With the acceleration of digital transformation, the demand for data analysts and data engineers continued to increase. All industries valued the value of data. From retail to finance, from medical to manufacturing, data applications were everywhere. According to a market research report, the demand for data-related positions will increase by 20% per year in the next few years, which means that they have a broad career development space. However, the stats analyzer profession also faced some challenges. On the one hand, a large number of job opportunities were concentrated in cities such as Beijing, Shanghai, Guangzhou, and Hangzhou. These cities were filled with talent and the pressure of competition was high. On the other hand, with the popularity of artificial intelligence and machine learning technology, companies had higher requirements for data analysts. Not only must they have solid data analysis skills, but they also needed to master machine learning algorithms to deal with complex data sets. Moreover, after more than 20 years of development, many products and operating methods of the Internet have become increasingly mature. Many companies 'businesses have stabilized, and the demand for data has fallen back to "looking at data" to maintain operations. The problems that need to be solved through data analysis have drastically decreased. In recent years, technological development has spawned many data analysis and operation tools, which have lowered the threshold for product managers and operators to use data. Business personnel rely on tools to solve many problems that used to be solved by data analysts, resulting in a decrease in job demand and an increase in the threshold of existing positions. The change in the national economic cycle and the impact of the epidemic have caused many companies to live carefully. As a "high-cost" functional department, the risk of data being cut is extremely high. The promotion ceiling was obvious, and most companies had smaller teams. The career paths of data analysts and data engineers were diverse and could meet the career planning needs of different groups of people. Data analysts could be promoted from junior analysts to senior analysts, data scientists, and even data department managers. Data scientists were the common development direction of data analysts and data engineers. This position required both professional skills. At every stage, one had to constantly learn new skills to improve their professional level. " When a programmer meets a psychologist " is equally exciting. Everyone is welcome to click to read it!

The classic introductory books on data analysis were recommended as follows: " Python Data Analysis Basics ": This book is a classic in the field of data analysis in China. It mainly introduced the basic knowledge and common tools of Python data analysis, including data cleaning, data visualization, machine learning, etc. " Principles of statistics ": This book is a classic textbook in the field of statistics. It provides a comprehensive introduction to the basic concepts, principles, and methods of statistics, including probability theory, hypothesis testing, regress analysis, and analysis of variation. 3 " Data structure and algorithm analysis ": This book is a classic in the field of data structure and algorithm analysis. It mainly introduced the basic concepts of data structure, the design and analysis of algorithms, sorting algorithms, search algorithms, etc. 4 " R Language Practicals ": This book is an introductory textbook for the R language. It mainly introduced the basic concepts, grammar, and commonly used tools of the R language, including data visualization, statistical analysis, machine learning, and other aspects. The four books above were classic textbooks in the field of data analysis. They were of high reference value for beginners. However, it was important to note that data analysis was a broad field. The specific knowledge and skills needed to be learned still needed to be determined according to one's actual needs and interests.

Data analysts were not programmers. A programmer was a professional who was engaged in program development and program maintenance. Data analysis referred to the use of appropriate statistical analysis methods to analyze a large amount of collected data, summarize, understand, and digest them to extract useful information and form conclusions. It was the product of the combination of mathematics and computer science. The work content of the two was different, but there might be collaborations in some projects.

In 2021, the big data analyst course system will be launched. In 2023, there will be CPDA data analyst certification courses to help data analysts lay a solid foundation in data analysis. The learning outline includes data and data analysis, using statistics to make data fly, key factors affecting business indicators, and many other aspects. There were also CDA data analyst related courses. This was a set of scientific, professional, and international talent assessment standards. It was divided into three levels, CDA Level I, II, and III. It involved many industries and positions. The certification standards were jointly developed by experts in the field of data science and were revised and updated annually. " When a programmer meets a psychologist " is equally exciting.

Compared to programmers and algorithm engineers, the workload of data analysts was relatively low. The work of a data analyst was not like that of a programmer or algorithm engineer. A project was a project that required one to work hard, think hard, and rack their brains. However, data analysts faced different work pressures at different stages. For example, junior data analysts might face the challenges of chaotic data management and tedious daily work. They needed to spend a lot of time sorting and cleaning data to remove errors, repetitions, missing values, and other data. However, this was a necessary path for growth, and there were many paths to choose from in terms of development prospects. Different paths might have different work pressures and levels of fatigue. For example, developing into a data mining engineer might require more knowledge reserves and the ability to deal with complex tasks. As a data analysis clerk, the investment cycle was shorter, but the upper limit of income was higher, and the work pressure might be relatively lower.

Education big data analysis was a field that involved many aspects. From its development, in the early exploration stage (1980 - 2000), the concept of big data was proposed. At that time, the development of information technology prompted people to realize the problems brought about by the increase in data volume. By the time of the full-scale outbreak in 2000 - 2012, the characteristics of big data were defined as many aspects such as large volume, fast speed, and variety. In the field of education, for example, Xi'an Jiao Tong University had established a real-time monitoring big data platform for teaching quality. The platform used a variety of technologies to achieve accurate collection, evaluation, supervision, and assistance in the classroom. It helped teachers improve their teaching methods and improve their teaching efficiency through reviewing, student feedback, and big data statistics. The platform could automatically collect a large number of courses and data related to student growth in real-time, and use a variety of algorithms to mine the characteristics that reflect the quality of classroom teaching to solve the problem of accurate evaluation of classroom teaching. In addition, big data also played a certain role in compulsory education enrollment. For example, the compulsory education enrollment meeting would carry out the sunshine enrollment special action according to relevant policies, which may also involve the management and analysis of enrollment data by big data to ensure the fairness and fairness of enrollment work. At the same time, there were also theoretical results in the research of educational big data. The relevant books elaborated on the theory of educational big data, and also provided practical cases and development ideas, providing guidance for the education administrative departments, enterprises, research institutions, and schools to carry out educational big data-related work.
