Cov sawv cev ntawm cov lej, raws li lub cev ntsuas ntawm qhov chaw ntawm daim duab nws tus kheej, yuav tsum ncaj qha proportional rau tus lej suav. Ntshiab, ncauj lus kom ntxaws thiab meej daim ntawv lo yuav tsum tau siv los yeej graphical distortion thiab ambiguity. Sau cov lus piav qhia ntawm tus cov ntaub ntawv ntawm daim duab nws tus kheej.
Xav txog qhov no, peb lub ntsiab lus tseem ceeb tshaj plaws ntawm kev pom cov ntaub ntawv yog dab tsi?
Txoj cai ntawm qhov pib credit unions yuav tsum internalize peb lub hauv paus ntsiab lus tseem ceeb ntawm kev pom zoo, 3 s: yooj yim, qauv thiab scalable
- Yooj yim hais txog qhov yooj yim uas cov ntawv qhia pom tuaj yeem txhais tau.
- Standard: Kev pom zoo xav tau cov qauv ntaub ntawv thiab cov ntsiab lus.
Dab tsi yog cov ntaub ntawv rau tus number case ratio? Cov ntaub ntawv - tus cwj mem yog lub ntsiab tsis-erasable ntawm ib daim duab, tsis-redundant tus cwj mem npaj nyob rau hauv teb rau variation nyob rau hauv cov zauv sawv cev. Cov cov ntaub ntawv - tus number case ratio yog qhov ratio ntawm Ink uas yog siv los qhia qhov tseeb cov ntaub ntawv piv rau tag nrho cov nyiaj ntawm tus cwj mem (los yog pixels) siv nyob rau hauv tag nrho cov zaub.
Tom qab ntawd, ib tus tuaj yeem nug, qhov twg ntawm Tufte cov ntsiab lus hais tias koj yuav tsum tsis txhob cuam tshuam cov ntaub ntawv?
Tufte lub hauv paus ntsiab lus uas hais uas koj yuav tsum tsis txhob distort cov ntaub ntawv yog cov ntaub ntawv tus number case ratio. Tufte hais tias uas cov ntaub ntawv ink yog ib tug tsis erasable number case. Cov ntsiab lus tuaj yeem ploj ntawm daim duab yog tias cov ntaub ntawv number case raug tshem tawm ntawm daim duab. Cov mis rau xam cov ntaub ntawv ink yog = cov ntaub ntawv ink/tag nrho ink siv los luam cov duab.
Lub hauv paus ntsiab lus twg yuav ua kom muaj kev ncaj ncees graphical thiab graphical zoo?
Tufte's 6 Principles of Graphical Integrity
- Kev sawv cev ntawm tus lej yuav tsum sib phim qhov tseeb proportions.
- Labeling yuav tsum meej thiab meej.
- Tsim yuav tsum tsis txhob sib txawv rau ib co ulterior motive, qhia tsuas yog cov ntaub ntawv variation.
- Txhawm rau sawv cev rau cov nyiaj, cov cuab yeej paub zoo yog qhov zoo tshaj plaws.

Dab tsi yog qhov txawv ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb?
Qhov sib txawv loj ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb Ib daim ntawv XML muaj cov ntaub ntawv hais txog kev sib raug zoo ntawm cov ntaub ntawv rau ib leeg nyob rau hauv daim ntawv ntawm hierarchy. Nrog rau tus qauv kev sib raug zoo, tib hom kev sib raug zoo uas tuaj yeem txhais tau yog cov lus niam txiv thiab cov rooj sib raug zoo
Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Thaum cov lus tau hla tawm cov ntaub ntawv kuaj xyuas feem ntau nthuav tawm cov ntawv sau thawj nrog kev pab ntawm dab tsi?
Infrared luminescence yog siv rau: Qhia tawm cov ntawv sau uas tau muab tshem tawm THIAB kuaj pom yog tias ob tus lej sib txawv tau siv rau hauv kev sau ntawv. Cov kws tshuaj xyuas cov ntaub ntawv feem ntau nthuav tawm cov ntawv sau thawj ntawm cov lus uas tau hla nrog kev pab ntawm: Infrared tawg
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 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
