Salesforce Objects
• Similar to Tables (with more metadata)
• Standard objects out-of-the-box
• Account, Contact, Opportunity, …
• You can add custom fields to standard objects
• Rating__c, Twitter__c, …
• You can create custom objects
• i.e. Speaker__c, Session__c, Hotel__c
• Custom objects have standard fields
• Id, Owner, LastModifiedDate, LastModifiedBy, …

Apex Triggers

43.
Track: Developers
#CNX14
Trigger
• Apex code executed on database events
• Before or after:
• Insert
• Update
• Delete
• Undelete

44.
Track: Developers
#CNX14
Before or After?
• Before
• Update or validate values before they are saved to the database
• Example: Prevent double-booking of a speaker
• After
• Need access to values set by the database (Id, lastUpdated, …)
• Example: Send speaker confirmation email

45.
Track: Developers
#CNX14
Bulk Mode
• Trigger API designed to support bulk operations
• Data Import, Bulk API, etc.
• Triggers work on bulk of records, not single records
• Context variables provide access to data:
• Trigger.old and Trigger.new (List)
• Trigger.oldMap and Trigger.newMap (Map)

46.
Track: Developers
#CNX14
Example
Trigger on Account (after insert) {
