对于初学者，这一账单表中包含了各种不正常数据垃圾。
For starters, the bills table has all sorts of de-normalized junk in it.
网络中的流量数据被分为正常数据和攻击数据两个部分。
It suppose that the traffic data on a normal network are normal data, so the data on normal network should be captured as normal data.
假定正常数据分布的开销评估可能并不能最好地反映查询使用不同参数时的实际开销。
A cost estimation that assumes normal data distribution may not best reflect the real cost of a query when different parameters are used.
在搜集，处理可靠性数据时，必须认真研究产品分类，设计调研表格，排除非正常数据。
When collecting and processing reliability data it is necessary to carefully study the classification of products, lay-out of investigating forms and removal of abnormal data.
在这种情况下，优化器会使用一个通用规则或者默认值以正常数据分布率来评估得到一个平均开销值。
In this case, the optimizer USES a generic rule or a default value to estimate an average cost by assuming normal data distribution.
它通常根据系统的正常数据流背景来检测入侵行为，故而也有人称其为“启发式特征检测”。
It usually measures the behavior of invading according to the normal dataflow background of the system, so is called "the heuristic characteristic measures".
提出了一种k-均值聚类算法和SOM自组织神经网络算法相结合的异常检测模型，使得系统可以更好的分类正常数据流和异常数据流，以此来防范未知的攻击。
Secondly, the anomaly detection model based on K-means algorithm and SOM network is constructed. It can classify the normal and abnormal network data stream so better to detect the unknown attack.
