SQL Server Foreign Key Update and Delete Rules

Foreign key constraints are an integral part of SQL Server database design. These are used to maintain integrity among related data in different tables. While implementing update and delete operations on values in the parent table (referenced table with primary key) we have to consider the impact on related values in the child table. SQL Server provides different rules for managing the effect of updates and deletes on child table values. How can these rules be used effectively without threatening the relational integrity?
