provide software, and users need to integrate software and hardware on their own. Although some products combine software and hardware, they are not specifically designed and optimized for data warehouses. These products require a very complex and long Manual Optimization process, and the subsequent maintenance costs are also very high. Netezza is a real all-in-one machine because it solves the above problems. It is a close combination of software and hardware that seamlessly integrates databas
