Simple data example: Excel file.
Data has a stable structure and there is only one value in the cell. Most database tables and delimited files can be considered simple data. except when a single field has multiple values or holds XML data.
Simple XML file:
XML tags are in the same order, the number of tags is always the same and there are no attributes, This XML does not require any additional transformation and can be easily loaded into the database.
Complex XML message:
The structure is not stable, the number of tags is different for a different customer record, plus it uses attributes. This XML may need some additional transformations.
Complex Text file:
Data is split into different rows, some empty rows should be ignored, some data must be taken from the header
SQL insert script:
