Impembelelo yokubhala lo mzobo yayilinqaku . Ndifumene inqaku elipapashwe kwiminyaka eyi-4 eyadlulayo linomdla - .
Kwakubonakala kunomdla ukuba ingcamango efanayo - "sebenzisa ingqiqo yoshishino kwisiseko sedatha".
Yayingendim kuphela owathi qatha engqondweni.
Kwakhona, kwixesha elizayo, ndandifuna ukugcina, okokuqala, kum, uphuhliso olunomdla olwavela ngexesha lokuphunyezwa. Ngokukodwa ngokuqwalasela ukuba kutsha nje kuye kwenziwa isigqibo esicwangcisiweyo sokutshintsha i-architecture kunye nokudlulisa ingqiqo yeshishini kwinqanaba le-backend. Ukuze yonke into ephuhlisiwe kungekudala ingabi namsebenzi nakubani kwaye ayiyi kuba nomdla nakubani na.
Iindlela ezichaziweyo ayilohlobo oluthile lokufunyanwa okanye olukhethekileyo. uyazi njani, yonke into i-classic kwaye iphunyezwe ngamaxesha amaninzi (umzekelo, ndasebenzisa indlela efanayo kwiminyaka eyi-20 edlulileyo kwi-Oracle) Ndagqiba ekubeni ndiqokelele yonke into kwindawo enye. Kwimeko apho iza luncedo kumntu. Njengoko uqheliselo lubonisile, kaninzi ingcamango efanayo iza kubantu abohlukeneyo ngokuzimeleyo. Kwaye kuluncedo ukuzigcinela yona njengesikhumbuzo.
Ngokuqinisekileyo, akukho nto kweli hlabathi igqibeleleyo, iimpazamo kunye neetypos ngelishwa zinokwenzeka. Ukugxekwa kunye nezimvo zamkelwe ngamandla kwaye ziyalindeleka.Kwaye enye inkcukacha encinci ngakumbi - iinkcukacha ezithe ngqo zophumezo azifakwanga. Nangona kunjalo, yonke into isasetyenziswa kwiprojekthi esebenzayo. Ngoko, inqaku lingumzobo nje kunye nenkcazo yengcamango jikelele, akukho nto. Ndiyathemba ukuba kukho iinkcukacha ezaneleyo zokuqonda umfanekiso opheleleyo.
Umbono jikelele "ukwahlula kwaye unqobe, ufihle kwaye ube ngumnikazi"
Ingcamango yeklasikhi - i-schema eyahlukileyo yeetafile, i-schema eyahlukileyo kwimisebenzi egciniweyo.
Umxhasi akanakho ukufikelela kwidatha ngokuthe ngqo. Yonke into eyenziwa ngumxhasi kukufowunela umsebenzi ogciniweyo kwaye iqhubekisele phambili impendulo efunyenweyo.
