What is the difference between file base system and data base system?
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.
What is the limitation of File processing system?
Some limitation of file processing include:1. Data redundancy and inconsistency2. Difficulty in accessing data3. challenges with data security4. Often, time consuming and tedious
What is Controlled redundancy in a database?
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.
Cyclic redundancy check error?
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.
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 is it called when you have a system then a system in case the first system fails?
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.
What is an example of fail safe principle of redundancy?
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.
How can hardware be risk free?
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.
How does DBMS reduce data redundancy?
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.
What are three types of redundancy checks used in data communications?
coding redundancy interpixel redundancy psycovisual redundancy
What are the two major weaknesses of file processing system?
data redundancy and data isolation
The purpose of communications system redundancy is to?
Is to ensure that communications can be maintained if primary systems fail.
What is the difference between file base system and data base system?
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.
What is redundancy-?
Redundancy is the excessive repetition of something. A common example used by teachers/comic strip writers is the "Redundant Department of Redundancy" In the field of computers or electronics redundancy refers to having multiple components with the same function so that one or more can fail and the entire system can continue to function.
When was The Redundancy of Courage created?
The Redundancy of Courage was created in 1991.
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.
