Insert

 

The Insert operation creates a new row in a table.

 

Well that's almost true. What really happens is a temporary space is created where you can input the values for a new row. When your done, the new values are submitted to the database and the new row is created.

 

Delete

 

The Delete operation is used to remove one or more rows from a table. In most cases, when a row has been deleted it cannot be restored.

 

Edit

 

The Edit operation allows changes to be made to an existing row.
