respond to of the following questions: Referential integrity “rules” trigger some cleanup of your data when insertion, update, or deletion events would typically cause data anomalies. But the word “trigger” has its own place in database design and implementation. Research the concept of a “trigger” and compare and contrast “trigger” events with referential integrity rules. Discuss the concept

Hello Class! Please respond to of the following questions: Referential integrity “rules” trigger some cleanup of your data when insertion, update, or deletion events would typically cause data anomalies. But the word “trigger” has its own place in database design and implementation. Research the concept of a “trigger” and compare and contrast “trigger” events with referential integrity rules. Discuss the concept of the intersection table. Why is it needed in many to many relationsps? Why is intersection data needed? PART 2 Peer Responces Respond to both peers discusion posts Peer #1 Bill Triggers are somewhat like a procedure is in computer languages such as a Java or JavaScript. Triggers are able to perform a few different functions whenever the operation is called; Insert, Update, Delete, Create, Alter, or perform events such as logon and off or startup and shutdown. Trigger events assist tables with referential integrity by maintaining their orphaned records. That is, inserting a cld record when no parent record exists; deleting a parent record, and leave the cld record alone; and changing a parent’s record’s pk value so that the fk no longer point to a valid parent record. An intersection table provides an intersection between two components and is a table that defines many-to-many relationsps. The intersection table is also created as another table to eliminate many-to-many relationsps of two tables. The table contains two foreign keys that defines the many-to-many relationsp between two separate tables. Peer #2 John
