BigQuery のデータ変換ソリューションを設計しています。開発者は SOL に精通しており、ELT 開発手法を使用したいと考えています。さらに、開発者は直感的なコーディング環境と、SQL をコードとして管理する能力を必要としています。開発者がこれらのパイプラインを構築するためのソリューションを特定する必要があります。何をすべきでしょうか?
正解:C
To architect a data transformation solution for BigQuery that aligns with the ELT development technique and provides an intuitive coding environment for SQL-proficient developers, Dataform is an optimal choice. Here' s why:
* ELT Development Technique:
* ELT (Extract, Load, Transform) is a process where data is first extracted and loaded into a data warehouse, and then transformed using SQL queries. This is different from ETL, where data is transformed before being loaded into the data warehouse.
* BigQuery supports ELT, allowing developers to write SQL transformations directly in the data warehouse.
* Dataform:
* Dataformis a development environment designed specifically for data transformations in BigQuery and other SQL-based warehouses.
* It provides tools for managing SQL as code, including version control and collaborative development.
* Dataform integrates well with existing development workflows and supports scheduling and managing SQL-based data pipelines.
* Intuitive Coding Environment:
* Dataform offers an intuitive and user-friendly interface for writing and managing SQL queries.
* It includes features like SQLX, a SQL dialect that extends standard SQL with features for modularity and reusability, which simplifies the development of complex transformation logic.
* Managing SQL as Code:
* Dataform supports version control systems like Git, enabling developers to manage their SQL transformations as code.
* This allows for better collaboration, code reviews, and version tracking.
