The purpose of the system is to use big data technology to analyze the log data of Sina Weibo, so as to explore the characteristics and trends of user behavior, content dissemination and mobile devices. This research provides valuable reference and assistance for companies and individuals when formulating marketing strategies, designing products and providing user services. Using the Hive platform, the system can process and analyze a large amount of Weibo data, providing us with statistical information on the number of users, the number of Weibo reposts, the number of Weibo posts posted by users, and Weibo data containing pictures.
After data processing and analysis, we came to the following findings: Sina Weibo is one of the most influential social media platforms in China, with a large user base and content coverage. Among them, some users have a very high number of retweets on Weibo, which has a wide range of influence and communication capabilities. On the other hand, some users post a large number of microblogs, while others have relatively few, which may be related to factors such as user interest and activity. Microblogs with pictures show strong dissemination power and influence on social media platforms. In addition, the number of users who use iPhone to post Weibo is also very large.
In general, through the big data analysis of Sina Weibo logs, we have a deep understanding of the characteristics and trends of user behavior, content dissemination, and mobile devices, which provides a useful reference for us to better understand and apply social media data and auxiliary. These research results also provide valuable enlightenment and suggestions for companies and individuals in marketing strategies, product design, and user services.
As one of the largest social media platforms in China, Sina Weibo has hundreds of millions of users and generates a huge amount of data every day. Behind these huge data, there is a wealth of information such as user behavior habits, interest preferences, and emotional states. Through this information, we can understand social phenomena, predict market trends, support business decisions, and even monitor public opinion in real time.

Introduction to Big Data Analysis
With the continuous development of science and technology, the amount of data continues to grow, and the traditional data processing methods can no longer meet the needs of data analysis. As a new data analysis method, big data analysis has attracted more and more attention [7]. Big data analysis refers to the collection, processing and analysis of large-scale data through the application of various data science techniques and algorithms to discover the information and value behind the data and provide support for enterprise decision-making and business process improvement. This article will introduce big data analysis from the definition, characteristics, application and development trend of big data.

System Design and Implementation
This research aims to conduct big data analysis on Sina Weibo logs based on the Hive platform, and deeply explore the characteristics and trends of Sina Weibo in user behavior, content dissemination, mobile devices and other aspects. Provide useful reference and suggestions on product design, user service, etc. The main design methods include big data analysis through hiveSQL, design code modules with specific indicators and analytical thinking, and big data analysis in hive in Hadoop, The specific design ideas are as follows.
First of all, this paper collects the log data of Sina Weibo, including the total number of Weibo, the number of users, Weibo content, the number of forwarding, publishing equipment and other information. Then, this paper processes and analyzes these data through the Hive platform.
First, by querying the total number of Weibo and the number of independent users, this paper finds that Sina Weibo, as one of the largest social media platforms in China, still has a very wide user group and content coverage. This provides basic data for subsequent analysis.
Second, this paper analyzes the total number of retweets of all microblogs of each user, and outputs the top three users, and finds that the microblogs of these users have high influence and spreading power. This shows that on social media platforms, some users have higher influence and communication capabilities, which need to be paid attention to.
Third, by querying the top three microblogs that have been forwarded the most times and identifying the publishers of the microblogs, this paper finds that these microblogs have high attention and influence. This provides a clue for this paper to study the dissemination of microblog content in depth.
Fourth, this paper queries the total number of microblogs posted by each user and stores the results in a temporary table. By analyzing the data of the temporary table, this paper finds that some users have a very large number of microblogs, while some users have relatively few. This provides the basic data for the in-depth study of user behavior and hobbies in this paper.
Fifth, this paper conducts a statistical analysis on the microblog data with pictures, and finds that quite a few microblogs have pictures. This shows that the dissemination and influence of images on social media platforms cannot be ignored, and it provides a new idea for this paper to explore the way of content dissemination.

In Weibo log analysis, querying the total amount of Weibo has many advantages. First of all, it can help this article understand the current topic heat and user activity, thereby helping this article to formulate better marketing strategies and promotion plans. Secondly, it can help this article understand user behavior trends, such as which topics and content are more popular, as well as the time and frequency of users posting Weibo, etc., so as to help this article better understand the target audience and make more targeted decisions .
Microblog total query
By analyzing the number of unique users of a hot topic, you can obtain data, and further analyze indicators such as forwarding volume, number of comments, and number of likes, so as to understand the influence of the topic and user participation. If the amount of forwarding is high, it can be considered that the topic has a better spread effect on social media; if users often post pictures, it can be considered that the topic has a high visual correlation, thereby providing guidance for content creation.
Query the number of unique Weibo users
In Weibo log analysis, it is very useful to know the total number of all Weibo retweets of a user. It can help analyze information such as the influence of the account, the audience and the popularity of the topic.
For a given Weibo account, you can use the SQL query statement similar to the one mentioned above to calculate the total number of retweets of all its Weibo accounts, and output the top three users with the most retweets.

Most retweeted Weibo users
In microblog log analysis, query the total number of microblogs posted by each user, and store them in a temporary table. The advantage is that the total number of microblogs posted by each user can be easily counted. This is very useful for analyzing user behavior, evaluating user influence, and formulating marketing strategies. At the same time, storing the results in a temporary table can also avoid repeated calculations and improve query efficiency.

The number of microblogs posted by each user
In Weibo log analysis, it is very useful to query and count Weibo data with pictures. This process can help users obtain data and insights related to pictures on the Weibo platform, and help users better understand and analyze the behavior and interests of Weibo users.
Query and count with pictures
In Weibo log analysis, counting the number of unique users who use iPhone to send Weibo has many benefits. First of all, this can help this article understand what devices users use Weibo on, as well as the usage habits and preferences of users of different devices. Secondly, this can help this paper to better optimize the Weibo application and ensure that it can provide a good user experience on different devices. Finally, this can help this article to better understand market demand and user trends, so as to formulate better marketing strategies and promotion plans.
Weibo Statistics The number of users who use iPhone to post Weibo
Microblog log analysis refers to the data analysis of microblogs posted by users on the microblog platform to understand user behaviors, preferences, trends, etc. In this process, the number of posts on 2015-08-29 is queried and put into the table.

Next, this article combines the following two query statements to further describe its functions:
(1) Query the number of posts on 2015-08-29
Analyze the number of all posts on the day 2015-08-29. However, it simply returns a number and cannot visually represent the data. Moreover, if this article needs to use this query statement multiple times, it is very cumbersome to re-enter this statement each time. At this time, this article can use the second query statement to create a new table to facilitate subsequent query and analysis.
(1) Put the query results into the table
This article can more conveniently process and analyze data, such as classifying, sorting, and counting data. Moreover, this article can export the data of this table to other programs or tools for deeper analysis and mining.
To sum up, putting the number of postings of the query 2015-08-29 into the table can facilitate subsequent analysis and processing. In this way, this paper can gain a deeper understanding of user behavior and needs, and provide valuable data support for brand marketing, market research, etc.
Query the number of posts on 2015-08-29
In Weibo log analysis, counting the "number of users of ipad client" is a very useful function. This function can help analysts and marketers better understand the types of devices users use when using Weibo, so as to formulate more targeted marketing strategies and improve marketing effects.
Specifically, by counting the number of users of the ipad client, the following benefits can be drawn:
(1) Better understanding of user behavior: Knowing the types of devices used by users can more accurately determine user preferences, needs, and behavioral habits. For example, iPad users are more likely to use Weibo on weekends or evenings, so relevant content can be pushed during these time periods to improve the exposure and dissemination effect of the content.
(2) Formulate more targeted marketing strategies: On the basis of understanding user behavior, we can formulate more targeted marketing strategies according to user preferences and needs of different device types. For example, for iPad users, more high-definition pictures and videos can be pushed to provide a richer reading experience.
(3) Optimizing delivery resources: Counting the number of users of the ipad client can help marketers better understand the allocation of delivery resources, and then optimize. For example, if you find that the proportion of iPad users is relatively high, you can give priority to placing advertisements suitable for iPad devices to improve the advertising effect.
On August 29, 2015, count the number of microblogs posted on Weibo using the iPad client. Through this number, this article can preliminarily estimate the number of users using the iPad client. Of course, this result may not be very accurate, because a user may use different devices to post Weibo on the same day. However, through this query statement, the device type of the user can be preliminarily known, so as to provide a basis for subsequent analysis and marketing work.
The source of statistical data is the number of users of the ipad client
