Why do we use expressions in SSIS?
In Integration Services, expressions can be used to define conditions for CASE statements, create and update values in data columns, assign values to variables, update or populate properties at run time, define constraints in precedence constraints, and provide the expressions used by the For Loop container.
What is the use of expression task in SSIS?

What is Fuzzy Lookup in SSIS?

What is full cache in SSIS?
The Full Cache option tell SSIS to consume all your reference data into memory and then perform its lookups on that data.
