Data Objects are the tables, views, methods, stored procedures, functions and custom SQL made accessible from the Data Sources for reports. This article applies to the Admin Console > Data > Objects settings.
Data Sources establish the connection between Exago and a database or a web service. Although typically only one database is used, Exago can join data from different sources into a single report.
Joins specify to Exago the relationship between Data Objects. This article applies to the Admin Console > Data > Joins settings, where joins are defined at the base-configuration level.
Parameters are used throughout the Exago application to store values. Although parameters can be created and given a default value in the Administration Console, parameters are designed to be set at runtime through the API.
