Expression-based data may comprise data that is processed by a validation expression for example. After a validation expression is created it may then be performed with respect to one or more data values or data records. A validation expression returns a Boolean result that signifies a success or failure result. A validation expression can define complex intra-record tests and inter-record tests with unlimited complexity. In order to improve processing of validations, the system uses virtual data known as calculation fields. Calculation fields are stored in memory at runtime and not in a database thereby eliminating the necessity of selecting and updating records in the database. A dirty bit identifying fields and attributes that need to be calculated based on a dependent data may be used to defer calculation to a later time when the calculation field is displayed or a sort operation occurs for example.
