Abstract: A method for automatically detecting the data type of data in a column includes receiving a request to import data into a base and determining the data type of the column by applying a set of inferrers to the column. In response to an inferrer returning true, the method selects the data type corresponding to the inferrer as the data type of the column and casts the data in the column to the selected type. A method for importing, converting, and presenting data based on data loss metrics includes receiving a request to import data into a database and determining data loss metrics for each of a set of data types. A user interface is configured to display some of the data types in conjunction with data loss metrics. The method further includes receiving a selection of one of the data types and casting the data to the selected type.
