You can access data in NDAD either by browsing rows in the table sequentially, or by using queries. Queries allow you to subset, or
filter, the data so that you only see what you want to see. Most tests are based on simple elements, and you can build up complex
queries either by joining simple tests together, or by writing an Advanced Query.
When browsing or querying data, you can choose to view only certain columns in a table, and you can decide how many rows are displayed
at once. More rows take longer to download, and your browser will take longer to format the data.
