Business Objects
In Workday data is stored in business objects like organizations, workers, or positions.
Like in the Excel sheet we have columns and rows, a business object has fields and instances. Each instance is like a row. A Worker business object is like a Worker excel or spreadsheet, but instead of having a row for each worker, you have an instance for each worker.
A Business Object may have 0,1 or many instances and workday will decide how the business objects are related and link between them.
We will talk more about Data sources,PBO and RBO in the post Reports in workday.
