A Database Management System (DBMS) ensures data integrity and consistency through several mechanisms:

1. **Data Validation Rules**: DBMS has built-in validation rules that can be applied to ensure the data entered into the database is correct and consistent. For example, a field that is supposed to contain a date will reject any data that doesn't fit the date format.

2. **Transactions**: A transaction is a single logical unit of work that accesses and possibly modifies the contents of a database. Transactions in a DBMS maintain integrity by ensuring that any operations that are performed on the database will bring it from one consistent state to another. This is done by ensuring that any transaction is Atomic, Consistent, Isolated, and Durable (ACID).

3. **Concurrency Control**: DBMS uses concurrency control to ensure that multiple users can access the database simultaneously without affecting the integrity and consistency of the data. This is done through locking mechanisms, where a user is given exclusive access to a part of the database until their transaction is complete.

4. **Data Redundancy Control**: DBMS reduces data redundancy by ensuring that each piece of data is stored in only one place in the database. This helps maintain consistency as there is only one copy of the data that needs to be updated.

5. **Backup and Recovery**: DBMS has built-in backup and recovery tools that can be used to recover data in case of a failure. This ensures that the data remains consistent even after a system failure.

6. **Security Measures**: DBMS also uses various security measures like authentication and authorization to prevent unauthorized access and modification of data, which helps in maintaining data integrity and consistency.
