Examples
- Preprocessing converts the original dirty data into normalized data . data denoise and compress are the core of the whole process
在整个数据处理过程中,数据除噪和数据压缩是预处理的核心。 - It may also be helpful to developers who find themselves in situations where quick - and - dirty data access is required , but who don t want to compromise too much stability and reuse
本教程还可能有助于那些觉得偶尔需要以快捷但不恰当的方式进行数据访问，但又不想过多危及稳定性和重用的开发人员。 - Aiming at the characteristics of long - term task in workflow , a workflow transaction model based on backward recovery was surveyed , which could avoid the situation of reading dirty data , simplify confliction analysis , and provide efficient workflow transaction management
针对工作流的长时间作业的特点，论文提出了一个基于向后恢复的工作流事务模型，可以避免读脏数据以及简化事务冲突分析，实现高效率的细粒度的工作流事务管理。 - This paper describes the basic features and components of data warehouse system , and deals how to use description - driven technology to integrate different data warehouse systems , how to implement the change from one data schema to another , how to clean dirty data in data transformation process , and how to exchange data among different components or systems . at last , this paper takes two products to illustrate how to implement systems following these principles and methods . these two products are the e - chain system as an application in commerce domain , and the ftedws system as an application in engineer test domain
