Business problems

Because this requirement means that many child records (opportunities) need to be updated when a parent record (Account) is edited, we can't achieve the preceding business requirement using the Workflow rule. The next possibility is to use an Apex trigger. Generally, a developer writes an Apex trigger on the Account object to update all the open opportunities when an account's custom field, out of business, gets updated to True. The following is the sample code:

trigger UpdateRelatedOpportunites on Account (after update) {
  for (Account AccountToUpdate : trigger.new)
    {
        If (AccountToUpdate.Out_Of_Business__c==True)
        {
        // Your logic;
        }
    }
}

In addition, you'll need a test class, and then use a change set to deploy the trigger and test classes to production. This also means that any change to the business logic will require more development work.

Another way to achieve the same business requirement is to use a combination of Visual Workflow and autolaunch Flow/Process Builder. Here is the description of the next screenshot:

The following screenshot represents solutions for a similar business scenario by using Visual Workflow and Process Builder:

Process Builder is one of the ways to automate complex business processes using click not code similar to the Workflow rule and Visual Workflow. We will discuss more about this in Chapter 5, Developing Applications with Process Builder.

We can't achieve this goal by the Workflow rule. For this, we have to write an Apex class that implements the Schedulable interface for the class and then use Schedule Apex to run it on a regular basis. The following is the code for this Apex class:

global class SendChatterEmail implements Schedulable
{
    global SendChatterEmail (){
      // Batch Constructor
    }

    // Start Method
    global Database.QueryLocator start(){
      /* Use SOQL query to get the records you want to operate upon
      select Id, fullPhotoUrl from User where isactive = true AND FullPhotoUrl    like '%photo/005%'*/
    }

    // Execute Logic
    global void execute(){
      // perform the operation

    }

    global void finish(){
      // Logic which we want to execute at finish
    }
}

An alternative way to accomplish the same business requirement is to use a combination of Visual Workflow and Process Builder. Here is the description of the next screenshot:
