Data redundancy occurs: A. when shared databases are utilized. Most of the time, data redundancy occurs by accident, but other time is intentional. Data redundancy data is an common issue in computer data storage and database systems. when there is NULL values. Bookmark. Because it is collected and maintained in so many different places, the same data item may have: 1. different meanings in different parts of the organization, Although we are referring to the same Joe in both fields, each piece of data is seen as unique. D. In all properly designed database management systems. Data redundancy occurs. Data redundancy occurs when the same piece of data exists in multiple places, whereas data inconsistency is when the same data exists in different formats in multiple tables. Of course, there are reasons to break this rule and they a. . When inventory has the same data in its files as sales has in its files. 10. 77. Yet, you have multiple sales to the same customer so the same address is entered multiple times. How does data redundancy occur? Data redundancy occurs when the same data is entered in to two or more fields of a database.
When shared databases are utilized. Data redundancy occurs when the same piece of data is stored in two or more separate places. Data Redundancy Explained. Most of the time, data redundancy occurs by accident, but other time is intentional. Data redundancy sometimes occurs by mistake, and others are deliberate. Data redundancy can be found in a database, which is an organized collection of structured data that's stored by a computer system or the cloud.
Data redundancy occurs when the same piece of data is stored in two or more separate places and is a common occurrence. Data redundancy occurs when different divisions, functional areas, and groups in an organization independently collect the same piece of information.
The Problem of redundancy in Database. C. when customer addresses are needed by both shipping and billing. Data redundancy sometimes occurs by mistake, and others are deliberate. Whereas, data inconsistency is a condition that occurs between tables when we keep similar data in different formats in two different tables, or when matching of data .
Suppose a table of student details attributes are: student Id, student name, college name, college rank, course opted. If you do, you are wasting space and perhaps more importantly, you now have the risk that they will get out of sync. B.
By controlling the data redundancy, the data consistency is obtained. When shared databases are utilized. Definition.
This problem arises when a database is not normalized. Suppose a table of student details attributes are: student Id, student name, college name, college rank, course opted. Answer: Data redundancy occurs when different divisions, functional areas, and groups in an organization independently collect the same piece of information. Data redundancy occurs when the same data point is multiplied across the database and can be found repeated in an unnecessary form. This data repetition may occur either if a field is repeated in two or more tables or if the field is repeated within the table. (5 marks) Data redundancy occurs in database systems which have a field that is repeated in two or more tables. This differs from data duplication, as it is often not intentional and can take up potentially required storage space. For instance, when customer data are duplicated and attached with each product bought, then redundancy of data is a known source of inconsistency since customer might appear with different values for given attribute. For instance, when customer data are duplicated and attached with each product bought, then redundancy of data is a known source of inconsistency since customer might appear with different values for given attribute. 1). C. When customer addresses are needed by both shipping and billing. That's why one major goal of good database design is to eliminate data redundancy. Because it is collected and maintained in so many different places, the same data item may have: 1. different meanings in different parts of the organization, This is why we normalize databases. 10.

The two are: Wasteful data redundancy: Wasteful data redundancy occurs when the data doesn't have to be repeated but it is duplicated due to inefficient coding or process complexity. For the users, it becomes easy to recover the data after it damages or lost. Data redundancy: a. occurs when data is stored in multiple locations b. is eliminated by using the applications approach c. reduces labor and storage costs d. improves consistency between applications ANS: A PTS: 1. Users are doing different inefficient coding or complex process while intentional data redundancy is produced due to data protection and consistency surety. Data can appear multiple times in a database . It may not seem like a big deal until multiple data sets pile up more than once, taking up gigabytes of storage space on your servers. For example, having a customer address on multiple systems makes sure you can verify one against the others whenever there is a question. D. In all properly designed database management systems. When customer data is duplicated and attached with each product bought, then redundancy of data is a known source of inconsistency, since the entity "customer" might appear with different values for a given attribute.
C. When customer addresses are needed by both shipping and billing. Yet, you have multiple sales to the same customer so the same address is entered multiple times. Wasteful data redundancy generally occurs when a given piece of data does not need to be repeated but ends up being duplicated due to inefficient coding or process complexity.
