Mapping SQL to Functional Programming

SQL concepts align closely with functional programming principles. The 'map' function corresponds to SQL's select statement, enabling the selection of specific columns. 'Filter' parallels SQL's where clause, allowing for the exclusion of unwanted records. 'Reduce' functions, such as group by, sum, and count, facilitate data aggregation. Additionally, the 'concat' operator is used to combine streams, functioning similarly to an OR operation. This approach allows for streamlined processing of data streams, where 'join' operations maintain relationships between different data sources based on common keys. Initially, these integrations may seem daunting, but they enhance data manipulation capabilities.
