Creative, mob siab rau thiab mob siab rau kev ua haujlwm yog ib qho tseem ceeb ntawm kev lag luam niaj hnub no. Txawm li cas los xij, kev muaj tswv yim yeej ib txwm cuam tshuam nrog cov nqi tsis tau pom dua ntawm lub sijhawm ua haujlwm, tsis paub tseeb hauv kev ntsuas kev ua haujlwm, qhov xav tau los qhia meej txog tus nqi ntawm kev ua haujlwm.

Muaj ntau txoj haujlwm uas tsis tas yuav muaj peev xwm ua tau zoo thiab tuaj yeem daws tau los ntawm qhov raug thiab ua tau zoo ua ntu ntawm cov haujlwm yooj yim. Daim ntawv txheeb xyuas tsuas yog ib qho kev xaiv los daws qhov teeb meem.

Scope ntawm lub tswv yim

Cov kev ua haujlwm yooj yim muaj ob qho tib si rau kev daws cov haujlwm tseem ceeb uas tau ua los ntawm cov kws tshaj lij uas tsim nyog, thiab rau lwm yam haujlwm uas cov neeg ua haujlwm zoo tib yam, cov tub ntxhais kawm lossis tub ntxhais kawm tuaj yeem ua tau.

Daim ntawv txheeb xyuas yog ib qho piv txwv ntawm qhov tseeb algorithm rau kev daws qhov teeb meem, sau ua ib ntu ntawm qhov yooj yim tshaj plaws, qhov tseeb tshaj plaws thiab meej, tab sis ua tiav cov yeeb yam uas yuav tsum tau ua, piv txwv li, mus rau:

• dav hlau tawm;
• mus raukhw thiab yuav yam niam nug;
• ua lag luam;
• ua tau qee lub hom phiaj;
• check lossis ua ib yam dab tsi.

Lub conveyor ib zaug tau hloov pauv kev lag luam, thiab nws tau los ua qhov tseem ceeb hauv kev tsim cov khoom tsis yog cov khoom yooj yim xwb, tab sis kuj siv cov tshuab, tshuab, khoom noj khoom haus, khoom ua si, khaub ncaws, khau.

Qhov zoo tshaj plaws, thaum daim ntawv txheeb xyuas yog kaum ob ntawm qhov tsim nyog tsawg kawg nkaus, ua haujlwm yooj yim:

• zoo tshaj plaws ua haujlwm yooj yim - ib qho yooj yim, unconditional hais kom ua ib yam dab tsi;
• qhia meej meej tsis tsim cov kev xaiv, tab sis qhov kev txiav txim tom ntej yog ua nruj me ntsis;
• tsis muaj kev txav mus los, txhua yam ua tiav nruj raws li txoj kev npaj thiab raws li cov ntsiab lus ntawm txhua yam ntawm daim ntawv.

Lub hom phiaj (ua haujlwm) tuaj yeem ua tau zoo, thiab tsis yog txhua qhov kev daws teeb meem tuaj yeem haum rau ntawm ib daim ntawv. Txawm li cas los xij, tsis muaj dab tsi tiv thaiv koj los ntawm kev tsim ntau daim ntawv txheeb xyuas uas tau ua tiav los ntawm cov neeg ua haujlwm sib txawv ntawm qee lub sijhawm.

phiaj xwm teeb meem

Kev npaj yog ib feem tseem ceeb ntawm kev lag luam. Daim ntawv txheeb xyuas kuj yog ib txoj kev npaj, tsis yog kev daws teeb meem xwb. Koj tuaj yeem tsim cov phiaj xwm kev nqis tes ua thaum muaj qhov xwm txheej tsis tau pom dua, ib txoj kev npaj ntawm tus cwj pwm thaum muaj xwm txheej lossis kev puas tsuaj ntuj tsim, kev ua haujlwm niaj hnub hauv cov menyuam yaus hnub so. Lub sijhawm ntawm cov chav kawm ntawm ib lub koom haum lossis tsev kawm ntawv kuj yog ib qho khoom siv rau "kev txawj ntse yooj yim", vim tias muaj cov xwm txheej hauv daim ntawv teev npe no. Piv txwv li, hnub los yog hnub khib, lub lis piam.

Txiv neejib txwm npaj txhua yam nws ua, tab sis nws ua tsis nco qab lawm. Qhov tshwm sim ntawm lub tswv yim ntawm "checklist" yog ib qho piv txwv ntawm yuav ua li cas qhov zoo tib yam thiab cwj pwm tsis nco qab nkag mus rau hauv lub peev xwm ntawm kev nco qab, tau txais lub ntsiab lus tshiab thiab qhov zoo nkauj tshiab.

Lo lus nws tus kheej kuj tseem hluas, tab sis keeb kwm ntawm nws lub tswv yim thiab nws daim ntawv thov rov qab mus ntau pua xyoo. Feem ntau yuav, thawj papyri nrog cov kev cai ntawm ib theem zuj zus ntawm tej yam yooj yim tau siv nyob rau hauv ancient sij hawm, txwv tsis pub nws yog ib qho nyuaj rau piav qhia lub sij hawm ntawm lub heyday ntawm ancient civilizations, raws li zoo raws li yog vim li cas rau lawv lub caij nplooj zeeg.

Sample: FTP daemon installation checklist

Nov yog tus qauv sau ib zaug thiab siv tau ntau xyoo. Tsis muaj dab tsi ntawm no yog tsim kom zoo nkauj, sau hauv Unixoid style, tab sis siv tau.

Feem ntau hais lus, cov ntawv txheeb xyuas no tau yug los ntawm kev tswj xyuas mus sij hawm ntev ua los ntawm tus thawj tswj hwm lub cev. Raws li txoj cai, tom qab ob lossis peb xyoos, tom qab ntau pua kev teeb tsa, tus thawj tswj hwm sau cov ntawv sau cia rau nws tus kheej thiab nws cov npoj yaig. Nov yog daim ntawv teev npe tiag tiag: dab tuag tab sis siv tau.

Sample of the beautiful impractical checklist

Tus sau ntawm cov khoom no ua haujlwm rau pej xeem. Outwardly, txhua yam yog lawm, tab sis qhov no tsis muaj txoj hauv kev ua rau lub xaib niaj hnub, tsim nyog, txhim khu kev qha thiab siv tau.

Txhua yam sau raug ntawm no, tab sis qhov no tsis yog daim ntawv teev npe. Tshwj xeeb, "Logo" yog cov lus qhia tshwj xeeb:

• create;
• yuav ua li cas;
• xav txog dab tsi;
• dab tsipov tseg.

Yuav tsum muaj ntau cov lus pom zoo tom qab txhua qhov lus qhia.

Kev thov txim rau cov lus hais yog qhov tsim nyog, tab sis tsim cov lus hais yog kev muaj tswv yim, thiab kuaj xyuas nws yog kev xyaum ua ntev (hauv Internet nyob tiag tiag nrog cov neeg tuaj saib coob heev), tsis siv rau daim ntawv txheeb xyuas.

Thiab rau txhua yam khoom.

Really "flying" checklist (fragment) for Boeing 737

Qhov no yog daim ntawv teev npe yuav tsum tau tsim. Ib kab lus yog ib lo lus teb yooj yim. Ntawd yog, ib qho yooj yim ua thiab qhov tshwm sim yooj yim.

Qhov no tsuas yog ib feem ntawm daim ntawv, thiab nws yog sau ua lus Askiv, tab sis qhov tshwj xeeb no, hom lus tsis tseem ceeb, tab sis qhov tseeb ntawm qhov kev tshaj tawm ntawm qhov kev txiav txim thiab tshuaj xyuas qhov tshwm sim ntawm nws qhov kev tua.

Test applications

Kev siv cov tswv yim ntawm txoj kev npaj ua tiav:

• sports;
• accounting;
• Tshuaj xyuas lub tuam txhab cov khoom;
• audit ntawm tuam txhab;
• ntsuas ntsuas;
• spaceship launch, thiab lwm yam.

Yuav luag txhua qhov chaw ntawm tus neeg lub neej thiab kev ua ub no tuaj yeem txhais tau los ntawm ntau yam ntawm cov phiaj xwm me me sib txawv: daim ntawv teev npe 1, 2, 3, thiab lwm yam.

Kev tswj hwm nruj ntawm kev ua yog qhov tseem ceeb tshwj xeeb hauv cov haujlwm tseem ceeb, piv txwv li, hauv kev npaj tus kws phais mob rau kev ua haujlwm, thaum cov neeg ua haujlwm kho mob, txhua tus kws kho mob thiab kws saib xyuas neeg mob koom nrog - txhua tus hauv lawv lub peev xwm - ua raws li kev tswj hwm nruj.npe ntawm kev ua. Feem ntau txhua yam ua tiav "ntawm lub tshuab", tab sis kev coj ncaj ncees yuav tsum tau ua txhua yam ua "ntawm ib daim ntawv".

Daim ntawv tshuaj xyuas yog ib daim ntawv pov thawj thiab kev tswj hwm ntawm kev tsim khoom thiab kuaj cov khoom noj khoom haus, cov khoom siv menyuam yaus, tshuaj xyuas cov tshuab ua haujlwm thiab cov txheej txheem.

Internet thev naus laus zis thiab kev ua haujlwm yooj yim

Txhua yam kev phais mob yuav tsum tau muaj tus kws phais mob uas tsim nyog. Tab sis nws kuj yuav tsum tau ua kom zoo ntawm kev ua haujlwm yooj yim. Tshwj xeeb, tag nrho cov cuab yeej ntawm lub rooj ua haujlwm yuav tsum dag nruj me ntsis hauv qee qhov chaw, tus neeg mob yuav tsum tau npaj rau kev ua haujlwm tsis yog lub cev nkaus xwb, tab sis kuj coj ncaj ncees.

Daim ntawv teev npe (ib qho piv txwv ntawm kev ua) tsis yog ib qho kev pab cuam, tsis yog ib qho algorithm, thiab nws yog ib qho nyuaj rau kev ntaus nqi nws rau kev ua haujlwm hauv kev nkag siab ntawm lo lus, tab sis Internet technologies tau coj mus rau qhov yuav tsum tau tsim. thiab ua haujlwm ntau yam, tab sis tseem ceeb heev.

Tsim ib lub vev xaib yuav tsum muaj tsawg kawg yog Apache, PHP thiab MySQL lossis nws qhov sib npaug raws li lwm tus neeg rau zaub mov, lwm tus neeg txhais lus thiab database. Txhim kho qhov trinity no yog qhov tsawg kawg nkaus uas yuav tsum tau ua kom meej meej ntawm kev ua.

Yuav yuam kev ntawm no yog fraught nrog impossibility ntawm kev ua haujlwm feem ntau. Niaj hnub nimno Internet programming yog characterized los ntawm qhov tseeb hais tias cov algorithms ntawm lub server, tus txhais lus thiab browser programming lus "tsis xav", tab sis yog hais tias lawv "tsis to taub" ib yam dab tsi, ces lawv yeej "tsis ua"!

Kev txiav txim yuam kev yuav tsum tau tshaj tawm, tab sis feem ntau cov ntawv sau rau hauv lub cav tsis txaus raukev daws teeb meem.

Internet programming: yooj yim daws teeb meem nyuaj

Daim ntawv tshuaj xyuas yog qhov kev daws teeb meem. Kev xyaum ntawm Internet programming nyob rau hauv JavaScript thiab PHP, tshwj xeeb, nrog rau cov khoom-oriented style ntawm kev sau ntawv, tso cai rau tsuas yog ob txoj kev los daws qhov teeb meem:

• kev txawj ntse.
• Test case.

Qhov thib peb tsis muab. Cov cuab yeej xeem hauv programming tau tsim los ntev heev. Kuj tseem muaj ntau yam cuab yeej ntxiv rau kev txheeb xyuas cov lej, thiab cov neeg tsim cov lus programming siv sijhawm ntau thiab siv zog los tsim kev debugging thiab nrhiav cov cuab yeej yuam kev.

Tab sis tsuas yog tus tsim (tus sau) ntawm cov cai, lossis cov ntaub ntawv ntsuas qib siab uas tsim los ntawm tus kws paub txog kev paub, tuaj yeem txiav txim siab nyob rau hauv qhov chaw twg, theem twg, nyob rau hauv qhov tshwj xeeb subsystem ntawm cov khoom ntawm cov txheej txheem dav dav.

Qhov kev daws teeb meem zoo tshaj plaws yog ua daim ntawv teev npe ntawm qib code, thaum tsis yog tus neeg, tab sis cov khoom tsim los ntawm nws saib xyuas kev ua tiav ntawm nws tus kheej ua haujlwm, thiab tseem tswj hwm nws lub xeev thiab nws kev sib raug zoo nrog lwm yam khoom..

nce qib hauv internet, SEO

Txij li thaum Internet tau dhau los rau cov pej xeem (thiab cov ncauj lus "cov ntawv txheeb xyuas raws li cov khoom lag luam sim" yeej ib txwm muaj rau cov neeg coob coob), cov kwj ntawm cov tswv yim monotonous tau ntws mus rau hauv SEO. Cov lus tsis tseem ceeb kiag li tau muab, thiab cov nyiaj tiag tiag raug nyem tawm ntawm cov neeg yuav khoom tsis txaus ntseeg ntawm qhov khoob thiab tsis muaj av.

Tus sau phau ntawv txheeb xyuas tau coj los ntawm buzzwords:

• kev tivthaiv;
• cov ntsiab lus sab hauv kev ua kom zoo;
• semantic cov ntsiab lus ntawm cov peev txheej tseem ceeb;
• ntsiab lus: nws yuav ua li cas thiab yuav ua li cas;
• sijhawm ua lag luam, kev siv nyiaj txiag;
• external xwm txheej;
• promotion region;
• lub sijhawm coj tus cwj pwm hauv daim duab ntawm tus qhua, thiab lwm yam.

Tab sis lub hom phiaj ntawm buzzwords yog nyiaj. Gullible buyers, them nyiaj rau "ua hauj lwm" ntawm cov sau phau ntawv checklists, stimulated zus tau tej cov xws li cov khoom, uas yog tsis zoo kiag li. Tab sis cov txheej txheem no tau ua rau lub ntsiab lus ntawm kev nce qib tau nthuav dav mus rau qhov siab tshaj plaws tau txwv thiab tsim cov xwm txheej rau kev nthuav dav ntawm cov ntaub ntawv.

Kev tsim tawm hauv cov ntaub ntawv xov xwm yog txheej txheem ntuj tsim, thiab niaj hnub no leej twg xav tau kev txhawb nqa tiag tiag ntawm lawv tus kheej cov peev txheej hauv txhua txoj kev:

• tus nqi tsawg, dhau ntawm tus kheej muaj peev xwm;
• tus nqi siab tshaj, dhau ntawm tus kws tshaj lij.

Daim ntawv txheeb xyuas hnub no yog qhov cuab yeej tiag tiag thiab ua haujlwm tau zoo rau kev ua tiav yam koj xav tau hauv nws txoj haujlwm raug cai thiab ua tiav kev ywj pheej nyob rau lub sijhawm muaj tswv yim ntawm lub hom phiaj ua tiav.

Virtual qhov chaw ntawm cov tswv yim yooj yim

Cov khoom siv hauv lub neej, tom haujlwm, hauv kev lag luam kev lag luam tag nrho tau txais kev ruaj ntseg. Cov laj thawj tseem ceeb rau kev ua tiav qhov kev xav tau tau dhau los ua qhov tseeb. Daim ntawv txheeb xyuas yog ib qho piv txwv ntawm yuav ua li cas cov khoom muaj tswv yim tau mus rau hauv qhov chaw virtual.

Qib kev txawj ntawm cov neeg siv khoom thiab cov tswv yim tsim tau hloov mus rautshiab zoo. Qhov no nullified txoj hauj lwm thiab coj mus rau tsim ib assortment ntawm cov hauj lwm tshiab thiab xav tau kev daws tshiab. Lub ntiaj teb tau dhau los ua qhov zoo dua qub dua, thiab rov ua qhov zoo dua qub yog vim qhov yooj yim thiab ntuj nqis rau pem hauv ntej.
