Vrstva sb\u011bru a p\u0159\u00edjmu dat<\/h3>\n

Vrstva p\u0159\u00edjmu zachycuje data z v\u00edce zdroj\u016f v re\u00e1ln\u00e9m \u010dase nebo v d\u00e1vkov\u00fdch intervalech. Modern\u00ed podniky generuj\u00ed data p\u0159es r\u016fznorod\u00e9 syst\u00e9my: transak\u010dn\u00ed datab\u00e1ze, cloudov\u00e9 aplikace, IoT za\u0159\u00edzen\u00ed, API, soubory protokol\u016f a senzory. Vrstva p\u0159\u00edjmu mus\u00ed pojmout tuto rozmanitost a z\u00e1rove\u0148 zajistit kvalitu dat u zdroje.<\/p>\n

Tok dat:<\/strong>\u00a0Mapujte, jak data proud\u00ed ze zdroj\u016f p\u0159es p\u0159\u00edjem, \u00falo\u017ei\u0161t\u011b, transformaci a anal\u00fdzy. Identifikujte \u00fazk\u00e1 m\u00edsta a jednotliv\u00e9 body selh\u00e1n\u00ed. Navrhujte pro odolnost a \u0161k\u00e1lovatelnost.<\/p>\n

P\u0159\u00edstup integrace:<\/strong>\u00a0Rozhodn\u011bte se mezi ETL (transformace p\u0159ed na\u010dten\u00edm) a ELT (na\u010dten\u00ed pak transformace). Pro cloudov\u00e1 \u0159e\u0161en\u00ed s elastick\u00fdm zpracov\u00e1n\u00edm ELT \u010dasto poskytuje flexibilitu.

Navrhujte pro \u0161ifrov\u00e1n\u00ed, kontrolu p\u0159\u00edstupu, audit logging a monitoring compliance. Bezpe\u010dnost, kter\u00e1 je pozd\u011bji p\u0159id\u00e1na, je drah\u00e1 a \u010dasto ne\u00fapln\u00e1.<\/p>\n
