Introduction

Oracle is the most popular relational database management system in the world. Its popularity is the result of several factors:

What This Book Is About

This book is about a new version of the Oracle relational database management system (RDBMS) called Personal Oracle7. Personal Oracle7 is a version of the Oracle product that runs on top of Microsoft Windows 95 and Windows 3.11. Even though Personal Oracle7 is a PC-based version of the Oracle RDBMS, Personal Oracle7 provides almost the same features that exist in the versions of the Oracle RDBMS for large computer systems. As a result, Personal Oracle7 is an excellent tool for developers who intend to design applications for the Oracle RDBMS.

Who Should Read This Book

This book assumes that you're familiar with Microsoft Windows 95 and that you have some experience with a database--;whether relational or nonrelational.
