翻译原文:In flat databases [2], records are organized according to a simple list of entities; many simple databases for personal computers are flat in structure. The records in hierarchical databases are organized in a treelike structure, with each level of records branching off into a set of smaller categories. Unlike hierarchical databases, which provide single links between sets of records at different levels, network databases create multiple linkages between sets by placing links, or pointers, to one set of records in another; the speed and versatility of network databases have led to their wide use in business.
翻译答案:在非结构化的数据库中,按照实体的一个简单列表组织记录;很多个人计算机的简易数据库是非结构的。层次型数据库按树型组织记录,每一层的记录分解成更小的属性集。层次型数据库在不同层的记录集之间提供一个单一链接,与此不同,网络型数据库在不同记录集之间提供多个链接,这是通过设置指向其它记录集的链或指针来实现的。网络型数据库的速度及多样性使其在企业中得到广泛应用。
读完一本书原文:They weren't even cracked.
She stood frozen with the eggs in her hands while I dumped the rest of the trash. “Why did you throw them out?” she asked, but her voice didn't
sound like Juli Baker's voice. It was quiet. And shaky.
So I told her we were afraid of salmonella poisoning because her yard was a mess and that we were just trying to spare her feelings. I told it to her like we were right and she was wrong, but I felt like a jerk. A complete cluck-faced jerk.
Then she tells me that a couple of neighbors have been buying eggs off her. Buying them.
And while I'm coming to grips with this incredible bit of news, she whips out her mental calculator. “Do you realize I've lost over a hundred dollars giving these eggs to you?” Then she races across the street in a flood of tears. 翻译答案:连裂缝都没有。她手里拿着鸡蛋,定定地站在那里,而我倒掉剩下的垃圾。
“你为什么要扔掉它们?”她问,可听上去完全不像平时的朱莉.贝克。那声音很轻,带着颤抖。
于是,我告诉她我们害怕被传染沙门氏菌,因为她家的院子实在太脏了,而且我们不想伤害她的感情。我说的好像我们是对的她才是错的,但我觉得我自己就像个混蛋,一个假惺惺的混蛋。
她说,有几家邻居从她那里买鸡蛋。花钱买。
当我的脑子还在处理这个惊人的消息,她已经迅速地心算过了。“你有没有想过,为了给你这些鸡蛋,我已经损失了超过一百美元?”她的眼泪汹涌而出,转身跑过街道。
