How is 'Airflow' pronounced?
Airflow is pronounced /ˈɛərfloʊ/ — 'AIR-floh'. It is a compound of 'Air' + 'Flow'. 'Air' = /ɛər/ (the vowel in 'there', 'care', 'fair'). 'Flow' = /floʊ/ (diphthong as in 'go', 'show'). Two syllables: AIR-floh, stress on the first. The name evokes the smooth flow of tasks through a pipeline, like air through a system. Apache Airflow is a platform for programmatically authoring, scheduling, and monitoring data workflows using directed acyclic graphs (DAGs).

How is 'Dagster' pronounced?
Dagster is pronounced /ˈdæɡstər/ — 'DAG-stur'. The name derives from 'DAG' (Directed Acyclic Graph) + '-ster' (an agent suffix as in 'gangster', 'hipster'). 'DAG' = /dæɡ/ — short /æ/ as in 'bag', 'lag'. '-ster' = /stər/ (schwa). Two syllables: DAG-stur, stress on the first. Dagster is a data orchestration platform for the development, production, and observation of data assets, emphasising software-engineering best practices for data pipelines.

How is 'Prefect' pronounced?
Prefect is pronounced /ˈpriːfɛkt/ — 'PREE-fekt'. The English word 'prefect' (a senior student or official appointed to oversee others) conveys the tool's role of overseeing and orchestrating data pipelines. 'Pre' = /priː/ (long 'ee', the prefix meaning 'before' or 'chief'). 'fect' = /fɛkt/ (short /ɛ/ + /kt/ cluster). Two syllables: PREE-fekt, stress on the first. Prefect is a modern workflow orchestration tool for data engineering, designed to handle failures gracefully with a focus on developer experience.

How is 'dbt' pronounced?
dbt (data build tool) is pronounced /diː biː tiː/ — 'DEE BEE TEE'. Each letter is spelled out: d = /diː/, b = /biː/, t = /tiː/. Despite the lowercase branding and the temptation to say 'DEBT' or 'DIB-it', the community universally spells it out as individual letters. In conversation: 'DEE BEE TEE'. dbt is a transformation workflow tool that enables data analysts and engineers to write modular SQL transformations, test them, and document them, operating within the modern data stack.

How is 'Trino' pronounced?
Trino is pronounced /ˈtriːnoʊ/ — 'TREE-noh'. The name was chosen when the project (formerly known as Presto) was renamed to Trino in 2021. It has no specific etymological meaning but follows the pattern of Italian/Latin-sounding tech names. 'Tri' = /triː/ (long 'ee'). 'no' = /noʊ/ (diphthong /oʊ/). Two syllables: TREE-noh, stress on the first. Trino is a distributed SQL query engine designed to query large datasets across multiple data sources, formerly known as PrestoSQL.
