Hangarau kiritaki-tūmau

hangarau kiritaki-tūmau whakarato rua tukanga motuhake pāhekoheko - tūmau me te kiritaki, te hononga i waenganui i a ratou i runga i te whatunga.

E huaina tūmau te tukanga kawenga mo te tautoko o te pātengi raraunga me te pūnaha kōnae, me te kiritaki - te tukanga e unga tono me tatari mo te whakautu i te tūmau.

whakamahia tauira Kiritaki-tūmau te i hanga i te pūnaha tukatuka mōhiohio i runga i te pūtake o te pātengi raraunga, me te te pūnaha poutāpeta. He ko te hoahoanga kōnae-tūmau pera-ka karanga e te mea tino rerekē i te kiritaki-tūmau.

Raraunga i roto i te pūnaha tūmau kōnae rongoa i runga i te tūmau kōnae (Novell NetWare WindowsNT Tūmau ranei), a kua tukatuka ratou i roto i te mahi o nga wāhimahi "pātengi raraunga papamahi", pērā i Access, Paradox, FoxPro, me ētahi atu

Pātengi Raraunga kei i te taupunimahi, me raraunga whawhe whakamana e rave rahi tukanga motuhake, me te uncoordinated. raraunga katoa te kupu tuku ki runga i te tūmau whatunga ki te taupunimahi, e pōturi iho te tere o te tukatuka mōhiohio.

whakatinana hangarau kiritaki-tūmau te te mahi o te rua (i te iti rawa) tono - kiritaki me tūmau e faaite i te mahi i waenganui i a ratou. Hoki te rokiroki me te whawhe tika o te tūmau raraunga pahono, he tauira o e taea e SQLServer, Oracle, Sybase, me ētahi atu.
