Data type information (208) associates each of one or more data types with an identifier. Processing data values in fields of records includes: generating data units (203), each including a field identifier and a binary value from one of the records extracted from the field of that record identified by the field identifier; aggregating information about binary values from multiple data units; generating a list of entries for each of one or more of the fields (205), at least some of the entries each including one of the binary values and information about that binary value aggregated from multiple data units; retrieving a data type from the data type information, and associating the retrieved data type with at least one binary value included in an entry; and generating profile information (114) based on a retrieved data type of a particular binary value appearing in a field, after the aggregating. |
