Kudluliswa: ukuthi kuyini futhi kanjani it wadala

Isikhathi esining impela kuyi-Internet, ungase uhlangane eside ezifana "yokwehlukanisa". Kuyini futhi kungani udinga ukuba? Kuqondane ukuthi program ukunikeza umsebenzi Spars iyiphi isayithi. Noma umsebenzisi evamile ubhekene eside enjalo akazi ukubaluleka kwayo.

Uma sithatha Ngomqondo obanzi, le lokudlulisa - ukulandelana kwamagama uma iqhathaniswa imithetho komugqa ngolimi oluthile okungaba imuphi umuntu, esisetshenziswe ekuxhumaneni. It kungabuye ulimi semthethweni, ezifana ulimi lokwakha izinhlelo.

Futhi ngokuphathelene amasayithi ekuphenduleni umbuzo mayelana lokudlulisa - "kuyini lokho?", "Kungani ukusebenzisa" - kungashiwo ukuthi le nqubo ye lokudlulisa ezilandelanayo ulwazi lutholakala emakhasini wewebhu. Umbhalo lapha iqoqo idatha hierarchically ngaphambilini futhi olwakhiwe esebenzisa i-computer futhi ulimi lwabantu. Lesi sakamuva inikeza ukwaziswa okuqondile, okuyiwona abantu beze. Futhi izilimi izinhlelo ucacise indlela yokubonisa lolu idatha qapha yomsebenzisi.

Sesha okuqukethwe

Lapho umnikazi kudala indawo yakhe siqu kuphela, ebhekene nenkinga: lapho ukuze uthole okuqukethwe ukugcwalisa? Inketho engcono kakhulu ukucinga WAN. Phela, kukhona ngokungenamkhawulo eziningi ulwazi. Kodwa ke kukhona ezinye nobunzima:

• Njengoba i-intanethi sikhulela njalo nokuthuthukisa, kuyacaca ukuthi isayithi kufanele ibe oluningi ulwazi ukuze babe inzuzo phezu mncintiswano. Namuhla, okuqukethwe kumele kube kakhulu. A ngesandla ugcwalise nolwazi eziningi indawo kunzima kakhulu.
• Njengoba abantu abakwazi ukukhonza Indathane Imininingwane oshintshashintsha izidingo sokuhlaziya. Yini-ke nika? Automated Imininingwane ukuhlangana kanye nenqubo izinguquko.

elithola bohlahleli

Uhlelo okuyinto wenza inqubo yokuhlukanisa, uma iqhathaniswa nayo umuntu has eziningi eziwusizo:

• Masinyane lo dade wavula udabule izinkulungwane zamakhasi ewebhu.
• Ayikho inkinga ngeke ngedatha lobuchwepheshe kanye nolwazi kumuntu ofanele.
• Ngaphandle Iphutha ukulahla engadingekile, kusale kuphela lokho okudingekayo.
• Khiqiza ekufakeni idatha ezidingekayo ukuze uthole ukubuka umsebenzisi.

Yiqiniso, umphumela wokugcina isazodinga ezinye ukwelashwa. Akunandaba ukuthi isipredishithi noma imininingo egciniwe. Kodwa lokhu kulula kakhulu kunezinye uma ulifunda ngesandla, kunokuba usebenzisa yokuhlukanisa. Nalokho akwenzayo, kuyacaca - saving time nokuzikhandla.

design

izilimi ezihlukahlukene izinhlelo isetshenziselwe ukudala parsers. Okuvame kakhulu Izilimu zokubhala. Lokhu kusho ukuthi zilotshiwe iskripthi. Kuyini iskripthi futhi lokho yokwehlukanisa olwenziwa ngokusebenzisa ilimi elinjengokuthi ezocatshangelwa kamuva.

Ukudalwa bohlahleli hlelo akudingi ulwazi abalulekile ulimi lokwakha izinhlelo. Imininingwane Akuphoqelekile futhi eziyisisekelo mayelana nobuchwepheshe. Kodwa into ukwazi, kusadingeka. Ngakho, ukwazi ukuthi ukudala yokuhlukanisa, okungukuthi, analyzer hlelo, kudingeka ufunde lokhu okulandelayo:

• Ukuze kokuqala ukusebenza uhlelo algorithm idinga kokuhlaziya ikhodi yomthombo, amakhasi ewebhu, okuyinto ukunikela. Kukhona angikwazi ukwenza ngaphandle kolwazi okungenani isilinganiso ukuhlelwa ubuchwepheshe. Lokhu-HTML, CSS kanye ne-JavaScript ulimi.
• Ukuze ungene shí isihloko, kudingeka ufunde ubuchwepheshe ngokuthi DOM. Lokhu kusinikeza ithuba ukusebenza kakhulu ngempumelelo kusukela yokwehlayo khasi lewebhu.
• Isigaba nzima kakhulu - ubhala bohlahleli. Lapha kubalulekile ukuba ifa ithuluzi izocubungulwa umbhalo. program abanolwazi ngokuvamile zisebenzisa le njongo, izinkulumo njalo, okuyinto Kunamandla ngokwanele. Kodwa amandla akuyona kunjiniyela ngamunye. Lapha udinga engqondweni ekhethekile. Isixazululo elilungile liphakathi ukusebenzisa imitapo ngomumo eyenziwe adalwe ngqo yokuhlukanisa. Kuyini lokhu umtapo? It is igcwele ikhodi uhlelo, okuyinto vele iqukethe yonke imisebenzi ukuze ahlolwe.
• Kuyinto efiselekayo kakhulu ukuqonda izinhlelo into-ngamakhasimende, okusekelwa yiluphi ulimi izinhlelo.
• Isigaba sokugcina kuhilela ukuhlaziya imiphumela sicubungula idatha zenziwe futhi agcinwe. Kukhona angikwazi ukwenza ngaphandle nolwazi yolwazi.
• Sidinga ulwazi nokutholakala imisebenzi efanelekayo nokusebenza ngamafayela. Phela, idatha uzodinga ukubhala la mafayela ofanayo, bese, mhlawumbe, iguqulwe ibe ifomethi spreadsheet.

izigaba

Uma zonke izidingo zifeziwe, inqubo okwalandela zingahlukaniswa izigaba:

1. Esigabeni sokuqala we lokudlulisa uthole ikhodi yomthombo amakhasi ewebhu.
2. Isinyathelo esilandelayo - yokukhipha idatha ezidingekayo kusukela yomdwebo. Kukhona kulahliwe ikhodi ezingadingekile, ulwazi luhlelwa ngokuvumelana sabaphathi.
3. Ngemva idatha yimpumelelo kufanele agcinwe endaweni ifomu kungenziwa olunye kusetshenzwe.
4. Njengoba indawo akunalo ekhasini elilodwa, futhi kusukela isethi, algorithm kufanele bakwazi ukuhambisa ekhasini elilandelayo.

Ngakho, kudluliswa - kuyini? Lena inqubo ngokuhlaziya okuqukethwe kwesayithi ukuzihlalela ulwazi olufunayo. Ukusebenzisa ulwazi olungenhla, kungenzeka ukugcwalisa amasayithi abo eziningi okuqukethwe ngokuzenzekela. Lokhu kwenza kube nokwenzeka ukuthi iwine isikhathi uwine umncintiswano kulukhuni saytostroiteley emakethe.
