The field of data warehousing and analytics is constantly evolving, with new technologies and trends emerging all the time. Here are some of the most important emerging trends to watch in 2023 and beyond:
- Cloud data warehousing: Cloud data warehousing is on the rise, as more and more organizations are moving their data warehouses to the cloud. Cloud data warehousing offers a number of advantages over on-premises data warehousing, including scalability, flexibility, and cost-effectiveness.
- Data lakes: Data lakes are another emerging trend in data warehousing and analytics. Data lakes are central repositories of all types of data, including structured, semi-structured, and unstructured data. Data lakes can be used to store and analyze large amounts of data that would be difficult or impossible to store and analyze in a traditional data warehouse.
- Machine learning and artificial intelligence: Machine learning and artificial intelligence (AI) are being increasingly used in data warehousing and analytics. Machine learning and AI can be used to automate tasks, improve the accuracy of predictions, and develop new insights from data.
- Self-service analytics: Self-service analytics is a trend that is enabling business users to analyze data without the need for IT support. Self-service analytics tools are becoming more powerful and user-friendly, making them accessible to a wider range of users.
