To facilitate query specification 10. (5Answer the following questions: a)  Why should we avoid creating calculated data fields in a table? b) Why should we store data in their smallest parts? c) Why should we establish validation rules for data fields? d) Why should we use multiple tables, instead of a global table? e) What does it mean by the property “required”? Answer: To save space To facilitate query specification To keep data consistency, preventing the user from entering wrong data To save space. Normally, in a global table, much redundant data will be stored. For each record, a concrete value for the corresponding data field must be provided. May 2018 ACS-2814 Yangjun Chen
