Oracle xmltype store as binary trading
Documents might or might not conform to an XML schema. If the XML data contains islands of structured, predictable data, and your queries are oracle xmltype store as binary trading, then use XMLIndex with a structured component to index the structured islands even if the data surrounding these islands is unstructured. This storage model also provides efficient partial updating and streamable query evaluation. The data is relatively structured, but your applications do not take advantage of that structure: Instead, you typically insert and select whole XML documents at a time.
Only documents that conform to the XML schema can be stored. Partial updates and selections are common. Object-relational storage of XMLType data is generally appropriate for this use case.
You cannot remove such constructs. Queries oracle xmltype store as binary trading cannot use an index use streaming XPath evaluation, which can also be fast. You do not have an XML schema for your data. ETL use cases often integrate data from multiple applications that are maintained or hosted by multiple parties using different software and hardware systems.
A use case where you might use both components would be to support queries that extract an XML fragment from a document whenever some structured data is present. Use structured-component XMLIndex indexing when query paths are known, and use path-subsetted unstructured-component XMLIndex indexing when paths are not known beforehand ad hoc queries. Use Oracle xmltype store as binary tradingwith a structured component for each of the structured islands. You can tailor performance and functionality to best fit the kind of XML data you have and the ways you use it. Object-relational storage of XMLType data is generally appropriate for this use case.
You need the property of document fidelity, preserving all original whitespace. You can create B-tree indexes on the underlying object-relational columns. Retrieval approaches can also be different for different kinds of data.
Because it is an oracle xmltype store as binary trading data type, your applications and database queries gain in flexibility: Important design choices for your application include what XMLType storage model to use and which indexing approaches to use. Likewise, XML developers can leverage the power of XML standards while working in the context of a relational database. The structured component of the index would be used for a query WHERE clause condition that checks for the structured data.
There might not be an associated XML schema, or the XML schema might allow for high data variability or evolve considerably or in unexpected ways. You can create B-tree indexes on the underlying object-relational columns. You do not have an XML schema for your data.
