trigger AccountTrigger on Account (before insert, before update) {
AccountTriggerDispatcher.dispatch(Trigger.operationType);

public class AccountTriggerDispatcher {
public Static void dispatch(System.TriggerOperation operationType){

AccountTriggerHelper.helperBeforeInsertUpdate(accountList);
}
public Static void beforeUpdate(ListaccountList){
