Data analysts and programmers were different professions. Although both were related to data and computer technology, there were obvious differences in job responsibilities, job content, and skill requirements. In terms of job responsibilities and job content, programmers were mainly responsible for writing code to develop software, applications, websites, etc., such as developing Java software, Android development, game development, etc. They needed to build the project from scratch, analyze the code, and input the code, and finally complete the entire process from the idea of the project to the construction. Data analysts collected, organized, and analyzed existing data to discover patterns and trends in the data and provide decision-making support. For example, by analyzing the sales data of the top 100 real estate companies, November's Purchasing Index data, and other economic data to explain economic phenomena or provide business recommendations. In terms of skill requirements, programmers needed to be proficient in one or more programming languages. For example, software development required mastery of Java, Android development language, and so on. They also needed to be familiar with development framework, database, algorithms, and other knowledge. Although data analysts also needed to master some programming and tools, such as Python programming language, pandas data sorting and statistics analysis tools, Mystical database, etc., they were more focused on data analysis methods, data mining techniques, statistics knowledge, and data visualization skills. For example, they used data perspective, vlookups, and other formulas in Excel to process data, and used matplotLib and seaborn library packages for graphic visualization. In summary, data analysts were not programmers. " When a programmer meets a psychologist " is equally exciting. Everyone is welcome to click to read it!

Data analysis was usually tiring. In terms of work intensity, the work of data analysts involved processing a large amount of data, such as data cleaning. When data was collected from different sources, there would be problems such as missing values, duplicate values, and outlier values. The cleaning process to ensure the quality of data could be very tedious and time-consuming. Data visualization required the analysis results to be transformed into easy-to-understand charts and graphs. In a big data environment, processing massive records required powerful computing power and efficient algorithms, as well as a high sense of responsibility and rigorous logical thinking skills, which would increase work pressure. Overtime depended on the company's culture and project needs. Some companies had an overtime culture, and non-IT positions might also work overtime. However, if you could arrange your working hours reasonably and use efficient tools, you could reduce your workload. From a personal point of view, people who are new to data analysis need to constantly learn new skills, such as learning Python for data analysis, mastering machine learning algorithms, understanding database management, etc. They may feel tired at first, but as their experience and skills increase, this feeling will gradually reduce.
