Storing the information several time leads to waste of storage space is called data redundacy.
Data redundancy is a term used about databases and means simply that some data fields appear more than once in the database. Data redundancy is wasteful and inefficient for several reasons and database designers attempt to eliminate it as far as possible by using a technique called data normalization.
Data redundancy occurs in database systems which have a field that is repeated in two or more tables. For instance, in case when customer data is duplicated and attached with each product bought then redundancy of data is a known source of inconsistency.

Data redundancy refers to the unnecessary duplication of data in a database or system. It can cause inefficiencies, make updates more difficult, and increase storage requirements. Data redundancy can be minimized through normalization techniques in database design.

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.
What is data redundancy and which characteristics of the file system can lead to it?
Data redundancy refers to repetitive data in the database. In a system with redundant data it is difficult to manage the relationships. Data redundancy is the result of poorly designed database. By implying proper constraints on the data it can be prevented.
How is data redundancy reduced?
Data redundancy can be reduced by normalizing the database to eliminate duplicate data, creating relationships between tables, and using foreign keys to link related information. Using data validation rules and constraints can also help prevent redundant data from being entered into the database. Implementing a master data management strategy can centralize and standardize data, reducing redundancy across different systems.
Advantage of Data redundancy?
One advantage of data redundancy is increased data availability and fault tolerance. By storing the same data in multiple locations, the system can continue to function even if one copy of the data is lost or corrupted. Data redundancy also helps improve data retrieval speeds by allowing data to be accessed from multiple sources simultaneously.
Redundancy control in databases?
Redundancy control in databases involves minimizing duplicate data storage to improve efficiency and reduce potential inconsistencies. Techniques such as normalization, using primary keys, and enforcing constraints like unique constraints help prevent redundancy by structuring and managing data effectively. Eliminating redundancy can enhance data integrity, improve query performance, and simplify data maintenance in database systems.
How can a primary key be useful in controlling data redundancy?
controlling data redundancy
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.
What are a couple of problems whit a traditional file environment?
Data redundancy Lack of data redundancy Data inconsistency Data security
What is data redundancy and problems associated with it?
Duplication of data is data redundancy. It leads to the problems like wastage of space and data inconsistency.
What are three types of redundancy checks used in data communications?
