Data Sources: Where your data comes from. Whether it is a database, cloud storage, API, FTP Server, etc. The data source is what you connect to in order for Nexla to scan your data.
Data Sets: Nexla automatically scans all of your data sources to identify different schemas to put them into data sets. Think of a data set as a table of attributes and their values.
Data Maps: Nexla has a lookup function that allows you to transform attributes based on a lookup table. Locate the lookup table within data maps. The data map allows you to define an alternate value for an attribute. For example, transforming an ID number to a text string.
