Field notes

The project is organized around keeping a relational model tied to database reality rather than maintaining a manually edited image. Its described workflow includes reverse-engineering tables, columns, keys, indexes, and constraints, then comparing the result with production before a release. The page also separates physical and conceptual views for different roles, and points readers to a deployment guide, user guide, and public GitLab source repository.
