For developers at Universal Containers who need to build a high-performance report that displays Accounts opened in the past year grouped by industry, including information from contacts, opportunities, and orders, while dealing with several million Accounts, the two recommended options are:

B. Use triggers to populate denormalized related fields on the Account.

Populating denormalized fields on the Account object through triggers allows for the aggregation of relevant information from related entities (like contacts, opportunities, and orders) directly on the Account record. This approach can significantly improve report performance since it reduces the need for complex joins and calculations at runtime. By having the aggregated or summarized data readily available on the Account, the report can fetch this information more efficiently.

C. Use an indexed data field with bounded data filters.

Leveraging indexed fields in your report filters, such as using the Account creation date that is within the past year, helps ensure that the database queries are executed more efficiently. Indexed fields are optimized for faster search and retrieval operations. Bounded data filters, like specifying a date range for the past year, limit the scope of the data being queried, which can greatly enhance the performance of the report by reducing the amount of data that needs to be processed....
