fsprojects/Rezoom.SQL
This system is a .NET-based SQL query compiler and type provider that generates strongly-typed, statically checked SQL code. It maps user-defined .NET types to database columns and supports multiple backends, including SQLite, PostgreSQL, and T-SQL. The framework provides a compile-time type provider for F# and runtime mapping utilities for C#, enabling safe and efficient database interactions.

How it got here
2016–2017 · Compiler overhaul and type provider expansion
This period focused on a major architectural shift, introducing a new Abstract Syntax Tree and type inference system within the SQL compiler. The team expanded the F# type provider to support multiple database backends (SQLite, Postgres, TSQL) and introduced configuration-driven connection management. Additionally, the project modernized its .NET targets and added comprehensive test suites and documentation for the new features.

2019–2026 · User type mapping and testing
This period focused on expanding support for user-defined types across multiple database backends, including T-SQL, PostgreSQL, and SQLite. The work involved implementing serialization and mapping logic for complex types like JSON, geography, and custom primitives, while simultaneously building out comprehensive test coverage and build automation for the type provider.

fsprojects/Rezoom.SQL was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit a4fabf1789 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
