Final answer:
To reduce the amount of visible data in a database, Annemarie should apply filtering, which allows setting specific criteria to display only relevant records. Sorting and grouping organize the data but don’t reduce its amount, and deleting permanently removes data.
Step-by-step explanation:
To reduce the amount of data that is visible within a database, Annemarie can apply filtering. Filtering allows her to specify criteria for the data she wants to view, therefore reducing the amount of data displayed. For example, if she only wants to see records where the value in a certain field is greater than 50, she can set up a filter for this condition, and only these records will appear.
Sorting, on the other hand, would only rearrange the data based on alphabetical or numerical order and wouldn't reduce the amount of data visible but could help her in finding data quicker. While grouping might make the data more organized by categorizing it into groups, it does not necessarily reduce the visible data itself. Deleting would permanently remove data, which likely isn't advisable unless she's sure that the data is no longer needed.
To answer the questions:
-
- The correctness of tables isn't in question here since we are discussing data visibility rather than accuracy or efficiency in data representation.
-
- Grouping data could be based on different attributes or categories, depending on Annemarie's needs. Grouping could provide a clearer overview of distinct segments of the data, but filtering is what actually reduces visibility of non-relevant data.
-
- The question did not imply we switched between tables, but rather between methods of managing data visibility.
