What data can be reviewed through the _SYS_STATISTICS schema in SAP HANA?

• A. Historical data
• B. User data
• C. Performance data
• D. Backup data

Answer: (C)

The _SYS_STATISTICS schema in SAP HANA is specifically designed to store performance-related data. This schema provides a comprehensive view of various aspects of the system's performance metrics, which can help administrators and developers monitor and analyze how well the system is functioning. The data within this schema can include information such as resource utilization, execution times for queries, and other relevant statistics that aid in optimizing the performance of the database. Performance data is essential for identifying bottlenecks, understanding workload characteristics, and making informed decisions about system configurations or query optimizations. By reviewing this data, users can gain valuable insights into the efficiency of their HANA environment and take necessary actions to enhance performance. The other options refer to different types of data that are not specifically encompassed by the _SYS_STATISTICS schema. Historical data typically pertains to past data records, user data relates to information specific to database users and applications, and backup data involves stored copies of database instances for recovery, none of which fall under the scope of the performance-oriented statistics held in the _SYS_STATISTICS schema.
