uphando iikhowudi zomthombo wethala leencwadi "Β»ngokuphunyezwa kweendlela , ukuvumela ukwenza imisebenzi yezibalo kwiseti yedatha ngokuchaneka okuphezulu ngokwaneleyo ngaphandle kokukwazi ukuchonga iirekhodi zomntu ngamnye kuyo. Ikhowudi yelayibrari ibhalwe kwi-C ++ kunye ilayisenisi phantsi kweApache 2.0.
Uhlalutyo olusebenzisa iindlela zabucala ezahlukeneyo luvumela imibutho ukuba yenze iisampulu zokuhlalutya kwiinkcukacha zamanani, ngaphandle kokubavumela ukuba bahlule idatha kwaye bahlukanise iiparitha zabantu abathile kulwazi oluqhelekileyo. Ngokomzekelo, ukuchonga ukungafani kokunyamekela kwesigulane, abaphandi banokunikwa ulwazi olubavumela ukuba baqhathanise umyinge wobude bokuhlala kwezigulane kwizibhedlele, kodwa ugcina imfihlo yesigulane kwaye ayigxininisi ulwazi lwesigulane.
Ithala leencwadi elicetywayo libandakanya ukuphunyezwa kweealgorithms ezininzi zokuvelisa izibalo ezidityanisiweyo ezisekelwe kwiiseti zedatha yamanani equka ulwazi oluyimfihlo. Ukujonga ukusebenza okuchanekileyo kwe-algorithms, inikwe . Ii-algorithms zikuvumela ukuba wenze isishwankathelo, ukubala, intsingiselo, ukutenxa okusemgangathweni, ukusasazwa kunye nokusebenza kweenkcukacha-manani kwidatha, kubandakanya ukumisela ubuncinci, ubuninzi kunye ne-median. Ikwabandakanya ukuphunyezwa , enokusetyenziselwa izibalo ezingagqunywanga ngobuchule obuchazwe kwangaphambili.
Ithala leencwadi lisebenzisa ulwakhiwo lweemodyuli olukuvumela ukuba wandise ukusebenza okukhoyo kunye nokongeza iindlela ezongezelelweyo, imisebenzi edibeneyo, kunye nolawulo lwenqanaba labucala.
Ngokusekwe kwithala leencwadi lePostgreSQL 11 DBMS ulwandiso oluneseti yemisebenzi edityanisiweyo engaziwa kusetyenziswa iindlela zabucala ezahlukileyo - ANON_COUNT, ANON_SUM, ANON_AVG, ANON_VAR, ANON_STDDEV kunye ANON_NTILE.
