ETL Nedir?<\/h2>\n\n\n\n
ETL, verilerin kaynaktan hedef depoya aktar\u0131lmas\u0131 s\u00fcrecini ifade eder. Extract<\/strong>, Transform<\/strong> ve Load<\/strong> kelimelerinin k\u0131saltmas\u0131d\u0131r. Veriler \u00f6ncelikle mevcut kaynaklardan \u00e7\u0131kar\u0131l\u0131r ve bu veriler daha sonra istenen formata d\u00f6n\u00fc\u015ft\u00fcr\u00fcl\u00fcr ve ard\u0131ndan daha fazla analiz i\u00e7in depoya y\u00fcklenir. ETL s\u00fcreci, geli\u015ftiriciler, analistler, test uzmanlar\u0131, \u00fcst d\u00fczey y\u00f6neticiler de dahil olmak \u00fczere \u00e7e\u015fitli payda\u015flardan aktif girdiler gerektirir ve teknik olarak zordur.\u00a0<\/p>\n\n\n\n
ETL Pipeline Nedir? <\/h2>\n\n\n\n
ETL pipeline, \u00e7e\u015fitli kaynaklardan verileri alan, gerekli formata d\u00f6n\u00fc\u015ft\u00fcren ve bir hedef veri taban\u0131na veya veri ambar\u0131na y\u00fckleyen s\u00fcre\u00e7ler toplulu\u011fudur. Bir ETL pipeline olu\u015fturmak, verileri bir konumdan di\u011ferine ta\u015f\u0131mak i\u00e7in belirli bir s\u0131rayla at\u0131lan bir dizi ad\u0131md\u0131r. ETL pipeline b\u00fcy\u00fck miktarda veriyi verimli bir \u015fekilde i\u015flemek i\u00e7in tasarlanm\u0131\u015ft\u0131r.<\/p>\n\n\n\n
ETL Pipeline Mimarisi <\/h2>\n\n\n\n
<\/figure><\/div>\n\n\n\n
Bir ETL pipeline mimarisi genellikle \u00fc\u00e7 ana bile\u015fenden olu\u015fur: kaynak sistem, d\u00f6n\u00fc\u015ft\u00fcrme motoru ve hedef sistem.<\/p>\n\n\n\n
Kaynak Sistem:<\/strong> Kaynak sistem veri kayna\u011f\u0131d\u0131r. Veri tabanlar\u0131, dosyalar, API’ler ve bulut hizmetleri dahil olmak \u00fczere veri olu\u015fturan herhangi bir sistem olabilir. Kaynak veriler, d\u00f6n\u00fc\u015f\u00fcm motorunun kullanabilece\u011fi bir formatta bu sistemden al\u0131nmal\u0131d\u0131r.<\/li>
D\u00f6n\u00fc\u015f\u00fcm Motoru:<\/strong> ETL pipeline\u2019\u0131n verileri i\u015fledi\u011fi yerdir. Bu bile\u015fen, verilerin temizlenmesinden, d\u00f6n\u00fc\u015ft\u00fcr\u00fclmesinden ve hedef sisteme y\u00fcklenebilecek bir formatta derlenmesinden sorumludur. D\u00f6n\u00fc\u015f\u00fcm motorlar\u0131 \u00e7e\u015fitli programlama dilleri, \u00e7er\u00e7eveler ve ara\u00e7lar kullan\u0131larak olu\u015fturulabilir.<\/li>
Hedef Sistem:<\/strong> De\u011fi\u015fiklik verilerinin y\u00fcklendi\u011fi hedef sistemdir. B\u00fcy\u00fck miktarda veriyi i\u015fleyebilen bir veri taban\u0131 veya veri ambar\u0131 olabilir. Hedef sistem, veri de\u011fi\u015fikliklerini kolayca analiz etmek ve g\u00f6rselle\u015ftirmek i\u00e7in sorgular ve raporlar i\u00e7in optimize edilmelidir.<\/li><\/ul>\n\n\n\n
Bu mimarinin temel avantajlar\u0131ndan biri, \u015firketlerin verileri analiz etmek i\u00e7in farkl\u0131 kaynaklardan gelen verileri entegre etmelerine olanak sa\u011flamas\u0131d\u0131r. Bu, i\u015fletmelerin eksiksiz ve do\u011fru bir veri g\u00f6r\u00fcn\u00fcm\u00fcne dayal\u0131 olarak daha iyi kararlar almas\u0131na yard\u0131mc\u0131 olabilir.<\/p>\n\n\n\n
ETL T\u00fcrleri <\/h2>\n\n\n\n
ETL (Extract, Transform, Produce) pipeline, verileri kaynak sistemden hedef sisteme kullan\u0131labilir ve de\u011ferli bir formata d\u00f6n\u00fc\u015ft\u00fcrerek aktarmak i\u00e7in kullan\u0131l\u0131r. A\u015fa\u011f\u0131dakiler de dahil olmak \u00fczere \u00e7e\u015fitli ETL t\u00fcrleri vard\u0131r:<\/p>\n\n\n\n
1. Toplu ETL Pipeline<\/h3>\n\n\n\n
Bir toplu ETL i\u015flem hatt\u0131nda veriler kaynak sistemden \u00e7\u0131kar\u0131l\u0131r, uygun formata d\u00f6n\u00fc\u015ft\u00fcr\u00fcl\u00fcr ve hedef sisteme toplu olarak y\u00fcklenir. Toplu ETL i\u015flem hatlar\u0131, g\u00fcnl\u00fck veya haftal\u0131k bir programa g\u00f6re i\u015flenebilen b\u00fcy\u00fck miktarda veriyi i\u015flemek i\u00e7in kullan\u0131\u015fl\u0131d\u0131r.<\/p>\n\n\n\n
Ger\u00e7ek zamanl\u0131 ETL ard\u0131\u015f\u0131k d\u00fczeninde veriler kaynak sistemden ger\u00e7ek veya de\u011fi\u015fime yak\u0131n bir \u015fekilde elde edilir ve ard\u0131ndan hemen hedef sisteme y\u00fcklenir. Ger\u00e7ek ETL pipeline, verileri h\u0131zl\u0131 bir \u015fekilde i\u015flemeniz ve analiz etmeniz gerekti\u011finde kullan\u0131\u015fl\u0131d\u0131r ve veri ETL pipeline olarak da adland\u0131r\u0131l\u0131r.<\/p>\n\n\n\n

Art\u0131ml\u0131 ETL i\u015flem hatt\u0131, b\u00fcy\u00fck miktarda veri oldu\u011funda ve veri kayna\u011f\u0131nda s\u0131k s\u0131k de\u011fi\u015fiklik yap\u0131ld\u0131\u011f\u0131nda kullan\u0131\u015fl\u0131d\u0131r.<\/p>\n\n\n\n
4. Hibrit ETL Pipeline<\/h3>\n\n\n\n
Hibrit ETL i\u015flem hatlar\u0131 toplu ve ger\u00e7ek zamanl\u0131 i\u015flemeyi birle\u015ftirir. Hibrit bir ETL i\u015flem hatt\u0131nda veriler d\u00fczenli aral\u0131klarla ve kritik veriler mevcut oldu\u011funda ger\u00e7ek zamanl\u0131 olarak i\u015flenir. Bu t\u00fcr bir ETL i\u015flem hatt\u0131, verileri h\u0131zl\u0131 bir \u015fekilde i\u015flemeniz gerekti\u011finde kullan\u0131\u015fl\u0131d\u0131r.<\/p>\n\n\n\n
5. Bulut ETL Pipeline<\/h3>\n\n\n\n

Bir bulut ETL i\u015flem hatt\u0131nda, bulut tabanl\u0131 ara\u00e7lar ve hizmetler kullanarak kaynak sistemlerden hedef sistemlere veri ay\u0131klar, d\u00f6n\u00fc\u015ft\u00fcr\u00fcr ve y\u00fcklersiniz. Bulut ETL ard\u0131\u015f\u0131k d\u00fczenleri, bulutta depolanan verileri i\u015flemeniz gerekti\u011finde veya bulut tabanl\u0131 ara\u00e7 ve hizmetlerin \u00f6l\u00e7e\u011finden ve esnekli\u011finden yararlanmak istedi\u011finizde kullan\u0131\u015fl\u0131d\u0131r. <\/p>\n\n\n\n
Bir ETL olu\u015fturmak birka\u00e7 ad\u0131mdan olu\u015fur:<\/p>\n\n\n\n
1. Kapsam\u0131 ve gereksinimleri tan\u0131mlay\u0131n<\/h3>\n\n\n\n
\u00c7\u0131kar\u0131lacak, de\u011fi\u015ftirilecek ve y\u00fcklenecek verilerin yan\u0131 s\u0131ra veri u\u00e7 noktalar\u0131n\u0131 tan\u0131mlay\u0131n. Kaynak sistemleri ve veri kalitesi, veri hacmi veya uyumluluk sorunlar\u0131 gibi potansiyel sorunlar\u0131 belirleyin.<\/p>\n\n\n\n
2. Verileri ay\u0131klay\u0131n<\/h3>\n\n\n\n
Kaynak sistemden gerekli verileri ay\u0131klar. Bu API, SQL sorgular\u0131n\u0131n veya di\u011fer veri madencili\u011fi ara\u00e7lar\u0131n\u0131n kullan\u0131lmas\u0131n\u0131 i\u00e7erebilir.<\/p>\n\n\n\n
3. Veri manip\u00fclasyonu<\/h3>\n\n\n\n
\u00c7\u0131kar\u0131lan veriler analiz veya depolama i\u00e7in uygun bir formatta olmayabilir. Nihai hedefe haz\u0131rlamak i\u00e7in verileri temizleyerek, filtreleyerek, birle\u015ftirerek ve konsolide ederek d\u00f6n\u00fc\u015ft\u00fcrmeniz gerekir.<\/p>\n\n\n\n
4. Veri y\u00fckleme<\/h3>\n\n\n\n
De\u011fi\u015ftirilmi\u015f verilerin bir u\u00e7 nokta dosya depolama sistemine y\u00fcklenmesidir. Bu, tablolar veya \u015femalar olu\u015fturmay\u0131, e\u015fleme alanlar\u0131n\u0131 ve verileri do\u011frulamay\u0131 ve hatalar\u0131 ele almay\u0131 i\u00e7erebilir.<\/p>\n\n\n\n
5. Pipeline\u2019\u0131 test edin ve izleyin<\/h3>\n\n\n\n
ETL i\u015flem hatt\u0131 kurulduktan sonra, beklendi\u011fi gibi \u00e7al\u0131\u015ft\u0131\u011f\u0131ndan emin olmak i\u00e7in iyice test etmek \u00f6nemlidir. \u00c7al\u0131\u015fma s\u0131ras\u0131nda olu\u015fabilecek hatalar\u0131 veya sorunlar\u0131 tespit etmek ve \u00e7\u00f6zmek i\u00e7in izleme ve uyar\u0131 s\u00fcreci olu\u015fturun.<\/p>\n\n\n\n
