5 == 1.1 Scope of the User Guide ==
6
7 This Guide covers all of the major use cases for [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] from simple data reporting to a completely self-updating web dissemination system of data and related [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]]. The use cases show how best to take advantage of the [[SDMX Information Model>>doc:sdmx:Glossary.SDMX Information Model.WebHome]] in statistical systems in order to manage data and metadata reporting, data and metadata storage and retrieval, and data and metadata dissemination.
8
9 The principal intention is help organizations and individuals to determine how best to use [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] in order to help them to improve the statistical production process. In order to achieve this objective, examples are taken from real implementation scenarios that enable the reader to understand the scope of the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] standards and guidelines in terms of the activities required in order to collect, process, and publish statistical data and [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]].
10
11 The guide is concerned principally with the reporting/collection, processing, and dissemination of aggregated statistical data. Clearly a large part of the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] standard is technical in nature but the audience for this guide is anyone who is involved in the processes that eventually result in the publishing of statistical data either internally within the organization or externally to interested parties. Whether the dissemination is internal or external, this is achieved more and more using web-based technologies, for which [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is ideally suited.
12
13 The [[SDMX Information Model>>doc:sdmx:Glossary.SDMX Information Model.WebHome]] is pivotal to implementation of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] and systems built with knowledge of this Information Model are easy to maintain, enable data and metadata sharing both between internal systems and with the systems used by the organizations that collect data and metadata, and enable access directly the databases and [[metadata repositories>>doc:sdmx:Glossary.Metadata repository.WebHome]] of data and metadata producers.
14
15 There is a growing availability of software tools, many of them free of charge or open source, that support many of the aspects of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]. Use of these tools or of the underlying [[components>>doc:sdmx:Glossary.Component.WebHome]] of the tools can reduce dramatically the cost, internal resources, and the elapsed time of the development of a new system or the integration of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] into an existing system.
