#' Read data from 4D database
#'
#' This function is only useful for the MMB department of the UMCG. Use this function to \strong{import data by just defining the \code{file} parameter}. It will automatically transform birth dates and calculate patients age, translate the column names to English, transform the MO codes with \code{\link{as.mo}} and transform all antimicrobial columns with \code{\link{as.rsi}}.
#' @inheritParams utils::read.table
#' @param info a logical to indicate whether info about the import should be printed, defaults to \code{TRUE} in interactive sessions
#' @details Column names will be transformed, but the original column names are set as a "label" attribute and can be seen in e.g. RStudio Viewer.
#' @inheritSection AMR Read more on our website!
