It is a crucial process in data warehousing and data integration that involves three main steps: • • Extract: Data is extracted from various source systems. These sources can include relational databases, flat files, web services, and other data repositories. The goal of the extraction phase is to gather data from all relevant sources into a staging area for further processing. • • Transform: Once extracted, the data undergoes transformation to convert it into a suitable format for analysis and reporting. • • Load: The final step is loading the transformed data into the target data warehouse or data mart. This process can be performed in batches (at scheduled intervals) or in real-time, depending on the requirements of the organization. The data is then ready for querying, analysis, and reporting. • 👉Subscribe to our new channel: / @varunainashots • ►Database Management System(Complete Playlist): • • DBMS (Database Management system) Com... • Other subject-wise playlist Links: • -------------------------------------------------------------------------------------------------------------------------------------- • ►Design and Analysis of algorithms (DAA): • • Design and Analysis of algorithms (DAA) • ►Computer Architecture (Complete Playlist): • • Computer Organization and Architectur... • ► Theory of Computation • • TOC(Theory of Computation) • ►Artificial Intelligence: • • Artificial Intelligence (Complete Pla... • ►Computer Networks (Complete Playlist): • • Computer Networks (Complete Playlist) • ►Operating System: • • Operating System (Complete Playlist) • ►Structured Query Language (SQL): • • Structured Query Language (SQL) • ►Discrete Mathematics: • • Discrete Mathematics • ►Compiler Design: • • Compiler Design (Complete Playlist) • ►Number System: • • Number system • ►Cloud Computing BIG Data: • • Cloud Computing BIG Data • ►Software Engineering: • • Software Engineering • ►Data Structure: • • Data Structure • ►Graph Theory: • • Graph Theory • ►Programming in C: • • C Programming • ►Digital Logic: • • Digital Logic (Complete Playlist) • --------------------------------------------------------------------------------------------------------------------------------------- • Our social media Links: • ► Subscribe to us on YouTube: / gatesmashers • ►Subscribe to our new channel: / @varunainashots • ► Like our page on Facebook: / gatesmashers • ► Follow us on Instagram: / gate.smashers • ► Follow us on Instagram: / varunainashots • ► Follow us on Telegram: https://t.me/gatesmashersofficial • ► Follow us on Threads: https://www.threads.net/@gate.smashers • -------------------------------------------------------------------------------------------------------------------------------------- • ►For Any Query, Suggestion or notes contribution: • Email us at: [email protected] • #etl#datawarehouse #datamining
