I have a question on which pattern to use. I have x number of input
files (XLS), which are merged, custom rules applied, magic pixie dust
applied then inserted into a database.
{ My syntax is off as I don't have the project in front of me }
So, should I do a)
foreach( string file in Directory.GetFiles("*.xls")
{
Register(new JoinOperationHere ( ).Left(new
ReadFileOperation(file).Right(new DatabaseModelRecords() ) );
)
}
Register ( new BusinessRulesOperation() );
Register( new WriteToDbOperation() );
...etc
or
b)
foreach( string file in Directory.GetFiles("*.xls")
{
Register(new JoinOperationHere ( ).Left(new
ReadFileOperation(file).Right(new DatabaseModelRecords() ) );
Register ( new BusinessRulesOperation() );
Register( new WriteToDbOperation() );
)
}
And, for bonus points, after you've done an aggregation, how would you
use that after the end of the EtlProcess to report the number of
records ?
Thanks. I really like this toolset. I've done what a previous team
took 2 months to do, in the past 3 days.
