BCP vs SSIS

I have an application running on Unix that stores the information on
flat files. I want to be able to import all the data from some of those
files to SQL Server 2005 in order to create reports using reporting
services. After the initial import I want to be able to update (daily)
the tables on SQL Server with the changes to the flat files. What is
the more appropriate/easy tool for this scenario BCP or SSIS? Where I
can find information about how to create the "differential" import?I recommand to create a package and load the flatfile and use a conditionnal
split to filter this flow for a particular date (or another information like
a sequential ID stored in the flat file)
(but this required that you must read the entire source flat file)
or, maybe, you can start reading at a particular row the flatfile.
in the 2 cases you have to store anywhere the last reading position.
I don't know if you can, but another option is to truncate this flat file
after processing.
in this case every day the file will contain only new rows.
or if you can create 1 file by day you'll have the better way to load the
data in your hand!!!

BCP can only do the load part. SSIS can do the end-to-end process. SSIS can
FTP the files down from your Unix box, Load them into staging tables, and
run SQL to merge them into your production tables.
SSIS can also do more complicated data flows if you want to do perform the
merge and any data cleansing logic using an SSIS Data Flow task instead of
SQL Queries.
