JOINs in SQL are operations that allow you to combine the rows of two or more tables based on a related column between them. In most real-world applications, analyzing data comprehensively requires more than just considering a single table. For a comprehensive analysis, it is very important and necessary to consider different dimensions, thus, using the JOINs operation allows you to reach a comprehensive analysis. In a relational database, data is often normalized and spread across different tables to reduce redundancy and ensure data integrity. JOINs enable you to bring this scattered data together and provide a unified view that can be used for better analysis and reporting.
