Read Chapter 6 from the attached pdf and write a discussion topic on How can the key and foreign key constraints be enforced by the DBMS? Is the enforcement technique you suggest difficult to implement? Can the constraint checks be executed in an efficient manner when updates are applied to the database?
Instructions: Response to the question should be 250-300 words. There must be at least one APA formatted reference (and APA in-text citation) to support the thoughts in the post as needed. Do not use direct quotes, rather rephrase the author’s words and continue to use in-text citations.
Requirements: 250-300 words

During deletion processes, an index of the constraints helps reference the record to be deleted. Due to such enforcement elements, this prevents inappropriate deletion of records that could have been useful in the database. This is evident in the update actions, whereby the constraints ensure that the referencing foreign key attributes perform the recommended action efficiently without interfering with other values. Generally, the database designer has to select an appropriate action based on the specified database schema to enhance efficiency.
