System redundancy refers to the inclusion of additional components or systems that serve as backups to ensure continuous operation and reliability in case of a failure. This can involve duplicating hardware, software, or network resources to prevent downtime and maintain service availability. By implementing redundancy, organizations can enhance fault tolerance and improve overall system resilience against unexpected disruptions.
DBS has more security and data integrity.It reduce data redundancy and updating errors which can occur in FBS.Contains of concurrent data access.But also it's expensive to use and they are also complex.Damage to DB affects virtually all application programs.
Some limitation of file processing include:1. Data redundancy and inconsistency2. Difficulty in accessing data3. challenges with data security4. Often, time consuming and tedious
In non-database systems each application has its own private files. This can often lead to redundancy in stored data, with resultant waste in storage space. In a database the data is integrated. The database may be thought of as a unification of several otherwise distinct data files, with any redundancy among those files partially or wholly eliminated. Data integration is generally regarded as an important characteristic of a database. The avoidance of redundancy should be an aim, however, the vigour with which this aim should be pursued is open to question. Redundancy is * direct if a value is a copy of another * indirect if the value can be derived from other values: ** simplifies retrieval but complicates update ** conversely integration makes retrieval slow and updates easier * Data redundancy can lead to inconsistency in the database unless controlled. * the system should be aware of any data duplication - the system is responsible for ensuring updates are carried out correctly. * a DB with uncontrolled redundancy can be in an inconsistent state - it can supply incorrect or conflicting information * a given fact represented by a single entry cannot result in inconsistency - few systems are capable of propagating updates i.e. most systems do not support controlled redundancy.
A cyclic redundancy check error or CRC error occurs when the data verification value is a redundancy. This is used in detecting common errors caused by noise in transmission channels.
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.
I was looking for the answer to that myself, then I recalled something about redundancy, I think maybe dual redundancy, or something along that line.
Controlled redundancy refers to intentionally duplicating certain components in a system to ensure reliability and fault tolerance, whereas uncontrolled redundancy occurs unintentionally due to inefficient processes or lack of coordination. Controlled redundancy is planned and managed to enhance system performance, while uncontrolled redundancy can lead to inefficiencies and waste of resources.
Redundancy refers to the inclusion of extra components to ensure system reliability, while duplication involves creating an exact copy of something. Redundancy can help prevent system failure by providing backup options, while duplication involves replicating data or information for various purposes.
There is a school of thought residing with how much redundancy should be built in. obviously more redundancy should make it more reliable however those same additional parts could make the system fail as a consequence of additional redundancy.
Redundancy, that's where everything is duplicated. Redundancy, that's where everything is duplicated. Depending on the application, you may even want fault tolerance, in which the system AUTOMATICALLY fails over to the backup system.
Redundancy is important in data storage and system design to ensure data reliability and availability. By having redundant systems and backups in place, the risk of data loss due to hardware failures or other issues is minimized. Redundancy also helps in maintaining system performance and continuity in case of failures, ultimately enhancing the overall reliability of the system.
DBMS stands for database management system. DBMS reduce data redundancy as it checks if the data is duplicate and if duplicate then store it as a single record.

The four types of redundancy in linguistics are syntactic redundancy, lexical redundancy, morphological redundancy, and phonological redundancy. These redundancies help convey meaning, aid in communication, and ensure clarity in language use.
