If you're familiar with Java Property Files (and in some ways Preferences), then Custom Settings may be considered an equivalent.

 

Two types - Hierarchical (can be referenced in Formula Fields and config too) and List.

 

Created from Setup > Develop > Custom Settings

 

API names of the Object and fields similar to a standard sObject. The great thing is that you don't need a SOQL Query to retrieve. For eg if Custom_Setting__c is ur custom setting (List Type), then you can retrieve a row with Name say 'FirstKey' by Custom_Setting__c.getInstance('FirstKey')

 

To apply it to your context, lets say you had an Error Code ERR001, which you saved in a Custom Setting Error_Messages__c, it can be rertrieved as Error_Messages__c.getInstance('ERR001')

This lets you have dynamic error messages, which are configurable

 

Here's a good post by the inimitable Jeff Douglas to get you started
