Hi,
When you create and use Access 2010 style web databases, the data is all stored in SharePoint tables. Because of this, you automatically would get system fields such as Created By, Modified By, etc. Those system fields would automatically be filled in by the SharePoint authentication system.
Access 2013 and 2016 web apps, however are different. In the web apps, all data is stored in SQL tables. If you are on Office 365 the data is stored in SQL Azure tables. Besides that key difference compared to 2010 web databases, there is more of a separation from the data level and the UI level.
In Access web apps, the SQL tables don't have any context about who you are and therefore there is no concept of system fields like there are in 2010 web databases. One of the big reasons for the separation is that the data could be changed from any number of sources in like hybrid scenarios.
Does that answer your question?
