And, despite numerous alterations over the last five years in the arena of Big Data, cloud computing, predictive analysis, and information technologies, data warehouses have only gained more significance. Today, there are more possibilities available for storing, analyzing, and indexing data, but the importance of data warehousing cannot be denied. In this article, we will discuss basic concepts of data warehouse architecture, types, characteristics, and components of data warehouse modeling and design and see how they can help you build your data warehouse project.
