Declaration
TIB_Database = class(TIB_Connection)

Description
This component is intended for BDE/VCL compatibility only. It is a TIB_Connection descendant that is outfitted with its own internally contained TIB_TransactionDefault component. This welds the two together such that there is only one transaction for the connection.

Any statement or dataset that attaches to this via. the IB_Connection property will automatically have their IB_Transaction propety assigned to the internally contained IB_TransactionSingle instance.

Thus, all transaction control is bound at the connection level instead of taking advantage of InterBase's capability of having multiple transactions per connection.

This could lend some simplicity to your application if you do not want to have to worry about making sure each dataset has its IB_Transaction property properly assigned.

If an IB_Transaction property is left blank and its IB_Connection property is not a TIB_Database class then the statement, dataset, etc. will create its own internal transaction. This could cause an undesirable effect of having different statements and datasets being kept within different transaction contexts.

It is extra work to use the IB_Connection and IB_Transaction components separately but the flexibility and functionality it gives to your application makes it worth it to avoid using the TIB_Database class.
