Semantic constraint based xml updating
Dr Jixue Liu's research and teaching areas are mainly in database and data mining areas.His research topics are in XML, dependency theory and discovery, privacy, text and sequence data analytics, data integration and entity resolution.Schematron is simple and easy to use but has a number of shortcomings: CLi X is a constraint language based on first order logic.It was first specified in 1998, when XML was not yet ubiquitous, in research at University College London.Uses a blank space as the identifer of rows ( SELECT constraint_id ,convert(XML, ('') xmldoc FROM @tmp Constraint ) AS a CROSS APPLY a.xmldoc.nodes('./R') AS b(t) --Join to table containing proposed changes based on value to change LEFT JOIN ( SELECT Child.value('./old', 'varchar(100)') old , Child.value('./new', 'varchar(100)') new FROM @my XML.nodes('/qa Updates/qa Update') AS N(Child ) ) q2 ON '(' old ')' = t.value('.', 'varchar(200)') ) Modified WHERE Modified.constraint_id = base.constraint_id FOR XML path('')) ,1,1,'') New_Val FROM @tmp Constraint Base ) c SELECT * FROM @tmp Constraint Then use that in my from statement to update the data in the orignal table.
Generally, because a document database is schema-agnostic, the fastest path to productivity is ingesting data "as is" and then modeling based on desired outputs.
Many legacy systems have been created by using relational database operating not for the Internet expression.
Since the relational database is not an efficient way for data explosion, electronic transfer of data, and electronic business on the Web, we introduce a methodology in which a relational schema will be translated to an Extensible Markup Language (XML) schema definition for creating an XML database that is a simple and efficient format on the Web.
