Master-Detail Relationship (1:n):-
It is a figure-baby dating wherein the grasp object controls the conduct of the dependent toddler object. It is a 1:n relationship, wherein there may be most effective one figure, but many children.
The important concept you want to be realize is that, being the controlling item, the master subject cannot be empty. If a document/ field in grasp object is deleted, the corresponding fields in the dependent item are also deleted. This is called a cascade delete. Dependent fields will inherit the owner, sharing and security settings from its master.
You can outline grasp-detail relationships among custom objects, or among a custom object and preferred item as long as the usual item is the master in the relationship.
Lookup Relationship (1:n):-
Lookup relationships are used while you want to create a hyperlink among two gadgets, but without the dependency on the determine item. Similar to Master-Detail courting, you could think about this as a shape of parent-child relationship wherein there is only one discern, however many children i.E. 1:n dating.

Junction Relationship (Many-To-Many):-
This type of a courting can exist whilst there's a need to create two master-element relationships. Two master-detail relationships can be created by way of linking 3 custom items. Here, two objects can be grasp gadgets and the 1/3 item may be depending on each the items. In less complicated phrases, it is going to be a child object for both the master objects.
Q14. What happens to detail document while a master record is deleted? What occurs to infant record while a figure record is deleted?

In a Lookup courting, even though the determine report is deleted, the child report will not be deleted.
Q15. Can you've got a roll up precis discipline in case of Master-Detail relationship?
Ans: Yes. You could have a roll-up precis in case of a grasp-detail relationship. But not in case of a research relationship.

There are 4 calculations that you could do using roll-up summary subject. You can rely the variety of detail information related to a master report. Or, you can calculate the sum, minimum value, or maximum price of a area inside the element information.
Q16. Explain the time period “Data Skew” in Salesforce.

When such customers perform updates, performance troubles may be encountered due to “statistics skew”. This takes place when a unmarried person/ members of a single function own maximum of the facts for a selected item.
Q17. Explain thin desk. What are the issues for Skinny Table?
Ans: In Salesforce, skinny tables are used to get right of entry to regularly used fields and to avoid joins. This in large part improves performance. Skinny tables are relatively powerful, a lot so that even if the supply tables are modified, thin tables may be in sync with supply tables.
Considerations for skinny tables:
Skinny tables can include a maximum of a hundred columns.
Skinny tables cannot incorporate fields from different objects.
For full sandboxes: Skinny tables are copied in your Full sandbox agencies, as of the Summer ’15 release.

Primary keys (Id, Name and Owner fields).

Why are they so effective? Because take a look at training and test strategies affirm whether a particular piece of code is operating nicely or not. If that piece of code fails, then builders/ testers can correctly discover the test class having the faulty computer virus.
Test classes may be decided easily because every test magnificence will be annotated with@isTest keyword. In truth, if we do not annotate a check class with @isTest, then it can not be defined as a take a look at elegance.
