Popeza kuti mapulogalamu amalembedwabe ndi opanga mapuloteni, ndipo nthawi zambiri palibe njira yoyesera, kuphatikizapo mapulogalamu sagwiritsidwa ntchito kawirikawiri pogwiritsa ntchito "zochita zabwino" (zomwe zimakhalanso mapulogalamu ndipo chifukwa chake zimakhala zopanda ungwiro), olamulira amachitidwe nthawi zambiri amayenera kuthetsa mavuto omwe amamveka mwachidule koma mwachidule: "bwererani momwe zinalili", "bweretsani maziko kuti agwire bwino ntchito", "amagwira ntchito pang'onopang'ono - bwererani", komanso zomwe ndimakonda "Sindikudziwa chiyani, koma konzekerani".
Kuphatikiza pa zolakwika zomveka zomwe zimachitika chifukwa cha ntchito yosasamala ya omanga, kapena kuphatikiza kwa zochitika, komanso chidziwitso chosakwanira kapena kusamvetsetsa kwazinthu zazing'ono zamapulogalamu omanga - kuphatikiza kulumikiza ndi machitidwe, kuphatikiza machitidwe opangira, madalaivala ndi firmware - palinso zolakwika zina. Mwachitsanzo, omanga ambiri amadalira nthawi yothamanga, kuiwalatu za malamulo a thupi, omwe sangathe kulepheretsa kugwiritsa ntchito mapulogalamu. Izi zikuphatikiza kudalirika kosatha kwa disk subsystem ndipo, kawirikawiri, njira iliyonse yosungiramo data (kuphatikiza RAM ndi processor cache!), ndi zero processing nthawi pa purosesa, komanso kusakhalapo kwa zolakwika pakufalitsa pa netiweki komanso pakukonza pa purosesa, ndi network latency, yomwe ili yofanana ndi 0. Simuyenera kunyalanyaza tsiku lomaliza lodziwika bwino, chifukwa ngati simukukwaniritsa nthawi, padzakhala mavuto oipitsitsa kuposa ma nuances a network ndi disk operation.
Zoyenera kuchita ndi zovuta zomwe zimakwera mwamphamvu ndikukhazikika pa data yamtengo wapatali? Palibe chomwe chingalowe m'malo mwa opanga amoyo, ndipo sizowona kuti zidzatheka posachedwa. Kumbali inayi, mapulojekiti ochepa okha ndi omwe adakwanitsa kutsimikizira kuti pulogalamuyi idzagwira ntchito monga momwe adafunira, ndipo sizingakhale zotheka kutenga ndi kugwiritsa ntchito umboni kuzinthu zina zofanana. Komanso, umboni woterewu umatenga nthawi yochuluka ndipo umafuna luso lapadera ndi chidziwitso, ndipo izi zimachepetsa mwayi wogwiritsa ntchito poganizira masiku omalizira. Kuphatikiza apo, sitikudziwa momwe tingagwiritsire ntchito ukadaulo wapamwamba kwambiri, wotsika mtengo komanso wodalirika kwambiri posungira, kukonza ndi kutumiza zidziwitso. Ukadaulo wotere, ngati ulipo, uli mu mawonekedwe amalingaliro, kapena - nthawi zambiri - m'mabuku opeka a sayansi ndi mafilimu.

Nayi lingaliro laling'ono
Gulu lililonse limakhala lokhazikika. Chilengedwe sichimagawa. Timagawa chifukwa ndi yabwino kwa ife. Ndipo timagawa molingana ndi deta yomwe timatengeranso mosasamala.
- Jean Bruler
Mosasamala kanthu za njira yosungiramo thupi, kusungirako deta zomveka kungathe kugawidwa m'njira ziwiri zopezera deta iyi: chipika ndi fayilo. Kugawanika uku kwakhala kosawoneka bwino posachedwa, chifukwa block block, komanso fayilo yokhayo, kusungidwa koyenera kulibe. Komabe, kuphweka, tidzaganiza kuti alipo.
Kuletsa kusungirako deta kumatanthauza kuti pali chipangizo chakuthupi chomwe deta imalembedwa m'magawo ena okhazikika, midadada. Miluko imapezeka pa adilesi inayake; chipika chilichonse chimakhala ndi adilesi yake mkati mwa chipangizocho.
Zosunga zobwezeretsera nthawi zambiri zimapangidwa ndi kukopera midadada ya data. Kuonetsetsa kukhulupirika kwa deta, kujambula kwa midadada yatsopano, komanso kusintha kwa zomwe zilipo kale, zimayimitsidwa panthawi yojambula. Ngati titenga fanizo kuchokera kudziko wamba, chinthu chapafupi kwambiri ndi chipinda chokhala ndi ma cell ofanana.
Kusungirako deta yamafayilo kutengera mfundo yomveka ya chipangizocho kuli pafupi ndi kusungirako zotchinga ndipo nthawi zambiri kumakonzedwa pamwamba. Kusiyana kwakukulu ndi kukhalapo kwa utsogoleri wosungirako zinthu komanso mayina owerengeka ndi anthu. Chidziwitso chimaperekedwa mu mawonekedwe a fayilo - malo otchedwa deta, komanso chikwatu - fayilo yapadera yomwe mafotokozedwe ndi kupeza mafayilo ena amasungidwa. Mafayilo amatha kuperekedwa ndi metadata yowonjezera: nthawi yolenga, mbendera zofikira, ndi zina. Zosunga zobwezeretsera nthawi zambiri zimachitika motere: amayang'ana mafayilo osinthidwa, kenako amawakopera kumalo ena osungira mafayilo omwe ali ndi mawonekedwe omwewo. Kukhulupirika kwa data nthawi zambiri kumachitika chifukwa chakusowa kwa mafayilo omwe amalembedwera. Fayilo metadata imasungidwa chimodzimodzi. Fanizo lapafupi kwambiri ndi laibulale, yomwe ili ndi magawo okhala ndi mabuku osiyanasiyana, komanso ili ndi kalozera wokhala ndi mayina owerengeka ndi anthu a mabuku.
Posachedwapa, njira ina imafotokozedwa nthawi zina, yomwe, makamaka, kusungirako deta ya fayilo kunayamba, ndipo ili ndi zinthu zakale zomwezo: kusungirako deta ya chinthu.
Zimasiyana ndi kusungirako mafayilo chifukwa alibe chisa choposa chimodzi (flat scheme), ndipo mayina a mafayilo, ngakhale kuti amawerengedwa ndi anthu, akadali oyenera kukonzedwa ndi makina. Mukamasunga zosunga zobwezeretsera, kusungirako zinthu nthawi zambiri kumachitidwa mofanana ndi kusungirako mafayilo, koma nthawi zina pali zosankha zina.
- Pali mitundu iwiri ya oyang'anira makina, omwe sapanga zosunga zobwezeretsera, ndi omwe AMAtero.
- Kwenikweni, pali mitundu itatu: palinso omwe amafufuza kuti zosunga zobwezeretsera zitha kubwezeretsedwanso.-Zosadziwika
M'pofunikanso kumvetsa kuti ndondomeko zosunga zobwezeretsera deta palokha ikuchitika ndi mapulogalamu, kotero ili ndi kuipa onse ofanana ndi pulogalamu ina iliyonse. Kuchotsa (osati kuchotsa!) Kudalira pa chinthu chaumunthu, komanso mawonekedwe - omwe payekha alibe mphamvu yamphamvu, koma palimodzi akhoza kupereka zotsatira zowoneka - zomwe zimatchedwa lamulo 3-2-1. Pali zosankha zambiri za momwe mungafotokozere, koma ndimakonda kutanthauzira kotereku bwino: 3 seti za deta zomwezo ziyenera kusungidwa, ma seti a 2 ayenera kusungidwa m'mawonekedwe osiyanasiyana, ndipo seti ya 1 iyenera kusungidwa kumalo osungirako kutali.
Mawonekedwe osungira ayenera kumveka motere:
- Ngati pali kudalira njira yosungirako thupi, timasintha njira yakuthupi.
- Ngati pali kudalira njira yosungiramo zomveka, timasintha njira yomveka.
Kuti mukwaniritse zotsatira zazikulu za lamulo la 3-2-1, tikulimbikitsidwa kuti musinthe mawonekedwe osungira m'njira zonse ziwiri.
Pakuwona kukonzekera kwa zosunga zobwezeretsera pazolinga zake - kubwezeretsa magwiridwe antchito - kusiyana kumapangidwa pakati pa zosunga "zotentha" ndi "zozizira". Zotentha zimasiyana ndi zozizira m'chinthu chimodzi chokha: zimakonzeka kugwiritsidwa ntchito nthawi yomweyo, pomwe zozizira zimafunikira njira zina zowonjezera kuti zibwezeretsedwe: kutulutsa, kutulutsa munkhokwe, ndi zina zambiri.
Osasokoneza makope otentha ndi ozizira ndi makope apaintaneti komanso opanda intaneti, zomwe zikutanthauza kudzipatula kwa data ndipo, kwenikweni, ndi chizindikiro china cha gulu la njira zosunga zobwezeretsera. Chifukwa chake kope lopanda intaneti - losalumikizidwa mwachindunji ndi dongosolo lomwe likufunika kubwezeretsedwanso - litha kukhala lotentha kapena lozizira (potengera kukonzekera kuchira). Kope la pa intaneti likhoza kupezeka mwachindunji komwe likufunika kubwezeretsedwa, ndipo nthawi zambiri kumakhala kotentha, koma palinso ozizira.
Kuphatikiza apo, musaiwale kuti kupanga makope osunga zobwezeretsera nthawi zambiri sikutha ndi kupanga kopi imodzi yosunga zobwezeretsera, ndipo pakhoza kukhala makope ambiri. Choncho, m'pofunika kusiyanitsa pakati pa zosunga zobwezeretsera zonse, i.e. omwe amatha kubwezeretsedwa mopanda zosunga zobwezeretsera zina, komanso kusiyanitsa (owonjezera, kusiyanitsa, kutsika, etc.) makope - omwe sangathe kubwezeretsedwa paokha ndipo amafuna kubwezeretsedwa koyambirira kwa zosunga zobwezeretsera chimodzi kapena zingapo.
Ma backups osiyanasiyana owonjezera ndikuyesa kusunga malo osungira. Chifukwa chake, data yokhayo yosinthidwa kuchokera ku zosunga zobwezeretsera zam'mbuyo imalembedwa ku kopi yosunga zobwezeretsera.
Zosiyana zochepetsera zimapangidwira cholinga chomwecho, koma mwanjira yosiyana pang'ono: kukopera kosunga kwathunthu kumapangidwa, koma kusiyana kokha pakati pa kope latsopano ndi lapitalo ndiko kumasungidwa.
Payokha, m'pofunika kuganizira njira zosunga zobwezeretsera kusungirako, zomwe zimathandizira kusakhalapo kosungirako zobwereza. Chifukwa chake, ngati mulemba zosunga zobwezeretsera zonse pamwamba pake, kusiyana kokha pakati pa zosunga zobwezeretsera kudzalembedwa, koma njira yobwezeretsa zosunga zobwezeretsera idzakhala yofanana ndi kubwezeretsa kuchokera pamakope athunthu komanso mowonekera.
Kodi kusunga ipsos custodes?
(Ndani adzalondera alonda okha? - lat.)
Ndizosasangalatsa kwambiri ngati palibe zosunga zobwezeretsera, koma ndizoyipa kwambiri ngati zosunga zobwezeretsera zikuwoneka kuti zapangidwa, koma pakubwezeretsa zimakhala kuti sizingabwezeretsedwe chifukwa:
- Kukhulupirika kwa gwero la data kwasokonekera.
- Zosungira zosunga zobwezeretsera zawonongeka.
- Kubwezeretsa kumagwira ntchito pang'onopang'ono; simungathe kugwiritsa ntchito data yomwe yabwezedwa pang'ono.
Ndondomeko yosunga zobwezeretsera yomangidwa bwino iyenera kuganizira ndemanga zotere, makamaka ziwiri zoyambirira.
Kukhulupirika kwa gwero la data kumatha kutsimikiziridwa m'njira zingapo. Zomwe zimagwiritsidwa ntchito kwambiri ndi izi: a) kupanga zithunzithunzi zamafayilo pamlingo wa block, b) "kuzizira" mawonekedwe a fayilo, c) chida chapadera chosungiramo mawonekedwe, d) kujambula motsatizana kwa mafayilo kapena midadada. Ma checksums amagwiritsidwanso ntchito kuonetsetsa kuti deta ikutsimikiziridwa panthawi yochira.
Kuwonongeka kosungirako kumatha kudziwikanso pogwiritsa ntchito macheke. Njira yowonjezera ndiyo kugwiritsa ntchito zipangizo zapadera kapena mafayilo amafayilo omwe deta yolembedwa kale singasinthidwe, koma zatsopano zikhoza kuwonjezeredwa.
Kufulumizitsa kuchira, kuchira kwa data kumagwiritsidwa ntchito ndi njira zingapo zobwezeretsera - pokhapokha ngati palibe chopinga mu mawonekedwe a netiweki wodekha kapena dongosolo la disk. Kuti muthane ndi vutoli ndi data yomwe yabwezeretsedwa pang'ono, mutha kuphwanya zosunga zobwezeretsera kukhala tinthu tating'onoting'ono, chilichonse chomwe chimachitidwa padera. Choncho, zimakhala zotheka kubwezeretsa ntchito nthawi zonse ndikulosera nthawi yochira. Vutoli nthawi zambiri limakhala mu ndege ya bungwe (SLA), kotero sitidzakhazikika pa izi mwatsatanetsatane.
Katswiri wa zokometsera si amene amaziwonjezera pa mbale iliyonse, koma amene sawonjezerapo china chilichonse.
