database systems work with relational databases(well structured data) while information retrieval system works on unstructured data (raw text files/documents).
in database systems main datastructure used is relational tables with well define values for each row and column ont the other hand IR system uses Inverted index which is the index of {term,docIDs} entries. for each term there is a corresponding postings list(the list of documents in which the term is present)/
database sytems work on data that are related to each other and have a well defined domain while IR systems may or may not have such a luxury.
