What does Data Redundancy mean in database design?
In database there are number of issues to be handled ,like redundant data, inconsistent data, unorganized data etc. Redundancy of data is the repetitive data that is taking the storage unnecessarily . So the redundant data must be removed or at least reduced.
What are the strength of the database?
Reduced data redundancy, Improved data integrity, Shared data, Easier access, Reduced development time
Data redundancy produces what?
Data redundancy produces unnecessary duplication of data within a database or system, which can lead to increased storage costs and potential inconsistencies. When the same data exists in multiple locations, it can create challenges in maintaining data integrity and accuracy. Additionally, redundant data can complicate data management and retrieval processes, making it harder to ensure that users access the most current and reliable information.
Is data redundancy leads to data inconsistency?
yes. data redundancy is where there is duplication of data in a database. when this happens, anyone who has to make updates to a table in a database (that is, make changes to the database) will have to change that particular data that has been duplicated so many times in so many places. this creates a problem and it is not always going to be possible for a person to change everything correctly. this therefore leads to inconsistencies in the database. hope this helps.
Disadvantages of data redundancy?
Data redundancy can lead to storage inefficiency, as the same information is stored multiple times. It can also increase the risk of inconsistencies or errors in the data, as updates may not be made consistently across all duplicates. Additionally, data redundancy can make data management and maintenance more complex and time-consuming.
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?
coding redundancy interpixel redundancy psycovisual redundancy
What is difference between the data validation and data redundancy?

What is data redundacy?
Data redundancy means storage of data.
What is Data redundancy in DBMS?
In database we store data however the can be redundant. Redundancy means repetitive data that is taking extra storage space . So to reduce or prevent the storage space we should eliminate redundancy or just reduce it.
What does data redundancy mean?
Data redundancy: Sometime Data redundancy refers to in computer data storage, is a property of some disk arrays which provides fault tolerance, so that all or part of the data stored in the array can be recovered in the case of disk failure. The cost typically associated with providing this feature is a reduction of disk capacity available to the user, since the implementations require either a duplication of the entire data set, or an error-correcting code to be stored on the array.Redundancy is attained when the same data values are stored more than once in a table, or when the same values are stored in more than one table.One of the biggest disadvantages of data redundancy is that it increases the size of the database unnecessarily.
What is an example of data redundancy?
An example of data redundancy is when the same information is stored in multiple places in a database. For example, if customer addresses are stored in both an "order details" table and a "customer information" table, it creates redundancy. This redundancy can lead to inconsistencies if the data is not properly maintained.
Disadvantages of relational database model?
Lack of scalability: Relational databases can struggle with scalability as the data grows in size and complexity. Performance issues: Join operations and complex queries can lead to slower performance in relational databases. Data redundancy: Normalization in relational databases can result in storing data in multiple tables, leading to redundancy and inefficiency.
