Data Lineage . Cov ntaub ntawv kab tuaj yeem txhais raws li lub neej voj voog thiab xaus rau qhov kawg ntws cov ntaub ntawv . Cov ntaub ntawv kab enables cov tuam txhab lag luam mus taug qab qhov chaw ntawm kev lag luam tshwj xeeb cov ntaub ntawv , uas ua rau lawv taug qab qhov yuam kev, siv cov kev hloov pauv hauv cov txheej txheem, thiab siv qhov system tsiv teb tsaws kom txuag tau qhov tseem ceeb ntawm lub sijhawm.
Yog li ntawd, dab tsi yog txhais los ntawm cov ntaub ntawv kab?
Cov ntaub ntawv kab feem ntau yog txhais ua ib yam cov ntaub ntawv lub neej voj voog uas suav nrog cov ntaub ntawv keeb kwm thiab qhov twg nws txav mus rau lub sijhawm. Lub sij hawm no kuj tau piav ua li cas rau cov ntaub ntawv raws li nws mus los ntawm ntau yam txheej txheem.
Kuj Paub, vim li cas cov ntaub ntawv kab ntawv tseem ceeb? Kawg, tab sis tsis tsawg tshaj plaws, cov ntaub ntawv kab yog tseem ceeb vim o cov ntaub ntawv rau feem ntau lub koom haum hloov pauv txhua xyoo. Yog li, thaum lub lag luam tau txais kev pom rau cov ntaub ntawv kab , nws muaj peev xwm nyob twj ywm tshiab nrog kev hloov cov ntaub ntawv ib puag ncig uas muaj kev cuam tshuam ntau rau nws txoj haujlwm thiab tuaj yeem xyaum cov ntaub ntawv kev tswj hwm.
Dab tsi yog data lineage hauv kev tswj hwm cov ntaub ntawv?
Cov ntaub ntawv kab yog lub capture ntawm ntws cov ntaub ntawv los ntawm qhov chaw los ntawm intermediary systems thiab cov ntaub ntawv kev hloov pauv mus rau qhov chaw kawg lossis cov neeg siv khoom. Kab mob system flow diagrams muab kev pom ntawm qhov ntws ntawm cov tshuab txhawb nqa kev lag luam lossis cov ntaub ntawv kev xa khoom.
Qhov pov thawj ntawm cov ntaub ntawv yog dab tsi?
Lub sij hawm cov ntaub ntawv pov thawj ” hais txog ib txoj kev taug uas suav txog keeb kwm ntawm ib daim cov ntaub ntawv (nyob rau hauv ib lub database, ntaub ntawv los yog repository) ua ke nrog ib tug piav qhia ntawm yuav ua li cas thiab yog vim li cas nws tau mus rau qhov chaw tam sim no. A pov thawj cov ntaub ntawv yuav khaws cov keeb kwm no rau txhua daim cov ntaub ntawv.

Cov ntaub ntawv hloov pauv yog cov ntaub ntawv uas tau tsim nyob rau hauv daim ntawv thov kev sib ntsib, uas tsis tau khaws cia hauv cov ntaub ntawv tom qab daim ntawv thov raug txiav
Dab tsi yog kev noj cov ntaub ntawv hauv cov ntaub ntawv loj?
Cov ntaub ntawv ingestion yog tus txheej txheem ntawm tau txais thiab import cov ntaub ntawv rau tam sim ntawd siv los yog cia nyob rau hauv ib tug database. Txhawm rau noj ib yam dab tsi yog 'coj ib yam dab tsi los yog nqus ib yam dab tsi.' Cov ntaub ntawv tuaj yeem xa tawm hauv lub sijhawm tiag tiag lossis noj hauv cov khoom siv
Dab tsi yog cov ntaub ntawv thev naus laus zis hauv kev tswj cov ntaub ntawv xov xwm?
Kev tswj cov ntaub ntawv xov xwm (MIS) yog hais txog cov txheej txheem loj siv los ntawm kev lag luam lossis kev lag luam, thaum cov ntaub ntawv thev naus laus zis (IT) yog ib feem ntawm cov txheej txheem uas siv los sau thiab xa cov ntaub ntawv.

Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
