size="+1">Introduction</font></b><p>Oracle is the most prevalent Relational Database Management System (RDBMS) in the world. Information technology professionals will find Oracle serving the database needs of the enterprise in manufacturing, financial, pharmaceutical, and telecommunications environments all over the globe. The Oracle database runs on every major machine and under every prominent operating system available. Versions of Oracle exist for platforms from modestly equipped portable computers up to powerful database servers accommodating thousands of concurrent users. Oracle databases act as on-line transaction processing engines, decision support systems, data warehouses, and repositories for web-enabled applications. The prevalence and flexibility of Oracle have given rise to groups of information technology professionals梔atabase administrators, application programmers, and database designers梬hose skill sets are tailored to leveraging an investment in the Oracle database.<p>No information technology professional looks forward to frantic migration efforts or to discarding legacy applications. The very strength of Oracle抯 installed base can make capitalizing on the promise of new technology difficult. One such technology is object orientation. Object oriented databases are certainly not new; industry-wide acceptance of object databases, however, has not been forthcoming. Oracle8, the next major release Oracle, promises transparent support of legacy applications and object oriented extensions. This long-awaited product will generate a considerable amount of questions among Oracle information technology professionals. The answers to these questions are at the heart of this book.<p>The first edition of Oracle How-To posed and answered myriad real-world questions confronting anyone who worked with Oracle7. The idea behind this work was simple and appealing to any Oracle practitioners who explained, 揑 understand what a database does, I know my way around computers in general, and I抦 tired of looking through thousands of pages of documentation only to wind up deciphering railroad diagrams. Just show me how to get my Oracle work done.⌨️ 快捷键说明
