Nginikeze isifinyezo semisho emibili yombhalo olandelayo: "Umdwebo kaVenn ubonisa ubudlelwano phakathi kwamasethi amabili noma ngaphezulu edatha. Imidwebo kaVenn iwusizo ngokukhethekile ekuqhakambiseni ukufana nokungafani futhi ngokuvamile isetshenziselwa ukuqhathanisa nokuqhathanisa izici zamaqoqo wedatha ahlukene.  Kumdwebo kaVenn, kusetshenziswa imibuthano ukumela isethi ngayinye yedatha. Ngaphakathi kwesiyingi ngasinye kunohlu lwezici ezichaza leyo mininingwane. Izici ezifanayo phakathi kwamasethi amabili noma ngaphezulu edatha zifakwe ohlwini endaweni lapho imibuthano ihlangana khona. Imidwebo elula kaVenn iqukethe imibuthano emibili ehlanganayo, kodwa imidwebo eyinkimbinkimbi kaVenn ingaqhathanisa amasethi wedatha afinyelela kwayisihlanu noma ngaphezulu kusetshenziswa imibuthano efinyelela kwayisihlanu noma ngaphezulu.  Imidwebo kaVenn ivame ukusetshenziswa kwezamabhizinisi nakwezemfundo ukuze kuboniswe futhi kuhlolwe ukuthi izinto zihlobana kanjani. Emkhakheni wezamabhizinisi, imidwebo kaVenn ivame ukusetshenziswa ekuthuthukiseni umkhiqizo, ukumaketha, ukuphathwa, nokunye".
Umdwebo kaVenn wuhlobo oluvame ukusetshenziswa kakhulu kwezamabhizinisi nakwezemfundo ukukhombisa ukufana nokungafani phakathi (okungenani) kwamasethi amabili wedatha. Emidwebweni kaVenn, kuvame ukuba khona imibuthano emibili engqubuzanayo kancane emele amasethi wedatha amabili ahlukene futhi ukuhlangana kwale mibuthano kuqukethe izici zokufana phakathi kwamasethi wedatha futhi umehluko we-symmetric wale mibuthano uqukethe umehluko phakathi kwalawa masethi wedatha amabili.
