18. The system of claim 15 , further comprising: means for presenting the preflight parameters; means for receiving updated preflight parameters; and means for updating the attribute information based on said updated preflight parameters.
15. A system, comprising: means for defining preflight parameters based on data types representing respective formats of the preflight parameters; means for creating a control interface for the preflight parameters based on at least one of the defined data types representing the respective formats of the preflight parameters; means for defining relationship information among the preflight parameters, the relationship information placing constraints on parameter values for the preflight parameters in the preflight rule to maintain consistency between the preflight parameters, the relationship information being used by at least one handler to check for the consistency; means for storing the relationship information to a relationship table that is accessible by the at least one handler to check for the consistency between parameter values of the first parameter and the second parameter in the preflight rule; means for generating, using at least one processor, attribute information summarizing the preflight parameters, the data types, and parameter values associated with the preflight parameters; and means for storing the attribute information for the preflight parameters in an attribute table uniquely associated with the preflight parameters from among a plurality of attribute tables.
