Hi all,
I have built a data access layer (DAL) and trying built a business logic layer (BLL). BLL will access DAL which in turn accesses the data layer (Database).
My question is that which is a better approach from the following?:
1. Have a property on the BLL class to maintain a reference to DAL. This reference will be used by methods when BLL communicates with the database.
2 Or pass DAL reference as a parameter to each public method that needs it.
Any pros or cons?
Any comments or suggestions or experience will be greatly appreciated!
TIA
