1. A method, comprising: receiving a plurality of data records, wherein the plurality of data records includes a first data record and a second data record; processing, by at least one processor, the data records using a plurality of transformation rules, wherein each of the transformation rules corresponds to a respective one of a plurality of tracers, and the plurality of transformation rules includes a first rule and a second rule; adding the tracers to the data records to indicate those of the transformation rules used to process each data record, wherein adding the tracers to the data records comprises appending a tracer code to each data record, or adding a tracer code to a field of each data record, and wherein a first tracer is added to the first data record after processing with the first rule, a second tracer is added to the first data record after processing with the second rule, and the first tracer is added to the second data record after processing with the first rule; determining that a first subset of the plurality of data records fails to satisfy a validation rule; in response to determining that the first subset fails to satisfy the validation rule, writing the first subset to a table of invalid records, wherein each of the invalid records is tagged with tracers indicating those of the plurality of transformation rules used to process the invalid records prior to failing to satisfy the validation rule; writing those of the plurality of data records that satisfy the validation rule to a table of valid records; after processing the valid records using the transformation rules, providing the valid records to a target system; and after providing the valid records to the target system, validating, using the tracers added to the valid records, that the processing of the valid records was properly performed, wherein the validating comprises confirming processing of the first data record based on tracers added to the first data record.
