Whenever reporting groups occur, the reporting attribute must be removed and placed
Correct answer: C. Where it belongs
- A. Only one
- B. Where it don't belong
- C. Where it belongs
- D. When it originates
Explanation
Where it belongs is the most likely answer. This refers to the process of data normalization in relational databases. When encountering reporting groups (repeating data within a table), the reporting attribute (the attribute that identifies the group) needs to be moved to a separate table along with a foreign key that references the original table. This eliminates data redundancy and improves data integrity

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.
