Data Warehouse & Data Mining - Lec - 21: Concept Hierarchy, Categorization & Computation | Data Warehouse

Concept hierarchy in a data warehouse refers to the process of organizing data into multiple levels of abstraction, enabling easier analysis and reporting. It helps in summarizing and drilling down data to gain insights at various granularities. In this video, we will explore how concept hierarchies are used to enhance data analysis and decision-making in a data warehouse. -------------------------------------------------------------------------------------------------------------------------------------- Timestamps: 00:00 - Introduction 00:33 - What is Concept Hierarchy? 00:54 - Example of Concept Hierarchy 04:55 - What are Measures 05:10 - What are types of Measures? 05:44 - Example of Measures -------------------------------------------------------------------------------------------------------------------------------------- 🔹 Gate Smashers Shorts: Watch quick concepts & short videos here: https://www.youtube.com/@GateSmashersShorts 🔹 Subscribe for more shorts and motivational content: https://www.youtube.com/@varunainashots Subject-wise playlist Links: -------------------------------------------------------------------------------------------------------------------------------------- ►Design and Analysis of algorithms (DAA): https://www.youtube.com/playlist?list=PLxCzCOWd7aiHcmS4i14bI0VrMbZTUvlTa ►Software Engineering (Complete Playlist): https://www.youtube.com/playlist?list=PLxCzCOWd7aiEed7SKZBnC6ypFDWYLRvB2 ►Database Management System: https://www.youtube.com/playlist?list=PLxCzCOWd7aiFAN6I8CuViBuCdJgiOkT2Y ►Cloud Computing: https://www.youtube.com/playlist?list=PLxCzCOWd7aiHRHVUtR-O52MsrdUSrzuy4 ► Theory of Computation https://www.youtube.com/playlist?list=PLxCzCOWd7aiFM9Lj5G9G_76adtyb4ef7i ►Artificial Intelligence: https://www.youtube.com/playlist?list=PLxCzCOWd7aiHGhOHV-nwb0HR5US5GFKFI ►Computer Networks (Complete Playlist): https://www.youtube.com/playlist?list=PLxCzCOWd7aiGFBD2-2joCpWOLUrDLvVV_ ►Operating System: https://www.youtube.com/playlist?list=PLxCzCOWd7aiGz9donHRrE9I3Mwn6XdP8p ►Structured Query Language (SQL): https://www.youtube.com/playlist?list=PLxCzCOWd7aiHqU4HKL7-SITyuSIcD93id ►Discrete Mathematics: https://www.youtube.com/playlist?list=PLxCzCOWd7aiH2wwES9vPWsEL6ipTaUSl3 ►Compiler Design: https://www.youtube.com/playlist?list=PLxCzCOWd7aiEKtKSIHYusizkESC42diyc ►Number System: https://www.youtube.com/playlist?list=PLxCzCOWd7aiFOet6KEEqDff1aXEGLdUzn ►Programming in C : https://www.youtube.com/playlist?list=PLxCzCOWd7aiGmiGl_DOuRMJYG8tOVuapB ►Data Structure: https://www.youtube.com/playlist?list=PLxCzCOWd7aiEwaANNt3OqJPVIxwp2ebiT ►Computer Architecture : https://www.youtube.com/playlist?list=PLxCzCOWd7aiHMonh3G6QNKq53C6oNXGrX ►Graph Theory (Complete Playlist): https://www.youtube.com/playlist?list=PLxCzCOWd7aiG0M5FqjyoqB20Edk0tyzVt ►Digital Logic: https://www.youtube.com/playlist?list=PLxCzCOWd7aiGmXg4NoX6R31AsC5LeCPHe --------------------------------------------------------------------------------------------------------------------------------------- Our social media Links: ► Subscribe to us on YouTube: https://www.youtube.com/gatesmashers ►Subscribe to our new channel: https://www.youtube.com/@varunainashots ► Like our page on Facebook: https://www.facebook.com/gatesmashers ► Follow us on Instagram: https://www.instagram.com/gate.smashers ► Follow us on Instagram: https://www.instagram.com/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]
