Linear Data Structure
Cov ntaub ntawv qauv qhov twg cov ntaub ntawv cov ntsiab lus tau teem caij los yog linearly qhov twg cov ntsiab lus txuas nrog nws yav dhau los thiab tom ntej uas nyob ib sab hauv qhov hu ua a linear cov ntaub ntawv qauv . Hauv linear cov ntaub ntawv qauv , ib theem yog koom nrog. Yog li ntawd, peb tuaj yeem hla tag nrho cov ntsiab lus hauv ib qho kev khiav nkaus xwb
Hauv qhov no, cov ntaub ntawv linear yog dab tsi?
Linear cov ntaub ntawv qauv : A linear cov ntaub ntawv qauv hla tus cov ntaub ntawv cov ntsiab lus sequentially, uas tsuas yog ib qho cov ntaub ntawv element tuaj yeem ncav cuag. Piv txwv li: Arrays, Linked Lists. Tsis- Linear cov ntaub ntawv qauv : Txhua cov ntaub ntawv yam khoom yog txuas rau ob peb lwm yam cov ntaub ntawv cov khoom nyob rau hauv ib txoj kev uas tshwj xeeb rau kev xav txog kev sib raug zoo.
Tom qab, lo lus nug yog, hom ntaub ntawv qauv yog dab tsi? Cov txheej txheem ntawm kev npaj cov ntaub ntawv ntsig txog yog hu ua ' cov ntaub ntawv qauv '. Cov hom ntaub ntawv qauv yog: Cov Npe: Ib pawg ntawm cov khoom zoo sib xws nrog kev sib txuas rau yav dhau los lossis / thiab tom ntej cov ntaub ntawv cov khoom. Arrays: Ib txheej ntawm homogeneous tus nqi. Cov ntaub ntawv: Ib pawg ntawm cov teb, qhov twg txhua daim teb muaj cov ntaub ntawv belongs rau ib hom ntaub ntawv.
Yog li ntawd, dab tsi yog linear data structure piav nrog piv txwv?
Linear Data Structure : Piv txwv ntawm linear cov ntaub ntawv qauv yog array, stacks, queue, thiab linked list. Lawv tuaj yeem ua tiav hauv kev nco siv ob txoj hauv kev. Thawj txoj kev yog los ntawm kev muaj kab tawm kev sib raug zoo ntawm cov ntsiab lus los ntawm kev ua raws li qhov chaw nco.
Dab tsi yog linear thiab nonlinear qauv?
1. Ib a kab tawm cov ntaub ntawv qauv , cov ntaub ntawv cov ntsiab lus yog teem rau hauv a kab tawm kev txiav txim qhov twg txhua thiab txhua lub ntsiab lus txuas rau nws yav dhau los thiab tom ntej uas nyob ib sab. Hauv ib tsis yog - kab tawm cov ntaub ntawv qauv , cov ntaub ntawv ntsiab lus txuas nrog hauv hierarchically. Hauv kab tawm cov ntaub ntawv qauv , cov ntaub ntawv ntsiab lus tuaj yeem hla hauv ib qho kev khiav nkaus xwb.

Cov ntaub ntawv hom thiab cov qauv ntaub ntawv yog dab tsi?
Cov qauv ntaub ntawv yog ib txoj hauv kev piav qhia txog ib txoj hauv kev los npaj cov ntaub ntawv kom ua haujlwm andalogrithms tuaj yeem siv tau yooj yim dua. Ib hom ntaub ntawv piav qhia txog cov ntaub ntawv uas txhua tus sib koom ua ke. Piv txwv li tus lej cov ntaub ntawv hom piav qhia txhua tus lej uas lub khoos phis tawj tuaj yeem ua tau
Dab tsi yog linear thiab nonlinear hauv cov ntaub ntawv qauv?
1. Nyob rau hauv ib tug linear cov ntaub ntawv qauv, cov ntaub ntawv ntsiab yog teem nyob rau hauv ib tug linear kev txiav txim qhov twg txhua thiab txhua yam yog txuas rau nws yav dhau los thiab tom ntej no nyob ib sab. Nyob rau hauv cov ntaub ntawv uas tsis yog-linear, cov ntaub ntawv cov ntsiab lus txuas rau hauv hierarchically. Hauv cov ntaub ntawv linear, cov ntaub ntawv cov ntsiab lus tuaj yeem hla hauv ib qho kev khiav nkaus xwb
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog qhov sib txawv ntawm cov qauv siv nyob rau hauv cov ntaub ntawv ntawm cov khoom oriented qauv?
Cov qauv tseem ceeb ntawm cov qauv uas siv rau hauv cov khoom siv yog: Siv cov qauv qauv, Cov qauv qauv (zoo li qub) cov qauv, Cov qauv coj tus cwj pwm (dynamic) khoom qauv
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
