See for example MSEkicadBOM, the application I am currently working on. https://gitlab.com/mseide-msegui/mseuniverse/tree/master/tools/kicad/bom It is a component and footprint database program for KiCad.
It consists of a datamodule with the program logic and the database and action components: http://mseide-msegui.sourceforge.net/pics/kicadbommainmo.png a mainform with the mainmenu, GUI actions and the main datagrid: http://mseide-msegui.sourceforge.net/pics/kicadbommainfo.png and several editforms: http://mseide-msegui.sourceforge.net/pics/kicadbomcomponented.png The editforms inherit from a common base editform with base functionality (datasource, navigator, timestamp display, window close logic...) and have no or GUI-code only. The connection GUI<>datamodule is made with TDataSource, action- and ifi-dataendpoint-components. If done right the RAD-approach is productive and convenient, the projects are easily extendable and maintainable.
