or
a connection to a database.

an inzdf
object
a data.frame or db connection
the name of the data
additional arguments passed to methods
a list specifying the schema of the database (used for linking)
nested list of variables attributes for each table > variable
an inzdict object
if `TRUE` data will remain in DB (use for very large data)
TODO: It is possible to specify a linking structure between multiple datasets, and when variables are selected the dataset will be linked 'on-the-fly'. This, when used with databases, will significantly reduce the size of data in memory.
