Скачать или смотреть ANALYTICAL THINKING #2 - Exploring Dimensions, Indicators, and Representation in OLAP

Welcome to Data By Design! In this episode of "Analytical Thinking," we dive deeper into the world of OLAP (On Line Analytical Process). Join us as we explore dimensions, indicators, and representation to enhance your analytical mindset.

Last time, we discussed the fundamental concepts of dimensions and indicators. Today, we'll delve into representation and granularity within the context of OLAP. We'll break down complex ideas into simple diagrams, making it easier to grasp the core concepts.

Discover how dimensions can be expressed as hierarchies, and learn to interpret symbols and numbers that indicate cardinalities. We'll use geographical and time hierarchies to illustrate these concepts visually.

Uncover the relationship between dimensions and measures. Using visual cues, we'll demonstrate how measures can be aggregated based on dimensions, leading to data-driven insights.

Please note that this conceptual representation sets the stage for future discussions on physical database modeling. Stay tuned for more in-depth explorations in upcoming videos.
