How is the data collected? This problem is also a problem that all people who do SEO should consider, and the ability that should be mastered, most of the ** revision or enterprise promotion activities will first do a good job of data collection, analyze the rules clearly to make some adjustments and plans, here is the solution to this problem.

Survey. As mentioned earlier, most large** will use the form of questionnaire survey to investigate the needs of users when collecting **data, this form of collecting user data is the most intuitive, but depending on this form is not suitable for small **!

First of all, the traffic of the small ** itself is less, and the second is that the questionnaire survey is relatively complex, and there is more content that needs to be filled, and many users may not be patient, and finally the small ** gets less accurate data through this form, because there are few users, so the data ratio is relatively not so accurate!

In fact, I think that the small ** survey, should be through the "yes" and "no" form of the survey, if you ** have a large number of users, then you can use fill-in-the-blank questions, the number of users is small, try to use multiple choice questions, or even 2 answers of multiple choice questions.

Team discussions. Revision**or to modify**, I think the focus is on the results of the team discussion, even if there is a small change in me**, I will discuss with you through QQ groups and other forms, what needs to be changed, what should be changed, how to change and other issues.

In fact, I think the QQ group should be the best in the form of discussion, and the people in the webmaster circle in the QQ cluster can highlight the inconsistent views by issuing different suggestions. It's very beneficial to have both the key setter and the user aware that their own views may be different from those of others.

Statistics. The most primitive way of data collection, but also the most reliable way of data collection, for example, we can often see that a large-scale ** cooperation page will write basic data such as monthly views, the proportion of men and women, and the proportion of regions, most of which are based on statistics.

How is the data collected? After reading the content of the above article, do you understand how to collect data from the Liangliang rental station in front of the network? As long as you do a good job in the above articles, I believe you will definitely be able to prepare for data collection and data statistics. **。

In general, data analysis and data visualization are heard more often, and data collection is heard relatively less. Data collection generally refers to data being stored in various business systems or manually entered into databases. Here we have to mention a function called data filling.

The data filling function is a new product launched by Yixin Huachen, a one-stop data analysis platform - a feature of data collection in ABI. The data filling function can backfill the report, fill in the missing data, and make a new filling form for data entry, which truly realizes the integration of data analysis and filling. The backfill form supports the import of Excel data, so that the large amount of data is no longer a problem, and at the same time, it supports data review to ensure the correctness of the data.

Yixin Huachen's one-stop data analysis platform - ABI is an all-round product of Qiaomu, which integrates core functions such as data source adaptation, ETL data processing, data modeling, data analysis, data filling, workflow, portal, and mobile application. Among them, data analysis and data visualization are the strengths of Exin ABI and its core functions. In addition to Chinese-style complex reports, dashboards, and large-screen reports, ABI also supports self-service Xiaozaosen analysis, including drag-and-drop multi-dimensional analysis, Kanban and Kanban sets, and business users can carry out exploratory self-service analysis as they want by simply dragging and dropping.

At the same time, the word impromptu report and slide report make the report more brilliant. The data visualization of Exin ABI is also rich and colorful, and its reports have hundreds of built-in visualization elements and graphics. It not only supports more than 80 kinds of statistical charts, but also includes maps and GIS maps of the world and various provinces and cities in China, and thousands of visualizations can be derived through design and collocation.

At the same time, ABI also supports dynamic and cool cool screen analysis, unique 3D panoramic perspective, and freely and quickly produces various interactive conventional screen and large screen reports, turning creativity into reality.

Data collection should focus on the following aspects:

1) On time (in time). Monitoring data should be collected in a timely manner according to a certain monitoring frequency or forecast needs.

2) Comprehensive. All data related to the monitoring of landslides and influencing factors should be collected each time.

3) Accurate. Make sure every record is accurate. If obvious errors are found on site, retest should be conducted; and eliminate human and mechanical errors as much as possible.

1) The data collection of geological boreholes in coal fields is based on coal exploration projects (or mining areas and well fields). Data collection is also carried out on a project-by-project basis for borehole data such as inspection and verification of geophysical anomalies or during the survey phase.

2) The construction of the geological borehole data of the coal field adopts the method of comprehensive geological cataloging, that is, the stratification of the rock strata and coal seam characteristics in the borehole is used as the basic unit of the catalog.

3) Take the project (or mining area) as the unit, fill in the main analysis items of industrial analysis and elemental analysis of raw coal, refined coal and coal ash samples, the types of test samples and test results, including the characteristic data of coal dust, gas quality, coal weight, colloidal layer leakage, and pure lead.

4) When there is a big difference between the analysis method, test items and the requirements of filling in the form, explain them in the remarks.
