Question 12
Justify the use of the following database features: - Wildcard - Grouping
Step 1
Answer
A wildcard is used to do advanced searches in a database. It acts as a placeholder representing one or more characters in search criteria. For example, the use of '' can help in searching for all records beginning with a certain letter, such as 'c', which will return any record starting with 'c'. Additionally, a wildcard can be useful for finding records that contain a specific word; for instance, using 'fine*' will return any record that includes 'fine' as part of a longer word like 'finished' or 'finer'.
Step 2
Answer
Grouping allows data to be organized in a manner that is easier to read and understand at a glance. It enables information to be displayed with similar data, reducing the clutter of repetitive fields by consolidating them under one heading. This not only enhances clarity but also facilitates easier data retrieval and sub-totalling for analysis, making the overall data presentation more efficient.
