該DSV文件擴展名是用來在文件中也被稱為數據源視圖文件,這類文件通常與Microsoft SQL Server,微軟的軟件是用來存儲數據庫(數據庫管理系統)相關聯。其中一個微軟的SQL服務器的主要功能是保存和所要求的軟件應用程序中檢索數據,它可以在同一台計算機或那些連接的網絡上的計算機上使用。數據源視圖文件(DSV)是已在微軟SQL Server 2005引入的一個新概念。 DSV文件是建立在一個數據源,所以為了讓你使用一個數據源視圖在包中,你需要先添加數據源中的包。文件類型,如DSV和類似使然如何在數據源中的微軟SQL服務器來看,它給出了一個具體的選擇數據庫對象的介紹了Microsoft SQL Server 2005中的Microsoft SQL Server 2008和Microsoft SQL Server 2008的S2的來源和目的地。
SQL Server 2008, formerly codenamed Katmai, was released on August 6, 2008 and goals to make data self organizing, management self-tuning, and self maintaining with the improvement of SQL Server Always On technologies, to give almost-zero downtime. SQL Server 2008 also includes support for structured and semi-structured data, as well as digital media formats for pictures, audio, video and other multimedia data. In present versions, such multimedia data can be saved as BLOBs (binary large objects), but they are generic bit streams. It also natively supports hierarchical data, and includes T-SQL constructs to directly deal with them, without using recursive queries. Basic awareness of multimedia data will permit specialized functions to be performed on them. According to Paul Flessner, senior Vice President, Server Applications, Microsoft Corp., SQL Server 2008 can be a data storage backend for different varieties of data: XML, email, time/calendar, file, document, spatial, etc as well as perform search, query, analysis, sharing, and synchronization across all data types.
SQL Server 2005, formerly codenamed Yukon, was released in October 2005. It’s a built-in native support for managing XML data and adding relational data. Purposely, it defined an XML data type that could be utilized either as literals in queries a data type or in database columns. XML columns can be linked with XSD schemas; XML data being saved is verified against the schema. XML is changed to an internal binary data type before being saved in the database. Specialized indexing methods were made available for XML data. XML data is inquired using XQuery; SQL Server 2005 added some extensions to the T-SQL language to permit embedding XQuery queries in T-SQL. In addition, it also defines a new extension to XQuery, called XML DML that allows query-based modifications to XML data. SQL Server 2005 also allows a database server to be exposed over Web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests. When the data is viewed over Web services, results are returned as XML.
