Answer / Jeet Singh
tMap and tJoin are two fundamental components in Talend used for data transformation. The main difference between them is how they handle data.nn- tMap: It applies a set of user-defined functions to each record passing through the component, changing their structure if necessary.n Example usage: Filtering, aggregating, or modifying fields.nn- tJoin: It combines data from multiple sources based on specified join conditions, like INNER, OUTER, LEFT, RIGHT, FULL etc. Commonly used for joining tables in SQL.n Example usage: Merging records from two different input streams.
