Hi,

How can we develop transaction based system like event management system in SharePoint 2013 online( Office 365 E3 version) and manage Transactions (like rollback, commit operation), data integrity, concurrent users update, Primary And foreign keys, Cascading deletes, Large data, Report from multi list. 

Any approach, information, code about this would be greatly appreciated. Thanks!
