Abstract
Šajā darbā tiek aprakstīts viens no nozīmīgākajiem Oracle datu noliktavas procesiem. ETL process datu noliktavās sastāda līdz pat 80% no visas datu noliktavas izveides laika un tiek uzskatīts par pašu nozīmīgāko. Darbā tiek apskatīts, kādi ir ETL posmi un kādas darbības tie sevī ietver, kā arī veikta reālu ETL procesu analīze.
In this paper I have described one of the major processes of Oracle data warehouse. ETL process in data warehouse occupies 80% of all development's time and it is taken as main process. In this paper I have discussed about chapters of ETL and operations of these chapters and done analysis of real ETL processes.
