Which of the following anomalies result from a transitive dependency
Correct answer: D. All of them
- A. Insertion
- B. Modification
- C. Deletion of an entity cash attribute must have
- D. All of them
Explanation
A transitive dependency occurs in a database table when the value of one attribute indirectly determines the value of another attribute, through a chain of relationships involving two or more other attributes. This redundancy can lead to several data anomalies, which are inconsistencies in the data that can cause problems. By eliminating transitive dependencies and following the principles of database normalization, you can reduce or eliminate these anomalies and improve the integrity and consistency of your data

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
