To help the people who use your hosted feature layers understand what each field stores, you should provide a useful, easy-to-read field display name, provide text to describe the purpose of each field, and define what type of data each field contains. Show As the owner of the hosted feature layer or an organization administrator, you add this information in the detailed view for each field. This information helps people decide if the data in the layer meets their needs, how best to apply styles to the layer, and gives editors the information they need to update or add attribute values. Set a display nameYou can change the field name that other users see when they view a hosted feature layer's attribute table. Set a display name that concisely conveys the field contents to help others understand the data. Changing the display name for a field does not affect the field name stored in the attribute table. Because it's a property of the field and not a field name, the display name can contain spaces and nonalphanumeric characters. To change the field name that others see when viewing the attribute table, follow these steps:
Provide a field descriptionThe field description helps you communicate what a field contains without having to use long or complicated field names. Add field descriptions from each field's detailed view on the Data tab of the hosted feature layer's item page.
When people use the layer in Map Viewer or Map Viewer Classic, they can access each field's description when setting the layer's style and when they open the table in the map. This information helps them understand how to use and symbolize the data. Define field value typesTo help users and client apps identify how field values should be used or represented, you can define what types of values are stored in each attribute field in your hosted feature layer. ArcGIS Online uses field value types to show you the most relevant options when drawing a layer in a map or configuring pop-ups. Field value typesThe following table lists each value type you can assign to a field and what each value type represents:
Add a field value typeField value types are also defined in each field's detailed view on the Data tab of the hosted feature layer's item page. Follow these steps to define field value types:
Map viewers set a default style based on the value type information to better represent the field's content. Feedback on this topic? What is data type of an attribute?Attribute data can be store as one of five different field types in a table or database: character, integer, floating, date, and BLOB. Character Data.
