracle8 and on the object-relational model of the new version. Virtually all of the advice in the original book is still absolutely on target (regardless of what version of Oracle you are running). But the mini-book updates that advice to tell you how to capitalize on the latest features. Used together, the two volumes provide immensely valuable and up-to-the-minute information for anyone trying to design for the latest version of the Oracle RDBMS.
Chapters include:
1. What's New in Oracle8? An overview of Oracle8 and Oracle's approach.
2. Methodologies for Oracle8. Can traditional methodologies be used for development in an object-oriented environment? What approaches are best for Oracle's new object-relational model?
3. Miscellaneous Oracle8 Enhancements. Discussions of a variety of new features, including triggers and backups.
4. Oracle8's "Big" Features. Design hints for using features that support very large databases, including large objects (LOBs), partitioned objects, indexes and tables, cooperative indexing, etc.
5. Objects. A general discussion of the object-oriented technology that underlies Oracle8--for example, how do such features as encapsulation, inheritance, and polymorphism apply in an Oracle environment?
6. Tools Support for Oracle8. The use of tools like Sedona, Developer/2000, Designer/2000, Object Designer, SQL*Plus, C/C++, and Java with Oracle8.
Colophon
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The insect featured on the cover of Oracle Design is a dragonfly of the family Libellulidae, or common skimmer. Dragonflies, along with damselflies, com prise the order Odonata. Dragonflies are predatory insects. Young dragonflies are aquatic insects. They are equipped with a unique "jet propulsion" ability. By drawing water in through their gills, located in the posterior of their abdomens, and quickly forcing it out again they are able to powerfully propel themselves across the water surface. This technique is used in emergencies when a quick getaway is called for.
Mature dragonflies are among nature's most impressive fliers. Because they achieve great speed and power relative to their size, their flying techniques have been studied extensively by aviation engineers. Dragonflies are able to fly as fast as 35 miles per hour, and to perform impressive mid-air acrobatics. Unlike most flying insects, dragonflies operate their front and rear wings in dependently. They twist their wings slightly on the downstroke, thus creating mini-whirlwinds that move over the wing surface faster than still air would.
Adult dragonflies catch and eat their prey while flying. They fly with their long, bristle-covered legs bent in front of them, forming something like a basket, which they use to scoop up other insects. Dragonflies are quite popular with humans both because of their beauty and grace and because their diet is largely made up of mosquitoes and flies. Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. The cover layout was produced with Quark XPress 3.3 using the ITC Garamond font. Whenever possible, our books use RepKoverTM, a durable and flexible lay-flat binding. If the page count exceeds RepKover's limit, perfect binding is used. The inside layout was designed by Edie Freedman and Nancy Priest and implemented in FrameMaker by Mike Sierra. The text and heading fonts are ITC Garamond Light and Garamond Book. The illustrations that appear in the book were created in Macromedia Freehand by Chris Reilley and Robert Romano. This colophon was written by Clairemarie Fisher O'Leary.
