Something like Sphinx but for SQL, so we could document table structures and relationships in a series of web pages.
A colleague mentioned PostgreSQL Autodoc
This is a utility which will run through PostgreSQL system tables and returns HTML, DOT, and several styles of XML which describe the database.
As a result, documentation about a project can be generated quickly and be automatically updatable, yet have a quite professional look if you do some DSSSL/CSS work.
It allows specifying schemas and tables, and can even process comments on objects in different markup languages (e.g. markdown) using specified translating executables.
Amundsen is a data discovery and metadata engine for improving the productivity of data analysts, data scientists and engineers when interacting with data. It does that today by indexing data resources (tables, dashboards, streams, etc.) and powering a page-rank style search based on usage patterns (e.g. highly queried tables show up earlier than less queried tables). Think of it as Google search for data.
