The invention relates to a method and apparatus for generating custom configured documents from a content database such as an airline database. The method uses component processes each defined by code, at least some of the component processes having variable parameters, and predefined workflow templates, each workflow template defining a series of component processes leading to the generation of a generic class of output document. To produce a specific output document, a particular workflow template and selection parameters are input. The values of the variable parameters of the component processes are calculated, and a scheduling engine then executes the code of the series of component processes defined in the particular workflow template. The workflow steps may include in particular extracting data from the content database depending on the determined values of the variable parameters; and generating a specific output document being an instance of the generic class of output document, the specific output document being defined by the particular workflow template, the data extracted from the content database, and a format determined by the workflow template and the variable parameters.
