### Data Policy

Data Policy affects processing (parsing) of incorrect or incomplete records. This can be specified by the Data Policy attribute. There are three options:

- Strict. This data policy is set by default. It means that data parsing stops if a record field with an incorrect value or format is read. Next processing is aborted.

- Controlled. This data policy means that every error is logged, but incorrect records are skipped and data parsing continues. Generally, incorrect records with error information are logged into `stdout`. Only ParallelReader, FlatFileReader, JSONReader and SpreadsheetDataReader enable to sent them out through the optional second port. See error metadata description for particular above mentioned readers.

- Lenient. This data policy means that incorrect records are only skipped and data parsing continues.

Data policy can be set in the following Readers:

ComplexDataReader
DBFDataReader
DBInputTable
FlatFileReader
JSONReader
MultiLevelReader
ParallelReader
SpreadsheetDataReader
XMLReader
XMLXPathReader
