The data in all data sources are categorized into fields such as Customer, Sales, Profit, Temperature, etc. These fields are made from the columns in your data source. When you connect to a data source with Tableau, the fields are displayed along the left side of the workbook in the Data window. The fields are what you will use to build views of your data. Each field is automatically assigned a data type (such as integer, string, and date) and a pair of data roles.
