[fpc-pascal]Common database access in Pascal

Could please send a complete example on this? The test and sample 
programs on the FCL provided by FPC 1.0.6 don't show this. I Could not 
figure, for example, how a Database and a Dataset would interact (I do 
not want each Dataset to have it's own connection to the database server).

By the way, have you seen my message about a possible memmory allocation 
bug on the DB classes from the FCL?
