You are considering creating a Many-to-Many relationship between two Dataverse tables. One of the critical limitations of this relationship type is that you cannot edit the tables. 
What are two alternatives that can help to avoid this limitation and relate the tables?

Answer options:

A.Create a One-to-Many relationship between two tables
B.Create a new table with two One-to-Many relationships
C.Create a Many-to-One relationship between two tables
D.Create connections between two tables
E.Create a One-to-One relationship between two tables

Correct Answers: B and D 
Dataverse identifies two types of relationships between tables: One-to-Many (1:N) and Many-to-Many (N:N). 
A One-to-Many relationship is between a record in a primary (or parent) table and many records in the related (or child) table. This relationship type is also called the Parent-Child. A good example of this type is a relationship between a customer and the orders: each customer can have multiple orders. 
A Many-to-Many relationship is when multiple records from one table have relationships with the multiple records in another table and vice versa. An example of this type is a relationship between students and classes: each student enrolls in multiple classes, and each class has multiple students enrolled. 
When users create a Many-to-Many relationship, the Dataverse creates a specific hidden intersect matching table between the records in two tables. After you create a N:N relationship, you cannot edit both tables. 
You can avoid this limitation by creating a new custom table and establish two One-to-Many relationships between a new table and each of the other tables. By introducing the third table, you will avoid the limitation mentioned above. 
Another possible solution is connections. Connections are a particular case for the Many-to-Many relationships. They are flexible and don`t have the limitations of the N:N relationship. 
All other options are incorrect.
