This manner, you could expand the software without any hassle and then migrate the metadata and data (if applicable) to the production surroundings. Doing this in a non-manufacturing environment permits developers to freely check and test applications quit to quit.

Types of Sandboxes are:


Developer Pro

Partial Copy


Q4. Can you edit an apex trigger/ apex elegance in manufacturing environment? Can you edit a Visualforce page in manufacturing environment?

Ans: No, it isn't feasible to edit apex training and triggers at once in production surroundings.

It desires to be completed first in Developer edition or trying out org or in Sandbox org. Then, to deploy it in manufacturing, a consumer with Author Apex permission should set up the triggers and training the use of deployment tools.

However, Visualforce pages may be created and edited in each sandbox and in manufacturing.

Only if the page has to do some thing particular (special values), it would have to be evolved through Sandbox.

Q5. What are the exclusive information sorts that a preferred subject report name can have?

Ans: A general subject report call could have information type of both auto variety or text area with a restrict of 80 chars.

The advantage is that in advance, we had to create custom fields to organization or phase positive records.

Q11. What are dynamic dashboards? Can dynamic dashboards be scheduled?

Ans: Before we apprehend dynamic dashboards, let us first recognize static dashboards.

Dependent fields will inherit the owner, sharing and protection settings from its grasp.

You can define master-detail relationships among  custom items, or between a custom item and general item as long as the same old item is the grasp inside the dating.

Lookup Relationship (1:n):-

Lookup relationships are used whilst you want to create a link between two gadgets, however with out the dependency at the figure object. Similar to Master-Detail dating, you may think of this as a form of figure-child dating wherein there is handiest one determine, but many children i.E. 1:n dating.

The distinction right here is that regardless of being controlling area, deleting a document will now not result in computerized deletion of the research subject in the baby item.

Junction Relationship (Many-To-Many):-

This kind of a dating can exist whilst there's a want to create two master-detail relationships. Two grasp-detail relationships can be created via linking 3 custom items. Here, two items will be master gadgets and the 0.33 item can be depending on both the items. In easier words, it is going to be a toddler object for each the master gadgets.


Q14. What happens to element document when a master record is deleted? What happens to toddler report while a determine report is deleted?

Ans: In a Master-Detail dating, while a master record is deleted, the element record is deleted mechanically (Cascade delete).

In a Lookup relationship, although the parent record is deleted, the kid file will not be deleted.

Q15. Can you've got a roll up precis discipline in case of Master-Detail relationship?

Ans: Yes. You may have a roll-up precis in case of a grasp-element relationship. But no longer in case of a lookup courting.

There are 4 calculations that you could do the usage of roll-up summary area. You can count number the variety of element statistics associated with a master report. Or, you can calculate the sum, minimum cost, or maximum value of a area in the detail facts.

Q16. Explain the term “Data Skew” in Salesforce.

Ans: “Data skew” is a situation which you may stumble upon when running for a huge purchaser wherein there are over 10,000 statistics. When one unmarried user owns that many facts we name that circumstance ‘ownership records skew’.

Q17. Explain skinny table. What are the considerations for Skinny Table?

Ans: In Salesforce, skinny tables are used to get admission to regularly used fields and to avoid joins. This in large part improves performance. Skinny tables are tremendously powerful, a lot in order that even if the source tables are modified, skinny tables might be in sync with source tables.

Considerations for thin tables:

Skinny tables can incorporate a maximum of one hundred columns.

Skinny tables can't contain fields from other objects.

For complete sandboxes: Skinny tables are copied on your Full sandbox corporations, as of the Summer ’15 release.

Ans: Only the following fields are automatically listed in Salesforce:

Primary keys (Id, Name and Owner fields).

Foreign keys (research or grasp-detail dating fields).

An instance of that is Sales Managers having access to information owned through Sales Reps while their friends do now not get get admission to to it.

Q25. What are the examples of non-deterministic Force.Com formulation fields?

Ans: Before I mention a number of the examples, permit me come up with an introduction to deterministic and non-deterministic formula fields.

Consequently, the modern-day person’s credentials are not used, and any consumer who has access to those techniques can use their complete electricity, regardless of permissions, field-level safety, or sharing regulations.

Developers who expose strategies the usage of the Apex REST annotations must therefore take care that they are no longer inadvertently exposing any touchy information. Look at the under piece of code as an instance:-

worldwide elegance AccountPlan 

webservice String vicinity;

webservice String location;
