When should Query Generators be used?
- Any time you want to query real data from within a specified file or database.
Why are Query Generators useful?
- Query Generators make it easy to blend real data values with synthetically generated data. For example, combining real postal addresses with synthetically generated names.
- Query Generators make it easy to create a subset of real production data.
