An application framework that includes modular components is disclosed that simplifies development of web-based applications. The application framework may be written in Java based on servlet/JSP. Through the use of components that include at least a data model object, a view object, and a data storage object, the application framework can be reconfigured to retrieve and display any number of data fields without changing the underlying user-interface code. The data model object provides a standardized matrix of data objects, which are used to map data from virtually any data source to the user interface. The view object takes data from the data model object and presents it for display. The data storage object enables CREATE, READ, UPDATE, and DELETE operations related to data access. The data storage object maps data from data storage to the data model object in an order specified by the data model object.
