Data inconsistency exists when different and conflicting versions of the
same data appear in different places. Data inconsistency creates
unreliable information, because it will be difficult to determine which
version of the information is correct. (It's difficult to make correct - and
timely - decisions if those decisions are based on conflicting information.)
Data inconsistency is likely to occur when there is data redundancy. Data
redundancy occurs when the data file/database file contains redundant -
unnecessarily duplicated - data. That's why one major goal of good
database design is to eliminate data redundancy.

What are the limitations of flat file databases?
• Data duplication• Data inconsistency or update/deletion/insertion anomalies• Data integrity errors (due to data inconsistency)• Inconsistent search results in multi-value fields
The problem of inconsistency in data is a direct result of?
The problem of inconsistency in data can arise from various factors such as errors in data entry, lack of standardized data formatting, and incomplete data updates. Inconsistent data can lead to inaccurate analysis and decision-making, affecting the overall reliability of data-driven processes.
What is redundancy and inconsistency in data base management system?
Redundancy in a database occurs when the same piece of data is unnecessarily stored in multiple places, leading to inefficiency and potential data inconsistencies. Inconsistency arises when different copies of the same data do not match due to errors or failure to update all instances simultaneously, impacting data integrity and reliability. Database management systems aim to reduce redundancy and ensure consistency through normalization and transaction processing techniques.
When data change in multiple list and all list are not updated then it called?
Data inconsistency
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 is the definition of data inconsistency?
Data inconsistency refers to discrepancies or contradictions in data within a system or across different systems. This can occur when the same data is stored in multiple locations and gets updated independently, leading to discrepancies in the information. Data inconsistency can impact data integrity and can cause errors in reporting and decision-making.
What is Drawbacks of using file system to store data?
* Data redundancy and inconsistency. * Data isolation * Problem in atomicity of data * Difficulty to access data. * Security Problems
Advantage of an Oracle Database system?
Advantages provided by a database system are : a) Redundancy of data is reduced. b) Secured data. c) Controlled data inconsistency. d) Integrated data. e) Standardized data
What is data integration?
To integrate has two separate meanings. It might mean simply that different sets of data are put together. It can also refer to a mathematical process which is part of the calculus.
What is meant by data inconsistency in DBMS?
It Occures When The Same data Dosent Matches Each Other In Various Relations(Tables) take an exp of this,suppose a publisher request for change his address is stored in a book as well as , if address of publisher is not modified in any of two field than the same publisher will have diff. address into diff. field .This is known as data inconsistency
What is the plural form of inconsistency?
