Difference Between Information Retrieval and Data Retrieval
Data Retrieval systems directly retrieve data from database management systems like ODBMS by identifying keywords in the queries provided by users and matching them with the documents in the database. 
Whereas the Information Retrieval system in DBMS is a set of algorithms or programs that involve storing, retrieving, evaluation of document and query representations, esp text-based, to display results based on similarity.

S.No

Information Retrieval

Data Retrieval

1

Retrieves information based on the similarity between the query and the document.

Retrieves data based on the keywords in the query entered by the user.

2

Small errors are tolerated and will likely go unnoticed.

There is no room for errors since it results in complete system failure.

3

It is ambiguous and doesn’t have a defined structure.

It has a defined structure with respect to semantics.

4

Does not provide a solution to the user of the database system.

Provides solutions to the user of the database system.

5

Information Retrieval system produces approximate results

Data Retrieval system produces exact results.

6

Displayed results are sorted by relevance 

Displayed results are not sorted by relevance.

7

The IR model is probabilistic by nature.

The Data Retrieval model is deterministic by nature.
