Structured Query Language (SQL)
SQL, or Structured Query Language, is the standard language for communicating with databases. Understanding SQL allows you to update, organize, and query data in relational databases, as well as alter data structures (schema). Because nearly all data analysts will need to use SQL to retrieve data from a company’s database, it is likely the most critical skill to acquire. In reality, technical screening using SQL is prevalent in data analyst interviews.

Statistical Programming
Statistical programming languages, such as R or Python, make it possible to do complex analyses in ways Excel cannot. With the ability to build programs in these languages, you may effectively clean, analyze, and display enormous data sets. Both languages are open source, and it would be prudent to learn at least one. There is considerable disagreement over the optimal language for data analysis. Both languages are capable of doing comparable data science tasks. Python is the more popular and generally simpler language to learn (particularly if it is your first), but R was built expressly for analytics.

Machine Learning
The growth of machine learning, a subfield of artificial intelligence (AI), has become one of the most significant in data science. This competency focuses on developing algorithms to discover patterns in large data sets, with the accuracy of these algorithms increasing with time. The more data an algorithm for machine learning examines, the “smarter” it gets, enabling more precise predictions. Generally, data analysts are not expected to be experts in machine learning. But improving machine learning abilities might provide you a competitive edge and put you on the path to a data scientist profession in the future.

Probability and Statistics
Statistics is the mathematical and scientific discipline concerned with the collection, analysis, interpretation, and presentation of data. This may seem familiar since it closely resembles the job description of a data analyst. With a solid foundation in probability and statistics, you will be better able to: spot patterns and trends in the data; avoid introducing biases, fallacies, and logical mistakes into your research; and create accurate and reliable findings.

Data Management
Data management is the collection, organization, and storage of data in an efficient, secure, and cost-effective manner. While some companies have positions devoted to data management, such as data architects and engineers, database administrators, and information security analysts, data analysts often manage data. Different firms utilize different data management systems. As you grow your skill set, it might be beneficial to have a comprehensive grasp of how databases operate in both physical and cloud-based contexts.
