Accelerating Reports with Materialized Views and Related Features

Materialized views and in-memory acceleration speed up repeated reporting queries without changing the report SQL. Materialized views define cached views that store persistent results to optimize queries that run often. BigQuery provides Smart Tuning materialized views that always return current data and also provide automatic query rewrite to materialized views even when the query refers to the base table. BI Engine is BigQuery's fast, in-memory analysis service for accelerating dashboards and interactive exploration.

1.A data analyst is writing a SQL query in BigQuery to analyze bike rental trends. The goal is to generate a report showing the average trip duration broken down by subscriber type and the starting hour of the day. The analyst writes the following query in BigQuery Studio: SELECT subscriber_type, EXTRACT(HOUR FROM start_time) AS hour_of_day, AVG(duration_minutes) AS avg_trip_length FROM bigquery-public-data.austin_bikeshare.bikeshare_trips When running the query, BigQuery returns an error indicating that subscriber_type is neither grouped nor aggregated. Which clause should the analyst append to the query to resolve the error and produce the desired summary report?
2.A data analyst needs to prepare a summary report in BigQuery that combines customer information with sales transactions. The database contains two tables: customers (columns: customer_id, customer_name) orders (columns: order_id, customer_id, order_amount) The analyst must produce a structured dataset showing each customer's name, the total number of orders placed, and their total spending across all transactions. Which SQL query should the analyst execute in BigQuery to generate this report?
3.A data analyst is tasked with generating a monthly revenue report by product category and geographic region from a multi-terabyte transactional dataset in BigQuery. The analyst needs to optimize the SQL query to minimize resource usage, reduce bytes scanned, and produce accurate summary aggregations. Which SQL querying practice should the analyst apply to achieve efficient query execution and accurate reporting?
