Reports are used to show information from the tables or queries in a printable form. 


Que 3 Explain the design grid of the Query window.

Ans - The Query window is divided into two panes. The top pane displays the tables selected for the query. The bottom pane displays options to add fields and specify the criteria. It has following options:

Que 4. What is the difference between AND condition and OR condition ?

Ans - When we type two criteria on the same line, only records where both criteria are met will be displayed when we run the query. This is called AND condition. When we type one criteria on the Criteria row and the second criteria on the Or row, the records where either criteria are met will be displayed as output. This is called OR condition.
