What are the key parameters for dimension groups of type: time?

• A. timeframes, sql, datatype, convert_tz
• B. timeframes, sql, dimension_type, aggregate_function
• C. sql, convert_tz, measure_type, dimension_group
• D. data_format, raw_field, timezones, sql

Answer: (A)

The key parameters for dimension groups of type time include timeframes, sql, datatype, and convert_tz. Timeframes are crucial as they define the levels of granularity you can analyze your time data, such as year, month, day, etc. This allows analysts to drill down or roll up their data based on temporal aspects. The sql parameter is essential because it dictates how the time data gets pulled from the database, ensuring that the correct field is referenced for date and time values. The datatype parameter is important as it informs Looker how to interpret the values in the time dimension, ensuring correct data handling and displaying. Lastly, the convert_tz parameter is significant for managing time zones by converting timestamps to the appropriate zones for accurate reporting and analysis. These components work together to create a comprehensive and flexible time dimension group in LookML, allowing users to perform time-based analyses effectively.
