What is Analytical functions?

Analytical functions, in the context of databases and data processing, are calculations performed against a set of rows that are related to the current row. This is in contrast to aggregate functions, which summarize data across multiple rows into a single row. Analytical functions compute values such as running totals, ranks, moving averages, and percentiles, and return these values along with the original rows, allowing for detailed analysis and reporting within a single query. They are commonly used for trend analysis, performance monitoring, and business intelligence.
