Existing multimedia data models such as the of multimedia data model based on the of Non First Normal Form (NF2), object oriented data models and hyper media data models do not meet the needs of MGIS.
但现有的几种多媒体数据模型(NF 2模型、面向对象模型和超媒体模型等)尚不能满足MGIS数据管理的要求。
The interpretation of policy documents is based on the normal form, though, so that's what I'll cover first.
策略文档的解释是基于标准形式的，因此我首先对它做一介绍。
Most experts would suggest that designers strive to follow the first three rules, so that the data is said to be in third normal form.
大多数专家都会建议设计者尽量遵从前三条规则，由此得到的数据就可以说是符合第三范式。
An improved adjoint operator method is employed to compute the third order normal form of six dimensional nonlinear dynamical systems and the associated nonlinear transformation for the first time.
