Bulikfy Apex Code / Trigger

Bulkifying Apex code refers to the concept of making sure the code properly handles more than one record at a time.  If a batch of records (via the webservices call) invokes the same Apex code, all of those records need to be processed as a bulk, in order to write scalable code and avoid hitting governor limits.

eg.

trigger accountTestTrggr on Account (before insert, before update) {

   List<String> accountNames = new List<String>() {

 

   //Loop through all records in the Trigger.new collection

   for(Account a: Trigger.new){

      //Concatenate the Name and billingState into the Description field

      a.Description = a.Name + ':' + a.BillingState

   }

   

}
