When two tables share the same primary key, they can be related through one-to-one, one-to-many, or many-to-many relationships, each serving a specific data structuring purpose in a database.
When two tables share the same primary key, there are several types of relationships that can exist between them. The most common types are one-to-one, one-to-many, and many-to-many relationships.
A one-to-one relationship exists when a row in table A can have only one matching row in table B, and vice versa, such as a person's social security number and their tax record.
The one-to-many relationship occurs when a row in table A can have many matching rows in table B, but a row in table B can have only one matching row in table A. This is the most common relationship found in databases. For example, a customer can have many orders, but each order is placed by one unique customer.
Lastly, the many-to-many relationship exists when a row in table A can have many matching rows in table B, and vice versa. This relationship typically involves a junction table to manage the associations, such as students enrolling in various courses and courses containing various students.
These relationships are crucial for determining how to structure tables within a database to avoid redundancy and ensure efficient data organization.
When two tables share the same primary key, they have a one-to-one relationship(option B)
This means that each row in the first table corresponds to exactly one row in the second table, and vice versa.For example, consider a database where each person has only one passport number, and each passport number is assigned to only one person. Here, both the person and the passport tables would share the same primary key to represent this relationship clearly.Other relationships like one-to-many, many-to-one, or many-to-many would require one or more foreign keys or intermediate tables, and sharing the same primary key would not apply to these scenarios.
Hence,option B is correct
Complete Question:
Which relationship is possible when two tables share the same primary key?
A.one-to-one
B.one-to-many
C.many-to-one
D.many-to-many

A.lets you select part of an image by drawing a polygon
B.lets you select part of an image by drawing freehand
C.lets you select similar shaded areas in an image
D.lets you select part of an image by automatically tracing outlines
Final answer:
The Magnetic Lasso tool allows for accurate image selection by automatically adhering to and tracing the edges of objects, similar to how magnetic field lines define the shape of magnetic fields.
Explanation:
The property of the Magnetic Lasso tool is that it lets you select part of an image by automatically tracing the outlines. This feature is particularly useful in graphic editing software such as Adobe Photoshop. Similar to how magnetic field lines are used to represent magnetic fields, the Magnetic Lasso tool uses the concept of a "magnetic" attraction to edges within an image to allow for precision in selecting objects. As you click and drag the tool around the edge of an object, it clings to the pixel contrasts that define an edge. The tool is adept at finding and snapping to the exact border between elements in the image.
Magnetic field properties, such as being tangent to the field line, the proportionality of field strength to line density, and the fact that lines do not cross and are continuous loops, though unrelated to the Magnetic Lasso, share the concept of defining boundaries and applying rules for visual representations. These properties, when taken into account in physics, provide a framework for understanding magnetic forces and interactions.

Select the answer that best describes what an opportunity cost is?
A. The amount of money you put into your savings each year.
B. The trade-off of making one choice and giving up a different choice.
C.The benefit you gain by choosing one option versus another.
D. The amount of money a business makes every year from sales.
Answer:
B. The trade-off of making one choice and giving up a different choice.
Explanation:
Opportunity cost is the worth of the option forgone. It is also called the alternative forgone or real cost. It is a concept that arises as a result of the unlimited wants that cannot be satisfied with the limited resources available.
For example, a man who has $1 million dollars can but a home for $900,000 which makes it impossible for him to buy a car of $500,000 because he has just $1 million. The cost of the car that was not purchased is the opportunity cost in this.
Hence the right option is B. The trade-off of making one choice and giving up a different choice.

Discussing hobbies and leisure activities can uncover how individuals identify with certain groups or communities. With the transition to college life, this also includes understanding the new language uses one might develop, to communicate and engage effectively in an academic environment.
I plan to use my earnings from the UC application for educational purposes, such as covering tuition fees, purchasing textbooks, and investing in additional learning resources.
Explanation:The earnings generated from the UC application hold significant value in supporting my educational journey. With the rising costs of higher education, these funds will play a pivotal role in covering tuition fees. For instance, if the earnings amount to _$X_, and my annual tuition cost is _$Y_, I can allocate a portion or potentially the entirety of the earnings to offset this expense, relieving financial burdens and allowing me to focus on academics.
