These last days I had the dubious pleasure of setting up an integrated Crystal Reports xi solution. Reporting is certainly one of the less glamorous but more crucial aspects of corporate computing. This was a simple RPT to PDF converter, yet the compiled distributable clocked in at a hefty 70 MB, mostly due to the dreaded merge modules (a 150+ MB separate download; at least they seem to have fixed the annoying KeyCode bug). Not to mention that in order to get it to work with Visual Studio 2005 I had to download a Release 2 – 2 downloads of 700 and 300 MB, respectively.
Clearly, this is unacceptable. MS Reporting Services all of a sudden makes sense although that is no walk in the park either.
Most of CR’s (now, Business Objects) heft comes from, I think, the fact that it covers the entire processing workflow – connecting to data, parsing the data streams, rendering the results. It connects to a dizzying array of data sources and it may have its own internal query processor for all I can tell. In fact, there would be a nice architectural solution to this if one considers that reporting is really just the basic processing of a firehose data stream. If vendors could come up with and agree on an ODBC-type of interface, the life of report tool creators (and of programmer users) would be so much easier. Everything that Crystal connects to today, for example, could be a data store supporting a ‘reporting’ interface. Querying the data store via this interface (if binary objects can describe their supported methods via IUnknown, certainly data can describe its own structure!) would result in a XML output that could be ideally be streamed directly to a XAML visual layer.
It would be nice.
