Izici zomshini:

Ikholomu yamukela idizayini yokuxhumeka kwesitimela esilayidi esinamandla amakhulu ukuze kuqinisekiswe amandla okushisela kanye nendlela yokubuyiswa kwengcindezi inamandla aphezulu futhi inemba eliphezulu.

• Ubuchwepheshe obuhlanganisiwe bokulawula ukushisela
• Ukulungiswa kwezinga eliphansi (ongakukhetha: inkundla yokushisela ye-XY)

Ukuphathwa kwedatha: isitoreji esakhelwe ngaphakathi noma ukudluliswa kwedatha yokushisela, ukulandelela okuhlakaniphile kwedatha

• Imodi yokusebenza ngokuhambisana nemithetho yokuphepha yaseYurophu
