SAP HANA
SAP HANA is an in-memory, column-oriented, relational database management system developed by SAP SE. It is designed for high-performance real-time analytics and applications, combining database, data processing, and application platform capabilities. It enables rapid data processing by storing data in RAM rather than on disk, supporting both transactional and analytical workloads.
Developers should learn SAP HANA when building enterprise applications that require real-time data processing, such as financial systems, supply chain management, or customer analytics, especially in SAP-centric environments. It is ideal for scenarios needing high-speed analytics, complex data modeling, and integration with other SAP products like SAP S/4HANA, as it reduces data latency and supports advanced features like predictive analytics and machine learning.
