Field attributes are attributes that provide additional information about each field that you can use in pipeline logic, as needed.

Fixed length means having a set length that never varies. In database systems, a field can have a fixed or a variable length. A variable-length field is one whose length can be different in each record, depending on what data is stored in the field.key field - Computer Definition. A field in a record that holds unique data which identifies that record from all the other records in the file or database. Account number, product code and customer name are typical key fields.
