BuildColumnMetadata does 2 things: 1) Acts as the interface between information schema data stored in DuckDB and the parts of the application that will need to consume that data, in particular the model builder 2) Performs type validation against each column pulled from the source databases, via the Boyer-Moore majority voting algorithm.

BuildMetadata builds any required metadata for the sources in the sources.yaml config.

This is the main entry point for building models.

PrintPrettyJSON prints the pretty JSON to the console.

Retrieve data from sources and insert into the duckDB database.
