توضیحاتی در مورد کتاب اوراکل 9i. Application Developers Guide - اشیای بزرگ (LOBs) با استفاده از جاوا (JDBC)

راهنمای توسعه‌دهنده برنامه Oracle 9i-اشیاء بزرگ (LOB) حاوی اطلاعاتی است که ویژگی‌ها و عملکرد محصولات Oracle 9i و Oracle 9i Enterprise Edition را توضیح می‌دهد. Oracle 9i و Oracle 9i Enterprise Edition دارای ویژگی های اولیه یکسانی هستند. با این حال، چندین ویژگی پیشرفته فقط با نسخه Enterprise در دسترس هستند و برخی از آنها اختیاری هستند. برای استفاده از قابلیت Partitioning، گزینه Partitioning را انتخاب کنید.


توضیحاتی درمورد کتاب به خارجی

Oracle 9i Application Developer's Guide-Large Objects (LOBs) contains information that describes the features and functionality of Oracle 9i and Oracle 9i Enterprise Edition products. Oracle 9i and Oracle 9i Enterprise Edition have the same basic features. However, several advanced features are available only with the Enterprise Edition, and some of these are optional. To use the Partitioning functionality, select the Partitioning option.
