cdm_learn_from_db

A <code>src</code>-object on a DB or a connection to a DB.

dest

If there are any permament tables on a DB, a new <code><a rd-options="" href="/link/dm?package=dm&version=0.0.5.9000" data-mini-rdoc="dm::dm">dm</a></code> object can be created that contains those tables,
along with their primary and foreign key constraints.
Currently this only works with MSSQL and Postgres databases.
The default database schema will be used; it is currently not possible to parametrize the funcion with a specific database schema.

Provides tools for working with multiple related tables,
stored as data frames or in a relational database.
Multiple tables (data and metadata) are stored in a compound object,
which can then be manipulated with a pipe-friendly syntax.
