运行etl_pipeline()脚本并通过SQL Server Management Studio (SSMS)来更新数据库。 Github上的项目: https://github.com/PanosChatzi/FitnessDatabase 在运行完ETL管道后,你可以通过查询SQL Server里的_FitnessData_表来检查结果。 使用[myFitnessApp] SELECT DB_NAME() AS 当前数据库名称 SELECT * FROM [dbo]....
An ETL pipeline is a fundamental type of workflow in data engineering. The goal is to take data which might be unstructured or difficult to use and serve a source of clean, structured data. It is very easy to build a simple data pipeline as a python script. In this article, we tell y...
无论是临时的转换工作(ad-hoc),还是在给定的定时 pipeline 中进行复杂编排,dbt 都可以很好胜任。它的一大特色就是使用 SQL LIKE 语言去描述数据转换的规则。此外,它还基于 GitOps 可以非常优雅地多人协作、维护超大规模数据团队里复杂的数据处理作业。而 dbt 内置的数据测试能力可以很好地控制数据质量,可复现、控制...
