A method comprising: receiving, by computing hardware, a request to identify targeted data for a data subj ect; identifying, by the computing hardware, a first data object from a plurality of data objects using metadata for a data source, wherein the metadata identifies the first data object as associated with a first targeted data type for a data portion from the request; identifying, by the computing hardware, a first data field from a first graph data structure having a) first nodes representing the first data object, the first data field, and the first targeted data type and b) first edges connecting the first nodes, wherein the first graph data structure identifies the first data field as used for storing data having the first targeted data type; querying, by the computing hardware, the first data object based on the first data field and the data for the first targeted data type to identify a first targeted data portion for the data subject; determining, by the computing hardware, the first targeted data portion is associated with a second targeted data type; identifying, by the computing hardware, a second data object from the plurality of data objects using the metadata for the data source, wherein the metadata identifies the second data object as associated with the second targeted data type; identifying, by the computing hardware, a second data field from a second graph data structure having a) second nodes representing the second data object, the second data field, and a second targeted data type and b) second edges connecting the second nodes, wherein the second graph data structure identifies the second data field as used for storing data in the second data object having the second targeted data type; querying, by the computing hardware, the second data object based on the second data field and the first targeted data portion associated with the second targeted data type to identify a second targeted data portion for the data subject; and performing a targeted data action based on the first targeted data portion or the second targeted data portion, wherein the targeted data action comprises at least one of generating a location map for the targeted data that comprises a storage location for each of the first targeted data portion and the second targeted data portion, providing the first targeted data portion and the second targeted data portion for display on a graphical user interface to a user who submitted the request for the targeted data, or removing the first targeted data portion and the second targeted data portion from the data source. receiving, by computing hardware, a request to identify targeted data for a data subj ect;
