CSV mtundu kapena kumene kuika koma?

Mwa ntchito, anakumana ngati si mapulogalamu, ndi kale ndi wosuta kukalamba deta inatha ku ntchito wina ndi mzake zimachokeradi kawirikawiri. Ndipo nthawi zambiri m'pofunika kuitanitsa deta tabular, chimenenso, anayamba ndi CSV mtundu. Amene anayambitsa njira zingapo zina (XML mtsogoleri pakati pawo). Koma chilengedwe cha wapamwamba CSV, zina, ndi njira yabwino kwambiri, ndi zina - ndi mabvuto ambiri.

Amayimira dzina la mtundu ngati commaseparatedvalues - koma anasiyana mfundo. Mu kope file motere:

00, 01, 02, 03;

01, 15, 34, 11;

16, 27, 33, 06 (kumapeto kwa chizindikiro mumaika safunikira)

Ndipo mu kupambana spreadsheet kapena ofanana ntchito kale kwambiri:

Koma tsopano tinakambirana nkhani zosavuta. Mavuto anayamba chifukwa chabe chakuti chifukwa malipoti wothinikizidwa kwambiri deta mtundu CSV ntchito kusamutsa yambiri zambiri. Nthawi zambiri amapezeka mu zinasokoneza makompyuta a makhalidwe osiyanasiyana: M'ndandanda, Alpha, alphanumeric, ndi malo, etc. Nthawi zambiri magulu lalikulu ndi zolakwa, ndi ngati Mwachitsanzo, kwinakwake adzakhala koma lowonjezera nkhani mmodzi wa m'minda, maselo onse akhoza osamukira ndi mmodzi.

Nthawi zambiri, mavuto pamene deta ndi kunja kudzera wapamwamba mtundu CSV, zikhoza kugawidwa m'magulu atatu:

1 - Pachithunzichi kudzazidwa minda.

2 - Pachithunzichi deta kutembenuka pamene yopulumutsa kuti CSV wapamwamba.

3 - kuzindikira Pachithunzichi pulogalamu mtundu importer.

Mbali yoyamba ife pang'ono mwafufuza. Pofuna vuto, muyenera kupereka njira kuyan'anila kulondola kwa deta analowa. Mwachitsanzo, ngati mukufuna kusonkhanitsa Nawonso achichepere a adilesi mndandanda yamakalata, pali zolembedwa wapadera kuti atsimikize ngati munthu yemwe analowa maimelo mtundu woyenera. Kodi pali mipata, mipatuliro, ndi deta ina iliyonse imene angathe kuwerenga cholakwika, nkhani za m'munda ayenera unazunguliridwa mu zizindikiro ogwidwawo (otchedwa kompyuta "").

Nkhani yachiwiri chikugwirizana ndi kusankha kabisidwe. Muyenera kupeza nthawi zambiri anakumana ndi zimene kabisidwe amakonda yoti pulogalamu. Mu Windows amagwiritsidwa ntchito mu 1251, choncho ngati wapamwamba woyambirirawo kukumana lemba kuti Unicode, kutsatira adzakhululukidwa chaonetsedwera mu ntchito kopita monga unyolo wa mafunso. Mu kupambana, mungathe kupulumutsa ku CSV mtundu ndi kabisidwe osiyana ndi delimiter (kupatula mfundo akugwiritsabe ntchito tsamba, ndi semicolon), koma ndi bwino kulenga file mu kope ++ kapena OpenOfficeCalc.

Nkhani yachitatu - chifukwa wachiwiri. Mbiri yakale, mtundu CSV alibe muyezo umodzi. mapulogalamu ambiri amaona CSV ndi TSV file (tsamba-delimited) ndi SCSV (ankasiyana semicolons), makamaka chifukwa file kutambasuka si ponena za izo. Pankhaniyi, deta ndi kuwerenga molondola ndipo si allocated mwa maselo m'ndondomeko. The chinthu chabwino chimene tingachite amalangiza - kulenga wapamwamba CSV panokha. Monga tanenera kale, pamafunika kuti agwiritse ntchito mkonzi yabwino.

Zidule mmene zikhale ndi CSV mtundu, wodziwika mapulogalamu. Zambiri wosuta afunika kutsatira malangizo athu polenga wapamwamba. Wamng'ono wa mavuto onse kumachitika pamene wapamwamba analengedwa mwachindunji inatha ku ntchito yeniyeni (ndi zina mwa njira ina). Ndi kosavuta kuganizira mavuto onse zotheka nawo mu deta.
