Final answer:
The efficiency comparison between summary indexing and report acceleration depends on the use case and requirements.
Step-by-step explanation:
The efficiency of summary indexing versus report acceleration depends on the specific use case and requirements. Summary indexing is a technique in which a summary index is created to store pre-aggregated data, allowing for faster searches and reports. On the other hand, report acceleration is a method that speeds up reporting by pre-calculating and caching results for frequently used reports.
In certain scenarios, summary indexing may be more efficient as it allows for real-time data analysis and faster searches. However, report acceleration may be more suitable when dealing with large datasets or complex queries that require extensive calculations.
Ultimately, the choice between summary indexing and report acceleration depends on the specific needs and goals of the system.
