9 -This Chapter brings together the different [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] constructs described in this User Guide into a coherent architecture that supports the typical [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] use cases shown above. The architecture described here shows how applications need not be concerned with the actual XML (or [[SDMX-EDI>>doc:sdmx:Glossary.SDMX-EDI.WebHome]]) or version of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]], but are concerned with interfaces offered by [[components>>doc:sdmx:Glossary.Component.WebHome]] that work with objects constructed according to the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]

22 -The [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Beans underpin the framework and are what may be referred to as ‘domain objects’, ‘data transfer objects’, or ‘business objects’.

24 24  Whilst “bean” objects can be created for a [[data set>>doc:sdmx:Glossary.Data set.WebHome]] or [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]], this does not scale well for large volumes of data/metadata. Therefore, the architecture shows a data streaming approach where the data/metadata are read or written directory to/from an input or output stream – this could be a local file or streamed over the internet.
