13. Database Integration – Cont.
Goal – the Portal and the RTE remains different applications
Easy upgrade of any of the parts
Solution on database level – separate databases
Database integration is made by using only of triggers

14. Authentication/Authorization Integration
The RTE is running within the Portal – both shares one session
Authentication - only the login mechanism of the Portal is used
Authorization – the RTE authorization logic remains
23/02/2019

15. User Interface Integration
The Portal framework has strict UI policy – portlets
The RTE is running in a “iframe” portlet to keep its navigation logic untouched.
Most of the RTE administration functions are rewritten as separate portlet applications
