System data duplication, or denormalization, causes excess use of redundant storage, excess time processing queries, and possible inconsistency when de-normalized data is changed in one place but not the other. (Any one else have examples? Please enhance this answer. Thank you.)

System data duplication can lead to inconsistencies and errors if not properly managed. It can also increase storage costs and complicate data management processes. Additionally, data duplication can make it challenging to maintain data integrity and can result in difficulties with data synchronization.

Occurs when the same data are stored in many places?
Data duplication occurs when the same data is stored in multiple locations or systems. This can lead to inconsistencies, errors, and challenges in maintaining data integrity. Employing data normalization techniques and centralized storage systems can help reduce data duplication.
Advantages and disadvantages of relational data model?
Advantages of relational data model include data integrity through normalization, flexibility to query data using SQL, and ease of understanding relationships between entities. Disadvantages can include performance issues with complex queries, potential for data duplication across tables, and difficulty in scaling for very large datasets.
Duplication of data can be avoided by?
Implementing a normalized database schema to reduce redundant data. Using unique constraints and primary keys to enforce data integrity. Utilizing foreign keys to establish relationships between tables instead of storing the same data in multiple places.
How data isolation is disadvantage of file system?
Data isolation in a file system can be a disadvantage because it can lead to data duplication, inconsistency, and difficulty in managing data across different applications or users. Each application may have its own data storage system, leading to redundancy and potential synchronization issues. This can also make it challenging to maintain data integrity and security.
What are the disadvantages of using manual information systems?
Disadvantages In Bullet Points:- Time consuming.- Chances of Human error. - Paper work results in need of lot of space to keep the data.- Possibility of data duplication as there's no repetition check like in computer software's e.g Microsoft Access.- Not more then one person can access data at the same time but in Computerized Information system many people can access the same data on the same time through networking.
Is moving data the same as duplicating data?
No, Moving data is not same as duplicating data. When we copy data that causes duplication of data . And while moving we are just changing the storage location of data.To copy data is duplication, but to move data does not cause duplication.
What are the disadvantages of a physical database?

What is a back-up in data storage?
A redundancy or duplication of data.
Disadvantages of file system?
Traditional file processing system lacks from DBMS in many ways . Major Disadvantage of FPS are it do not maintains data security and integrity efficiently.
What are the advantages and disadvantages of file based systems?
File-based systems are low cost and do not need external storage or somebody that is extremely knowledgeable in technology. Disadvantages include data duplication, lack of flexibility, and a lack of security.

What are the disadvantages and advantage of inertial Navigation System?
the disadvantages is it need to give data before flight
What compression technique does data de duplication use?
Data de duplication is a process that eliminates duplicate copies of repeating data. The compression technique that it uses to function is called intelligent data compression.
What is it called when you repeat the same data in many tables in a data base?
duplication
Advantages and Disadvantages of Electronics Data Processing?
Advantages: Economic. Once an Electronic Data Processing system is created and implemented, over time it reduced the costs of managing data by a significant margin. Reduced Labor. Duplication of effort and repeated entries due to mistakes in manual data entry are reduced or eliminated by EDP.
