Investors gradually pay more attention to the influence of informatization , therefore the value of evaluate the enterprise informatization strategic implementing performance is apparent.This paper mainly studies the engineering design Institute informatization strategic implementing performance evaluation , due to the current engineering design Institutes are in transition , the design institutes explore how to successfully transform into engineering company , improving the informationization level and management mode , which have an important role in promoting engineering design Institute successfully transformat into the engineering company .
After that using the ETL tool to clean and transformat the source datas which have quality problems , such as errors and inconsistencies data , finally loading data into the data warehouse . 3 .
In addition to the spring , the number of soil microbial in mixed fir-pine forest is more than in pure pine forest . ( 3 ) The soil enzyme and the correlation analysis : In addition to the polyphenol oxidase , between the other four kinds of enzymes ( urease , cellulose enzyme , catalase , invertase ) have a significant correlation , and have the positive correlation , it shows that they are coordinated development , and they work in concert to make soil nutrient elements transformat nutrition elements plant can use .
