The efficiency and versatility for the implementation of formulas in an on-demand database is improved. Formulas are categorized. Based at least partly on the categorization, formulas are evaluated synchronously or asynchronously. An asynchronous evaluation may be performed if a certain set of criteria is not satisfied. Asynchronous evaluations may be performed using a queue. During an asynchronous update of an object, a counter field and/or an estimate field may be used respectively for indicating the consistency of values of the object and a time when the values were consistent. The versatility of formulas is enhanced by using a formula to create a default value for a custom field when it is created and to determine whether an action is to be performed, and is enhanced by having an action define when a formula is to be updated.
