Cov ntaub ntawv engineers yog zoo li cov uas tsis tau paub txog tus phab ej cov ntaub ntawv ntiaj teb. Lawv txoj haujlwm yog qhov nyuaj heev, suav nrog cov txuj ci tshiab thiab thev naus laus zis tshiab. Nws yog tiag nyuaj los tsim ETL pipelines tshiab." "Nws yog ntau dua nyuaj tshaj li ib txwm software engineering txoj hauj lwm.
Ua raws li qhov kev pom no, Data Engineering puas yog txoj haujlwm zoo?
Ua ib data engineers Cov ntaub ntawv engineers tau ua haujlwm nrog kev tshawb nrhiav cov ntaub ntawv thiab tsim cov software tsim nyog. Cov ntaub ntawv engineers nrhiav tau lub hauv paus rau lawv hauj lwm thaum lawv kawm computer science, nrog majors hauv software engineering thiab cov ntaub ntawv kev loj hlob yog tshwj xeeb yog pab tau.
Ib sab saum toj no, kuv tuaj yeem dhau los ua Data Engineer li cas? Rau ua ib tug data engineer , koj yuav tsum muaj keeb kwm hauv computer science, engineering , lej lossis muaj degree hauv ib qho kev kawm txog IT. Txij li thaum txoj haujlwm ua haujlwm yuav tsum muaj kev nkag siab zoo hauv kev paub txuj ci, tsuas yog los ntawm kev txais daim ntawv pov thawj yuav tsis txiav qhov kev sib tw.
Yog li ntawd, nws yuav siv sijhawm ntev npaum li cas los ua tus kws tsim cov ntaub ntawv?
Kauj Ruam Ib: Tau txais daim bachelor's Degree (Four Years) Tom qab kawm tiav high school, aspiring cov ntaub ntawv engineers yuav tsum tau kawm tiav bachelor's degree, zoo tshaj plaws hauv computer science.
Dab tsi yog cov txuj ci uas xav tau rau cov ntaub ntawv engineer?
Nov yog ob peb yam txuj ci tseem ceeb uas xav tau los ntawm cov ntaub ntawv engineers
- Cov cuab yeej thiab Cheebtsam ntawm Cov Ntaub Ntawv Architecture.
- Kev paub tob txog SQL thiab lwm yam kev daws teeb meem Database.
- Cov ntaub ntawv khaws cia thiab ETL cov cuab yeej.
- Hadoop-Based Analytics (HBase, Hive, MapReduce, thiab lwm yam)
- Coding.
- Machine Learning.
- Ntau yam kev khiav haujlwm.

Vim li cas cov ntaub ntawv tiaj tus tsis zoo dua li cov ntaub ntawv sib raug zoo?
Ib lub rooj ua ntaub ntawv tiaj tus yog qhov tseem ceeb rau kev sau cov ntaub ntawv tsawg. Tab sis cov ntaub ntawv loj loj tuaj yeem ua tsis tau raws li nws siv ntau qhov chaw thiab nco dua li cov ntaub ntawv sib txheeb. Nws kuj yuav tsum tau muab cov ntaub ntawv tshiab ntxiv txhua zaus koj nkag mus rau cov ntaub ntawv tshiab, qhov kev sib raug zoo database tsis
Kuv yuav hloov cov ntaub ntawv tab delimited rau cov ntaub ntawv csv li cas?
Mus rau cov ntawv qhia zaub mov, xaiv 'OpenCSVTab-Delimited File' (lossis tsuas yog nias Ctrl + O), thiab tom qab ntawd los ntawm lub thawv qhib, xaiv cov ntaub ntawv tab-delimited qhib. Koj tuaj yeem luam cov tab-delimited txoj hlua mus rau clipboard thiab tom qab ntawd siv 'Qhib Cov Ntawv Hauv Cov Ntawv Teev Npe' xaiv (Ctrl + F7)
Ntev npaum li cas cov ntaub ntawv tuaj yeem khaws cia hauv cov ntaub ntawv warehouse?
10 xyoo Yog li ntawd, cov ntaub ntawv khaws cia hauv lub tsev khaws ntaub ntawv li cas? Cov ntaub ntawv yog feem ntau khaws cia rau hauv ib lub tsev khaws ntaub ntawv los ntawm cov txheej txheem rho tawm, hloov pauv thiab thauj khoom (ETL), qhov twg cov ntaub ntawv tau muab rho tawm los ntawm qhov chaw, hloov mus rau qhov zoo cov ntaub ntawv thiab ces loaded rau hauv ib lub tsev khaws khoom .
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
