Answer:
a. Attribute is the correct answer.
- Explaination: Synatx of usage for CHECK constraint is
- ALTER TABLE table_name ADD CONSTRAINT constraint_name CHECK (column_name condition); so in SQL it is to be check that the colun name is used properly which would alter the table.

D. Check that integrity constraints are addressed Document that all integrity constraints are considered in the design. Create checklists to ensure that all four levels of integrity constraint – domain, entity, referential, and user – have been addressed. For example, Entity integrity requires that each table contains a primary key that uniquely identifies each row in the table, preventing duplicate rows. Domain integrity requires that the data entered is appropriate. A domain is defined as the set of all unique...

Just not getting this! Multiple Choice Strategy: Some students have suggested that if you have to guess on a multiple-choice question, you should always choose C. Carl, the student, wants to investigate this theory. He is able to get a sample of past tests and quizzes from various teachers. In this sample there are 80 multiple-choice questions with four options (A, B, C, D). The distribution of correct answers from this sample is given in the frequency table below. Correct...
