We break the word multimedia into its component parts, we get multi -meaning more than one ,and media-meaning form of communication. Those types of media include:
¨ . Text
¨ . Audio Sound
¨ . Static Graphics Images
¨ . Animation
¨ . Full-Motion Video
如果我们把multimedia这个词分开，我们便得到multi——多，和media——媒体。媒体类型包括：
· 文本
· 声音
· 静态图像
· 动画
· 动态视频
Logical Structures. Identifying these logical relationships is a job of the data administrator. A data definition language is used for this purpose. The DBMS may then employ one of the following logical structuring techniques during storage access, and retrieval operations [1]:
逻辑结构。确定这些逻辑关系是数据管理者的任务，由数据定义语言完成。DBMS在存储、访问和检索操作过程中可选用以下逻辑构造技术:
All of the Above
You can see that multimedia is by on means just one of the preceding technologies. Because of what hardware can and cannot do, it is often a trade-off between a certain number of static graphics images, audio sound, full-motion video and text. As you may guess, textual information takes the least amount of space to store.
总结
显然多媒体决不是一种从前的技术，由于硬件的能力要权衡选择静态图像、声音、全运动影像和文本，可以推测，文本信息占用存储空间最小。
Even if a multimedia machine had unlimited resources, you would still want to add a combination of these multimedia technologies. For example, although a picture is worth a thousand words, it would be difficult to portray the work of William Shakespeare through pictures only. The same goes for audio sound. You could record the sound of church bells and a narration of the Bible, but at times you would rather have the Bible in textual format, which would allow you to search for certain key words.
即使多媒体机有无限的资源，人们仍想增加融这些多媒体技术于一体的综合技术。例如，尽管“一图胜千言”，但仍难以只用图像表述完莎士比亚的著作，仅用声音当然也不行。你可以记录教堂的钟声和圣经的叙述，但你仍愿使用文本形式的圣经，因为它可以使你查找某些关键词。
