Management asked for opportunities to be automatically created for accounts with annual revenue greater than $1, 000,000. A developer created the following trigger on the Account object to satisfy this requirement.
for (Account a : Trigger.new) {
if (a.AnnualRevenue > 1000000) {
List<Opportunity> oppList = [SELECT Id FROM Opportunity WHERE AccountId = :a.Id]; if (oppList.size() == 0) { Opportunity oppty = new Opportunity(Name = a.Name, StageName = 'Prospecting', CloseDate = System.
today().addDays(30));
insert oppty;
}
}
}
Users are able to update the account records via the UI and can see an opportunity created for high annual revenue accounts. However, when the administrator tries to upload a list of 179 accounts using Data Loader, it fails with system, Exception errors.

Universal Hiring uses Salesforce to capture job applications. A salesforce administrator created two custom objects; Job__c acting as the master object, to Application_c acting as the detail.
Within the Job__c object, a custom multi-select picklist, preferred _Locations__c, contains a list of approved states for the position. Each Job_Application__c record relates to a Contact within the system through a master-detail relationship.
Recruiters have requested the ability to view whether the Contact's Mailing State value matches a value selected on the Preferred Locations__c field, within the Job_Application__c record. Recruiters would like this value to be kept in sync if changes occur to the Contact's Mailing State.
What is the recommended tool a developer should use to meet the business requirement?
