Chilimbikitso cholemba chojambulachi chinali nkhaniyo . Ndapezanso nkhani yomwe idasindikizidwa zaka 4 zapitazo kukhala yosangalatsa - .
Zinkawoneka zosangalatsa kuti lingaliro lomwelo - "khazikitsani malingaliro abizinesi mu database".
Siine ndekha amene ndinabwera mβmaganizo.
Komanso, m'tsogolomu, ndinkafuna kusunga, choyamba, kwa ine ndekha, zochitika zosangalatsa zomwe zidachitika panthawi yokhazikitsidwa. Makamaka poganizira kuti posachedwapa lingaliro lachidziwitso lidapangidwa kuti lisinthe zomangamanga ndikusintha malingaliro abizinesi kupita ku gawo lakumbuyo. Kotero kuti chirichonse chomwe chapangidwa posachedwapa sichidzakhala chothandiza kwa aliyense ndipo sichidzakhala ndi chidwi ndi aliyense.
Njira zomwe zafotokozedwazo si zamtundu wina wotulukira kapena zapadera. mukudziwa momwe, Chilichonse ndi chapamwamba ndipo chakhala chikugwiritsidwa ntchito kangapo (mwachitsanzo, ndinagwiritsa ntchito njira yofananira zaka 20 zapitazo pa Oracle) Ndinangoganiza zosonkhanitsa chirichonse pamalo amodzi. Zikafika pothandiza munthu. Monga momwe zasonyezera, nthawi zambiri lingaliro lomwelo limabwera kwa anthu osiyanasiyana paokha. Ndipo ndizothandiza kuzisungira nokha ngati chikumbutso.
Zoonadi, palibe chilichonse m'dziko lino chomwe chili changwiro, zolakwa ndi typos mwatsoka ndizotheka. Kudzudzula ndi ndemanga zimalandiridwa kwambiri ndikuyembekezeredwa.Ndiponso mfundo ina yaying'ono - tsatanetsatane wokhudza kukhazikitsa sikunatchulidwe. Komabe, chilichonse chikugwiritsidwabe ntchito muntchito yeniyeni yogwira ntchito. Chifukwa chake, nkhaniyi ndi chithunzi chabe komanso kufotokozera za lingaliro lonse, palibenso china.

Lingaliro lalikulu ndi "gawikana ndikugonjetsa, bisala ndi kukhala"
Lingaliro ndi lachikale - schema yosiyana ya matebulo, schema yosiyana ya ntchito zosungidwa.
