When two tables share the same primary key, they share a
A. one-to-one relationship.
Explanation:
- One-to-one relationship is a type of cardinality that refers to the relationship between two entities A and B in which one element of A may only be linked to one element of B, or the opposite way.
- A one-to-one relationship in a relational database occurs when one parent record or field has either zero or one child record only.
- These relationships are the easiest to represent in databases because both the parent and child records may be in the same table.
- One-to-one relationships associate one record in one table with a single record in the other table.
- These relationships are frequently used to indicate critical relationships so you can get the data you need to run your business.
- A one-to-one relationship is a link between the information in two tables, where each record in each table only appears once.
Answer:
A. A binary search can only be used on an ordered group of data values.
Explanation:
Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements.
Binary search applies the principles of divide and conquer.
In Computer programming, performing a binary search on an array requires that the array should be sorted in an ascending order i.e from the least to the highest with respect to the data value.
Hence, the true statement is that a binary search can only be used on an ordered (sorted) group of data values.
