Abstract: Methods and systems for automatic table schema generation are disclosed. A description of a data source is received. A table definition is determined based on the description of the data source, wherein the table definition maps the data source to one or more columns of an output table. A parser for the data source is selected from a set of predefined parsers based on the description of the data source. A query against the data source is received. One or more elements of data responsive to the query are retrieved from the data source using the selected parser. The one or more elements are transformed into the output table based on the table definition.
