I need to save a value in a Salesforce Instance which should be universally accessible (In VisualForce Pages, Apex Classes). An example would be to save the account ID to link all contacts (from the apex code), username/password combination and so on. Out of the three methods listed below which one is the best?
- Static Resourcce
- Static Class
- Custom object with a single record (Get the value be querying the field)
