Modelling for Data Warehouse

Overview

Data modelling for a data warehouse is the process of designing the structure and relationships of data entities within a data warehouse environment. It involves creating a conceptual, logical, and physical representation of the data to support efficient data storage, retrieval, and analysis.
The data modelling process begins with a thorough understanding of the business requirements and objectives of the data warehouse. This includes identifying the key data entities, their relationships, and the desired analytical outcomes.
Data modelling process going through Conceptual, Logical and Physical phase and understanding business requirements and how to identify dimensions and facts, as One of the key steps in data modelling for a data warehouse where dimensions represent the descriptive attributes used for analysis, while facts are the numeric measures or metrics that provide the basis for analysis.

By the end of the workshop, participants will have a solid understanding of data modelling concepts and different techniques such as Dimensional modelling or Data Vault, and will have created a data model based on a sample business case.
