1. Wasted Storage Space.
2. More difficult Database Updates.
3. A Possibility of Inconsistent data.
Note: A solution to the problem is to place the redundant data in a separate table, one in which the data no longer will be redundant.

DO you have redundancy of records in distributed DBMS?
Redundancy means duplicacy of data or repetitive data. In distributed database case the data is stored in different systems . So the answers is yes there can be redundancy of records / data.In distributed database , data is stored in different systems. Since the data is distributed there is redundancy of records.

Data redundancy means storage of data.
What is Data redundancy in DBMS?
Data redundancy in DBMS refers to the duplication of data within a database system. This can result in inconsistencies and inefficiencies, as well as consuming more storage space. It is important to minimize data redundancy in order to maintain data integrity and improve performance.
