Subsetting
Deredza marekodhi kuti ugadzire diki, inomiririra chikamu chedhatabhesi rehukama uchichengetedza kutendeseka
Nhanganyaya Subsetting
Chii chinonzi subsetting?
Kuderedza huwandu hwemarekodhi kuti ugadzire diki inomiririra dhatabhesi rine hukama nereferensi yakachengetedzwa.
Sei masangano achishandisa subsetting?
Masangano mazhinji ane nharaunda dzekugadzira dzine huwandu hukuru hwe data uye haadi huwandu hukuru hwe data munzvimbo dzisiri dzekugadzira bvunzo. Nekudaro, kuseta kwedatabase kunoshandiswa kugadzira diki, inomiririra subset yehombe rehukama dhatabhesi ine yakachengetedzwa referensi kuperera. Masangano anoshandisa sub-setting yekuyedza data kuderedza mutengo, kuita kuti igone kurongeka uye nekukurumidza kuseta nekugadzirisa.
Deredza zvivakwa uye mutengo wekuverenga
Yakawandisa data mavhoriyamu anogona kutungamira kune yakakwira zvivakwa uye mutengo wekuverenga, izvo zvisingakodzeri kune bvunzo data munzvimbo dzisiri dzekugadzira. Nekugona kuseta, unogona kugadzira madiki madiki e data rako kuti uderedze mutengo wako.
Zvinogoneka kuyedza data nevaongorori nevagadziri
Kugadzirisa mavhoriyamu makuru edata munzvimbo dzisiri dzekugadzira zvinounza matambudziko kune vanoedza uye vanogadzira. Idiki uye nekudaro inokwenenzveka bvunzo data, zvakanyanya kukwenenzvera kuyedza nekuvandudza maitiro, pakupedzisira optimize kutenderera kwese maererano nenguva nezviwanikwa.
Inokurumidza kuyedza data kuseta uye kugadzirisa
Madiki data mavhoriyamu anofambisa nekukurumidza uye nyore kuseta uye kugadzirisa kweasina-kugadzira bvunzo nharaunda. Izvi zvinonyanya kukosha munzvimbo dzakaoma dzeIT uye kana shanduko dzinowanzoitika muzvimiro zvedata zvinoda kugadziridzwa nguva dzose uye kuzorodza kuti ive nechokwadi chekumiririrwa kwedata rekuyedza.
Chii chinonzi referential integrity uye nei ichikosha?
Referential kutendeseka ipfungwa mune dhatabhesi manejimendi iyo inovimbisa kuenderana uye kurongeka pakati pematafura mune yehukama dhatabhesi. Referential kutendeseka kwaizove nechokwadi chekuti kukosha kwese kunoenderana ne "Munhu 1" we "Tafura 1" inoenderana nehukoshi hwechokwadi hwe "munhu 1" mu "Tafura 2" uye chero imwe tafura yakabatana.
Kusimbisa kutendeseka kwakakosha pakuchengetedza kuvimbika kwedata rekuyedza mune dhatabhesi rehukama sechikamu chenzvimbo dzisiri dzekugadzira. Inodzivirira kusawirirana kwedata uye inova nechokwadi chekuti hukama pakati pematafura hune zvahunoreva uye hwakavimbika pakuyedzwa kwakakodzera uye kugadzirwa kwesoftware.
Yedza data mune yehukama dhatabhesi nharaunda inofanirwa kuchengetedza referensi yekutendeseka kuti ishandiswe. Kuchengetedza kutendeseka munzvimbo dzisiri dzekugadzira, dzakadai sedziya dzinoshandiswa kuyedza nekuvandudza software, kwakakosha nekuda kwezvikonzero zvakati:
Kuisa pasi, kwete nyore se "kungodzima data"
Subsetting haisi nyore sekungodzima data, sezvo ese ari pasi nepamusoro ane hukama akabatana matafura anofanirwa kunge ari kuseta zvakaenzana kuchengetedza referensi. Subsetting inovimbisa kuti kwete chete data mutafura inotangwa inobviswa, asi zvakare kuti chero data mune chero imwe tafura yakabatana ine chekuita neiyo data yakabviswa kubva patafura inotangwa inobviswa. Izvi zvinova nechokwadi chekuti kurevera kutendeseka pamatafura, dhatabhesi uye masisitimu anochengetedzwa sechikamu chekudzima data.
Kuderedza vhoriyamu yedata nekubvisa "Munhu X" kubva "Tafura Y", zvinyorwa zvose zvine chokuita ne "Munhu X" mu "Table Y" inofanira kubviswa, asiwo zvinyorwa zvose zvine chokuita ne "Munhu X" mune chero imwe tafura yepamusoro kana pasi pemvura (tafura A, B, C nezvimwewo) inofanirawo kubviswa.
Kuderedza huwandu hwe data nekubvisa "Richard" kubva patafura ye "Vatengi"., marekodhi ese ane chekuita na“Richard” ari mu”Mutengi” tafura anofanirwa kudzimwa, asiwo marekodhi ese ane chekuita na“Richard” mune chero imwe tafura yekumusoro kana yakadzika inoenderana (Payment table, Incidents table, Insurance Coverage Table etc.) deleted.

Proportional subsetting
Iwe unogona kugadzirisa iyo Syntho Injini yekuseta dhatabhesi rehukama uye kuve nechokwadi chekuti "matafura akabatanidzwa" akaiswa pasi zvichienderana ne "Target Tafura".
- Tafura yechinangwa: Vashandisi vanogona kutsanangura tafura inotangwa senzvimbo yekutanga yekuseta.
- Vashandisi vanogona semuenzaniso kutsanangura kuisa "Patient Tafura" kune 5% kana ku500k marekodhi panzvimbo ye10.000k zvinyorwa.
- Matafura akabatanidzwa: Aya ese akabatana kana zvisina kunanga matafura kune "Target Tafura". Zvinongedzo pakati pematafura zvinogona kunge zvakanangana, senge tafura inotangwa inodudza allergies iyo inoreva tafura yevarwere kuburikidza nehukama hwehukama hwekunze, kana isina kunanga, senge tafura yakanangwa inoreva tafura yevarwere, iyo inozoreva tafura yechipatara.
- Subsetting inovimbisa kuti marekodhi ese ane chekuita neiyo data yakadzimwa mu "Patient Table" ichabviswawo. Mumuenzaniso, subsetting inovimbisa kuti mune chero "Yakabatanidzwa Tafura" pane chete data ine hukama ne5% (500k recors) uye kuti mamwe ese data ane chekuita ne95% (10.000k - 500k = 9.500k marekodhi) anobviswa. kugadzira chikamu chidiki chinomiririra chedatabase ine hukama hwakachengetedzwa hwakachengetedzwa
Subsetting yakavakirwa pamitemo yebhizinesi
Kuwedzera kune proportional subsetting, apo iwe unotsanangura chikamu chekutora data, hunyanzvi hwedu hwepamberi hunokutendera kuti unyatso kutsanangura boka rinonangwa rekuseta. Semuenzaniso, unogona kudoma maitiro ekusanganisa kana kusabvisa chaiwo maseti, achipa kuchinjika kukuru uye kutonga pamusoro pemaitiro ekubvisa data.
