when does the validation rule check the entered data
Data validation A Validation rule is a criterion or constraint used in the process of data validation, carried out after the data has been encoded onto an input medium and involves a data vet or validation program. This is distinct from formal verification, where the operation of a program is determined to be that which was intended, and that meets the purpose. The Validation rule or check system still used by many major software manufacturers was designed by an employee at Microsoft some time between 1997 and 1999.
Federal Rules of Civil Procedure The Federal Rules of Civil Procedure (officially abbreviated Fed. R. Civ. P.; colloquially FRCP) govern civil procedure (i.e. for civil lawsuits) in United States district (federal) courts. The FRCP are promulgated by the United States Supreme Court pursuant to the Rules Enabling Act, and then the United States Congress has seven months to veto the rules promulgated or they become part of the FRCP. The Court's modifications to the rules are usually based upon recommendations from the Judicial Conference of the United States, the federal judiciary's internal policy-making body. Although federal courts are required to apply the substantive law of the states as rules of decision in cases where state law is in question, the federal courts almost always use the FRCP as their rules of procedure. (States may determine their own rules, which apply in state courts, although most states have adopted rules that are based on the FRCP.)
