Data warehousing and data mining are continuously evolving because organizations generate huge volumes of data from business transactions, social media, websites, mobile applications, sensors and other digital sources. Emerging technologies such as cloud data warehouses, big data analytics, text mining, web mining and data stream mining have significantly improved the ability of organizations to collect, process and analyse data. These technologies strengthen Business Intelligence (BI) by providing faster, more accurate and comprehensive information for decision-making. Cloud data warehouses are one of the most important emerging trends. Unlike traditional data warehouses that require organizations to maintain physical servers, cloud data warehouses are hosted on cloud platforms. They provide flexible storage and computing capacity according to business requirements. Organizations can easily increase or decrease resources without making large investments in hardware. Cloud warehouses also support faster data integration, real-time access and collaboration among users located in different places. Examples include Snowflake, Google BigQuery, Amazon Redshift and Microsoft Azure Synapse. They enhance BI by allowing organizations to analyse large datasets quickly and economically. Big
