Flat Data Set
A flat dataset allows the retrieval of an entire table from a data source. In other words, it replaces a dummy query like select * from sales by automatically retrieving all rows in a table. To create a flat dataset, simply enter the table and the data source name. The below example
refers to the table inventory to retrieve the whole data.
