Web developers not only create applications that generate such data, it also needs to develop applications and methods that make these data streams meaningful.Generally, Web developers are not enough to cope with the increasing data analysis requirements generated by the management site.

. Task Decomposition method Thought: firstly, the software development project is decomposed into several relatively independent tasks, then the cost of each development task is estimated separately, and the total cost is summed up at the end. 4. Automatic Cost Estimation method To alleviate human labor but to have a lot of empirical data to do the basis, to have the Wolf Howling database system support Co
various descriptive statistics, Web developers do not have any better way to reflect data stream features. Many statistical inference steps (methods for estimating the overall parameters based on sample data) can be fully utilized, but they are not currently applied. For example, the Web access statistics (edited by the current time) are only counted by frequen
record the local area network users of the shared file access operations. Given that there are some deficiencies in the Windows Server file auditing feature that do not meet the requirements of some users for fine-grained analysis of shared file access logs, it is possible to consider deploying a set of dedicated server-shared file logging software to detail the various operational behaviors of LAN users
