The difference of function between DBMS and IRS is shown at table below:-

DATABASE MANAGEMENT SYSTEM (DBMS) INFORMATION RETRIEVAL SYSTEM (IRS)
Data Security With this function, the DBMS able to secure the user security and data privacy within the database by determine the user access right – prevent unauthorized user from access and update the database, for example, by using password, only the authorized user allowed to access the database or update the database. > A range of entities that stored within the database are attach with access control list which usually specify the group of user that can access and update the entities.
> An appropriate security control needed so that when user access and sharing the database with the data at different sensitivity level without violating the security.
Data Integrity This function is reducing the problem of data integrity such as minimize the data redundancy – same data are stored in more than one place within the database without purpose, and maximize the consistency of data – make sure that the user are retrieve the correct/same data or answer when the same question/task being ask.
The DBMS can also ensure that only one user can update the data at one time. > With this function, IRS able to analyze the queries from user and then characterize the item in the form that matching the database.
