Imethadatha - Iyini?

Kukhona yolwazi eminingi. Ukuze uqonde ukuthi ziyini, kubalulekile ukuba sicabangele okuqukethwe kwabo. Kodwa kukhona omunye imininingwane encane ewusizo - imethadatha. Yilokhu ifingqa lonke ulwazi olutholakala. Ngoba yikuphi babeklanyelwe futhi yini esetshenziswa?

Kuyini imethadatha?

Kufanele kuqashelwe ukuthi ukwakhiwa eyodwa lo mqondo akekho. Ngakho, imethadatha - lena igama elivamile ulwazi egciniwe. Ikakhulu esetshenziswa abizwa ezine ethemini:

1. Ingase isikisele Imininingwane subchannel mayelana idatha asetshenziswa.
2. Ngakho shayela izici ezichaza essence. Badinga ukubheka, ukukhomba, ahlolisise abuye ukulawula amanani database. Okuningi kangaka okuthiwa isethi ebalulekile kwenani elithile izincazelo olwakhiwe enikeziwe ngefomu eyamukelekayo futhi kufinyeleleke ngendlela ecacile, ngakho ungathola into oyifunayo. Lawa magama isetshenziswa Ezimweni lapho kubalulekile ukubheka essence, izinsiza kanye nezikhungo.
3. Idatha kusuka ku-uhlelo Imininingwane esisemthethweni ezichaza izakhiwo Igumbi lolwazi.
4. Ulwazi mayelana nezici ikhasi lewebhu (lapho, ngubani-ke sidalwe kombhali).

Umehluko phakathi idatha nemethadatha

Indlela uwahlukanise? Iqiniso lokuthi ngokwahlukana ocacile ngokuvamile akwenzeki. Kungani? Ake sihlolisise isibonelo:

1. Okuthile singenza kokubili izindima. Ngokwesibonelo, isihloko sihloko angabhekwa njengemihlatshelo isici imethadatha, njengoba ulwazi ezidluliselwa ngco kulofundzako.
2. Kungenzeka ukushintsha izindawo. Ake sithi othile wabhala umsebenzi senkondlo. Kuyinto idatha. Umqambi, sithembele amazwi, wadala komculo futhi unamathisele umbhalo. Kulokhu, it is ibe imethadatha. Konke kuncike ukusetshenziswa. Ngokuvamile, izimo ezinjalo kungenzeka kubangelwa bezibona iphuzu elithile umbono ngesisekelo ukwahlulela kwabo (lapha udlala indima zegama zohlelo kanye inkomba uhlelo).
3. Ukukwazi ukuqamba meta ... -metadannyh ukugxila Axiom lokuzikhethela. Lokhu kulandela kusukela lokuthi cishe zonke uhlelo Iwazi izici zayo siqu kungadalwa.

amafayela imethadatha amakhompyutha

Ukusebenzisa kwabo futhi abayitholile komsebenzi ezenzakalelayo. Uma uhlelo uyakwazi ukusebenza okuqukethwe isakhiwo idatha, bona zingaphendulwa zibe yizindawo yokuhlanganela olunye uhlobo kolwazi elikuvumela ukuba abasebenzisi mahhala kusuka izenzo ezihlukahlukene ungakhululekile nasendleleni enihlela ngayo izinto. Isibonelo ukuthuthukiswa, okuyinto ikuvumela ukubuka ihluzo ngezelulo ezahlukene. Ungase futhi khumbula ezahlukene umsindo orekhodiwe, amafilimu kanye nezinye izinto eziningi.

Imethadatha Inethiwekhi yomhlabajikelele

Kuyi-Internet nazo Kwenziwa ukuthola ulwazi oludingekayo ewusizo phakathi izindodla idatha. Kule umbono, imethadatha ukuthi owadalwa uhlangothi, kukhona ongowenani elikhulu ngenxa meaningfulness yayo. Njengoba lolu hlobo ulwazi ingaba njengesihluthulelo angukhiye, amamaki, eziningi nezinye izakhi. Imethadatha - wukuthi kafushane ekutshela mayelana nesayithi. Lapho ehlaziya izinjini sites ezimbalwa, uma kuzoveza kubo isihloko esifanayo amazwi ke inkomba lwabo ngomunye nomunye nomunye kuyoba ebaluleke ngaphezu amasayithi evamile.

ngezigaba imethadatha

Indlela uwahlukanise? Ngokuyinhloko, ngezigaba Kwenziwa omunye izimiso ezimbili:

1. Kokuqukethwe. Imethadatha isetshenziselwa ukuchaza ifayela, umthombo noma ekuqukethe (isibonelo, isihloko esithi - "indlela ukupheka amazambane").
2. Ngokusho izesekeli. Imethadatha ingasetshenziswa ukwazisa ngento iphelele noma iyingxenye. Ngakho, isihloko ifilimu libhekisela kubo bonke, futhi incazelo isiqephu yazisa kuphela inxenye ethile.

Uma imethadatha - iqoqo ukuncika inferencing amakhono, kuleso simo bahlukene zibe 3 izinhlobo:

1. idatha "Raw". Kubaluleka Information Security.
2. Imethadatha echaza okuqukethwe. Nazo ngokufanayo, nazo asetshenziswa.
3. Imethadatha engasetshenziswa ukwenza esiphethweni esinengqondo.

Lezi zinhlobo yemethadatha khona.

Abathathu ekilasini likufuna kakhulu

Sicela uthole amakilasi amathathu, manje esetshenziswa kabanzi:

1. imethadatha langaphakathi. Lolu lwazi echaza izingxenye ingxenye izinto, isakhiwo yabo nalokho elikumelelayo. Njengoba isibonelo, ubukhulu kanye ifayela format.
2. imethadatha yokuqondisa. Kuyadingeka ukucutshungulwa kolwazi, kanye ukuqokwa izinto. Ngokwesibonelo, ubani umbhali, umhleli, lapho ifayela yadalwa.
3. imethadatha okuchazayo. Zisetshenziswa elichaza uhlobo ifayela futhi izimfanelo zalo (isigaba osebenza ku yini enye ixhunywe).

imethadatha format

Ngakho ngokuthi standard, okuyinto kusetshenziselwa ukufeza incazelo esisemthethweni kwezinye izigaba kwezinsiza (izinhlangano, izinto kanye nokunye okufana nalokho).
Ngokuvamile it has a isethi ethile ephawula into okukhulunywa ngakho. Ngenxa yale njongo, izingxenye, izakhiwo, kanye izakhi imethadatha.
Oluthathwa by ububanzi futhi imininingwane imithombo kuchazwe.

izinkinga ezingase zibe khona

Lapho imethadatha singenzeka iphutha? Ukungabi kolwazi noma ukufinyelela Umkhawulo - lawa kwezimbangela eziyinhloko izinkinga. Futhi, iphutha imethadatha Ukulayisha kwenzeka ezimweni lapho ifayela, kodwa lilimele. Izizathu eziyinhloko kulolu isimo-akhawunti ye-ezintathu: ukugqoka imishini, umthelela elimazayo izinhlelo ngabanye (ngokuvamile zamagciwane) futhi ekupheleni engafanele idokhumenti, okwenza izazi idatha ezigcinwe kahle.

Ngakho, inani imethadatha ngezigaba kanye systematization kolwazi inethiwekhi ayikwazi overestimated. Ngakho-ke, ngifisa ukuba nokwandisa website yakho siqu nje kudinga ulwazi ngazo.
