Re: [IBO] Multiuser database access IBO example (source) need!

======================================================================
My classic program looks like this:



*DBConectionModul*
|
(TIB_Connection, TIB_Transaction)


*MainForm*



*CustomerForm* *CompanyForm* *Bank*
| | |
TIBquery+dataset TIBquery+dataset TIBquery+dataset


*AccountForm*
|
TIBquery+dataset(master)
|
TIBquery+dataset(detail)


I have only one TIB_Transaction...you sugest to put Transaction
component on each form in program?
Wich Isolation property you prefer?
Which TIB_Transaction common function I should use and when?
Which diferent is between Remote Desktop multiuser and remote database
multiuser enviroment?
