Ajax| Menu | dropdown The cascading drop-down menu is when you select an item from a Drop-down menu, and the contents of the corresponding Drop-down menu change. In general, the simplest is to submit a form every time you select it, refreshing the entire page. This is also the worst user experience. The other is to load all the options into a JavaScript array in the entire page at the first load, then cascade through JavaScript, which is a nice way to

Constraints can also be used to establish referential integrity between tables in a database. Having referential integrity means that the data is consistent and non-destructive. For example, if a customer's record is deleted but the customer's waybill record still exists in the database, then the data is not consistent, that is, there is an isolated customer waybill record in the database. Referential integrity is established when a user establishes a relationship between the various tables. In
