1. A method of data processing in a data processing system including a processor, the method comprising:
the processor recording, in a lineage repository, dependence relationships between data objects;
the processor recording, in a classification repository, data classifications applicable to data objects, wherein the data classifications each indicate a respective class of sensitive data to which data protection is to be applied;
a processor, based on receiving a classification job requesting classification of a first data object, determines whether the lineage repository records a dependence relationship with a second data object;
based on determining that the lineage repository records a dependence relationship with the second data object, the processor associating in the classification repository at least a particular data classification applicable to the second data object with the first data object; and
the processor applying data protection applicable to the particular data classification to the first data object.
