Analytical snapshot allows reports run at scheduled time to be stored as objects. Analytical snapshots are used to perform trend analysis. As an example if we want to view how monthly sales are growing, fields in a report with sales figure can be stored in a custom object every month using Analytical snapshot. Data in this custom object can then be used to perform trend analysis.

Analytical snapshot are available from the Data Management menu option. Source report in Analytical snapshot can be of the type Tabular or Summary.

What is an Attribute in Lightning? The attribute is like a member variable in our regular coding (like declare variables in Apex, JavaScript). In simple words, attributes are used to store information to be referenced and used in our lightning component code. An attribute will make your lightning component more dynamic

An assignment rule in Salesforce is used to define to whom case or lead is assigned based on the specified criteria. Most of the organizations have one particular rule for the overall purpose. For example, there could on lead assignment rule for web-generated leads and one case assignment rule for the holiday use

You can override a standard action with an Aura component in both Lightning Experience and mobile.
You need at least one Aura component in your org that implements the lightning:actionOverride interface. You can use a custom component of your own, or a component from a managed package.
Go to the object management settings for the object with the action you plan to override.
Select Buttons, Links, and Actions.
Select Edit for the action you want to override.
Select Lightning component for the area you want to set the override.
From the drop-down menu, select the name of the Lightning component to use as the action override.
Select Save.

Trigger.old: Returns a list of the old versions of the sObject records.
Note that this sObject list is only available in the update and delete triggers.

Trigger.oldMap: A map of IDs to the old versions of the sObject records.

Note that this map is only available in the update and delete triggers.

Before triggers are used to update or validate record values before they're saved to the database. After triggers are used to access field values that are set by the system (such as a record's Id or LastModifiedDate field), and to effect changes in other records. The records that fire the after trigger are read-only

To avoid recursive triggers you can create a class with a static Boolean variable with default value true. In the trigger, before executing your code keep a check that the variable is true or not. Once you check make the variable false

1. The original record is loaded from the database (or initialized for an insert statement)
2. The new record field values are loaded from the request and overwrite the old values
3. All before triggers execute (TRIGGERS)
4. System validation occurs, such as verifying that all required fields have a non-null value, and running any user-defined validation rules (VALIDATIONS)
5. The record is saved to the database, but not yet committed
6. All after triggers execute
7. Assignment rules execute
8. Auto-response rules execute
9. Workflow rules execute (WORKFLOW)
10. If there are workflow field updates, the record is updated again
11. If the record was updated with workflow field updates, before and after triggers fire one more time (and only one more time)
12. Escalation rules execute
13. All DML operations are committed to the database
14. Post-commit logic executes, such as sending email

After triggers are used to access field values that are set by the system (such as a record's Id or LastModifiedDate field), and to affect changes in other records, such as logging into an audit table or firing asynchronous events with a queue. The records that fire the after trigger are read-only.

Hi,

 

Trigger.new : Returns a list of the new versions of the sObject records. Note that this sObject list is only available in insert and update triggers, and the records can only be modified in before triggers.

 

Trigger.old : Returns a list of the old versions of the sObject records. Note that this sObject list is only available in update and delete triggers

Inline editing is a feature by which one can edit a record without pressing the edit button.User goes to the detail page, doubles click on a field, changes to a new value and presses save. This process makes sure the field value is updated to the new value

Profiles help to control object privileges such as CRED (Create, Read, Edit, Delete). They also contain system permissions that a user can carry out such as exporting data.
Roles on the other hand help with sharing records across an organization. They work in a hierarchical fashion, giving users access to records that are owned by people lower down in the hierarchy.

The sObject might change between the time you call the method and the time it executes. In this case, the future method will get the old sObject values and might overwrite them. To work with sObjects that already exist in the database, pass the sObject ID instead (or collection of IDs) and use the ID to perform a query for the most up-to-date record. The following example shows how to do so with a list of IDs.

Compound fields group together multiple elements of primitive data types, such as numbers or strings, to represent complex data types, such as a location or an address. Compound fields are an abstraction that can simplify application code that handles the values, leading to more concise, understandable code.

3 types of compound fields

1. Address Compound Fields
2. Geolocation Compound Field
3. Compound Field Considerations and Limitations

A big object stores and manages massive amounts of data on the Salesforce platform. You can archive data from other objects or bring massive datasets from outside systems into a big object to get a full view of your customers. Clients and external systems use a standard set of APIs to access big object data. A big object provides consistent performance, whether you have 1 million records, 100 million, or even 1 billion. This scale gives a big object its power and defines its features.

There is no way to call visualforce page in a trigger.

If you try to insert a record on one VF page and after hitting Save you want to be redirected to a specific page, I suggest you to check PageReference Class.

After you call insert in a controller you should return a PageReference instance with URL you want user to be redirected to.
