'''Web data services''' refers to [[service-oriented architecture]] (SOA) applied to data sourced from the [[World Wide Web]] and the Internet as a whole. Web data services enable maximal mashup, reuse, and sharing of [[structured data]] (such as relational tables), semi-structured information (such as Extensible Markup Language (XML) documents), and [[unstructured information]] (such as [[RSS]] feeds, content from [[Web applications]], commercial data from online business sources).
'''Web data services''' is a class of [[data]], information, [[RSS]] feeds and content from the [[world wide web]], [[web applications]] and online business sources. Web data services<ref>InfoWorld (June 22, 2009), [http://www.infoworld.com/d/developer-world/kapow-focuses-web-data-services-600 Kapow Focuses on Web Data Services.]</ref> form a fast-growing addition to [[structured data]], [[unstructured data]] and traditional online content.

To speed development of Web data services, enterprises can deploy technologies that ease discovery, extraction, movement, transformation, cleansing, normalization, joining, consolidation, access, and presentation of disparate information types from diverse internal sources (such as data warehouses and [[customer relationship management]] (CRM) systems) and external sources (such as commercial market data aggregators). Web data services build on industry-standard protocols, interfaces, formats, and integration patterns, such as those used for SOA, Web 2.0, Web-Oriented Architecture, and [[Representational State Transfer]] (REST). In addition to operating over the public Internet, Web data services may run solely within corporate intranets, or across B2B supply chains, or even span hosted software-as-a-service ([[SaaS]]) or [[Cloud computing]] environments.<ref>[http://hinchcliffe.org/archive/2008/02/27/16617.aspx What Is WOA?

To use and inter-relate web data services, technologies have been designed to speed the finding, downloading, cleaning<ref>Kapow Technologies [http://kapowtech.com/index.php/products/kapow-web-data-server Web Data Server.]</ref>, and integrating of the content so it can be readily used and presented, either alone or in combinations.<ref>Microsoft Developer Network [http://msdn.microsoft.com/en-us/data/bb931106.aspx ADO.NET Data Services.]</ref> Increasingly, such content from a wide variety of sources will be used to broaden the scope, power, and applicability of business intelligence, [[data warehousing]] and trend analytics of many kinds. Most forms of web data services are built and delivered on and via common [[web standards]] and protocols.
The web data services category continues to grown in popularity as organizations increasingly seek to monitor and use data from myriad public and private web sites -- from such news sources as [[CNN]], for example, to social networking sites such as [[Facebook]], as well as from business ecosystem partners, private web applications and across [[supply chains]]. Web data services also comprise certain inputs and outputs from [[web services]] integrations, [[cloud computing]] services, [[software-as-a-service]] applications, and service-oriented and web oriented architecture<ref>[http://hinchcliffe.org/archive/2008/02/27/16617.aspx What Is WOA? It's The Future of Service-Oriented Architecture (SOA)]</ref> applications. Web data services are also commonly used to expedite the process of migrating content from one [[content management]] system to another.
