In today's world, data is everywhere. From the information we share on social media to the purchases we make online, data is constantly being collected, analyzed, and used to make decisions that affect our lives. But what is the true value of this data, and how can we use it to uncover the truth? At its core, data is like a roadmap to the truth. It can help us understand patterns, trends, and correlations that we may not have otherwise noticed. For example, data analysis can reveal that certain health conditions are more prevalent in certain geographic areas, or that certain demographics are more likely to engage in certain behaviors. By following the signs in the data, we can begin to piece together a more complete picture of the world around us. But following the signs isn't always easy. Sometimes, the data leads us to unexpected places. We may uncover uncomfortable truths, or we may find that our assumptions were incorrect. In these cases, it can be tempting to ignore the da

Structured Query Language (SQL) is a programming language used to manage and manipulate relational databases. SQL is used by data analysts and data scientists for extracting, transforming, and analyzing data stored in databases. In this blog, we will discuss the most commonly used SQL functions that are used in real-world problems and can help solve up to 80% of the work required in data analysis. SELECT: SELECT is the most frequently used SQL function. It is used to retrieve data from one or more tables in a database. This function allows you to select specific columns, rows, or a combination of both from a table. The syntax for the SELECT statement is: SELECT column_name(s) FROM table_name WHERE: The WHERE function is used to filter data from a table based on a specific condition. It is used in combination with the SELECT function to retrieve specific data. The syntax for the WHERE statement is: SELECT column_name(s) FROM table_name WHERE condition GROUP BY: The GROUP BY function is
