摘要
1. 下列哪项需要对象数据库技术?a.将员工图片保存到磁盘b.提取员工图片c.将员工图片与简单的员工数据一起提取和处理d.将员工图片在屏幕上显示。2. 下面哪一个支持面向对象的概念?a. SQL 1 b. SQL 2 c. SQL 3 d.以上所有3。对象在纯面向对象语言中隐藏了实现细节，例如属性和内部过程，不让外界看到。这些属性被称为:a.抽象b.封装c.继承d.多态性4。由于严重的性能问题，在当今的对象关系DBMS中，哪些对象概念通常没有实现?a.数据抽象b.封装c.继承d.方法(即过程)下列哪一项不适用于今天的对象关系DBMS?a.处理媒体数据的函数调用是数据库语言的一部分b.提供了专门的存储结构c.不考虑可靠性d.优化了复杂数据和关系数据的组合访问
