The Teradata Debugger for C/C++ UDF (CUDB) Eclipse Plug-in provides a Graphical User Interface for CUDB on the Eclipse IDE. Refer to the Installation Guide for instructions on installing CUDB Eclipse via the Eclipse Update Site process. You can either download the zip file, or use the Debugger URL (specified in the Installation Guide) in the install process. To ask questions or discuss issues with CUDB Eclipse, please use the Teradata Debugger Forum. Not recommended for use on production systems. Debugging directly on a production system could potentially affect the overall system performance and cause other issues. Teradata does not support issues caused by use on a production system.

The XML Data type, introduced in Teradata 14.10, provides the following new capabilities: •A new XML data type that allows you to store XML content in a compact binary form that preserves the information set of the XML document, including the hierarchy information and type information derived from XML validation •Functions and methods on the XML type that support common XML operations like parsing, validation, transformation (XSLT) and Query (XPath and XQuery) •Supports the XQuery query language for querying and transforming XML content •Supports the following SQL/XML functions and stored procedures:     •XMLDOCUMENT •XMLELEMENT •XMLFOREST •XMLCONCAT •XMLCOMMENT •XMLPI •XMLTEXT •XMLAGG •XMLPARSE •XMLVALIDATE •XMLQUERY •XMLSERIALIZE •XMLTABLE •AS_SHRED_BATCH •XMLPUBLISH •XMLPUBLISH_STREAM Benefits •Removes the requirement to map between hierarchical and relational models prior to storing the XML contents. Previously, this was required when using the XML shredding and publishing functionality in Teradata XML Services. •Provides the ability to preserve document identity. In contrast, the shredding facility that Teradata XML Services supports only extracts the values out of the XML document without retaining the document identity. •Provides a compact method for storing XML content where the internal representation is 5~10 times smaller than the original text representation. •Provides standard query language support for querying XML using XQuery 1.0 and XPath 2.0. •Provides a more efficient method for parsing, transforming and querying XML content. •Integrates the functionality in the Teradata XML Services offering into Teradata Database using syntax that conforms to the ANSI SQL/XML specification.   Considerations •The XML type accommodates values up to 2GB in size. However, operations like XSLT and XQuery, which load documents into memory, are only supported on documents that are smaller in size, where the processing operation does not require more memory than specified by the XML_MemoryLimit DBS Control field. This field caps the amount of memory available for XML operations so that these operations do not strain memory resources. A pseudo-streaming version of XQuery is allowed on large documents via the XMLEXTRACT method on the XML type. •XML path indexes are not supported. •XML schemas and XSLT stylesheets are not managed by Teradata Database.   Schema and Stylesheet Consolidation Utility The Schema and Stylesheet consolidation utility  is available for download as a zip file on this page. There is one significant change in this utility compared to the user documentation. The user documentation speaks of two executables ConsolidateSchema.exe and ConsolidateStylesheet.exe. In this version of the utility the two have been combined into a single executable csldgen.exe. The Readme.txt file included in the zip file gives more details regarding the need for schema and stylesheet consolidation and how to perform such consolidation. This utility is only relevant if your schemas and stylesheets use imports and includes.

Teradata XML Services provide assistance in database transformation of XML structures to and from relational structures. This is primarily an enterprise fit feature. XML in this context is regarded as a data format that is used to describe incoming or outgoing warehouse data. A key concept for this feature is that we are not transforming to store XML but rather to maintain a relational data model or to integrate relational data into an enterprise XML message structure! The relational data model is bested suited for enterprise analytics. XML structures are best suited for enterprise integration. Teradata XML Services is supported on Database Versions 13, 13.10 and 14. As of Teradata Database version 14.10, much of the XML Services functionality has been implemented as part of the XML data type in the database, and Teradata XML Services as a separate download will not be supported for 14.10 and future versions. Mappings created for XML shredding and publishing can be used for 14.10 as well (except for XSLT shredding),  but the names of the stored procedures will change. Please see the Teradata XML book in the database user documentation for further details. This feature will be delivered asynchronously from any specific Teradata warehouse release. The delivery format will be as a web download, available for each Teradata server platform. The feature is considered a part of the Teradata product and will be supported through normal support channels. Teradata XML Services consists of the following components: Xerces XML parser and Xalan XSLT transformer packaged as a platform specific operating system library. Shredding Framework which consists of a combination of stored procedures and functions. A stored procedure controls the shredding process. When shredding one to a few documents the stored procedure directly invokes the data maintenance DML. When shredding many documents, the stored procedure uses a set-based approach through the invocation of a table generation function. Parallel Publishing Framework which consists of a combination of stored procedures and functions. A stored procedure will control the publishing process. The stored procedure can either return a string representing an XML object type or a SQL statement that represents the XML data stream. The SQL statement can be reused in views, macros, fast export, etc. General purpose XSLT transformation function. Two XPATH search functions, one that returns a scalar character value and one that returns an XML fragment character value. XML schema validation function. XML Schema and Stylesheet loading and dependency resolution. XML schema generation procedures. Perl based installation process. For community-based support and to share your implementation ideas and concerns, please visit the Extensibility forum.
