Xquery in IBM DB2 10 for Z/OS
® XQuery in IBM DB2 10 for z/OS Introduction In November 2011, support was added for XQuery in IBM® DB2® 10 for z/OS® through APARs PM47617 and PM47618. XQuery extends XPath with new language constructs, adding expressiveness to the IBM pureXML® features of DB2. Many XQuery queries can be rewritten using a combination of XPath and SQL/XML, but often XQuery is the preferred tool, as it is an easier to code and more readable alternative. Like XPath, XQuery is a W3C standard, and its addition is a further step in ensuring compatibility within the DB2 family of products. XQuery has been available in DB2 for Linux, UNIX, and Windows since 2006. Constructs of XQuery XQuery introduces new types of expressions that can be used in XMLQUERY, XMLTABLE, and XMLEXISTS function calls. The XMLQUERY function is used in the SELECT clause of an SQL query to specify which XML data to retrieve. The XMLTABLE function is used in the FROM clause to extract XML data in a table format. The XMLEXISTS function is used in the WHERE clause to specify under which conditions to retrieve the data. XQuery expressions are most applicable with XMLQUERY, because arguments to XMLEXISTS can be specified by XPath expressions, which are indexable, while XQuery expressions are not. XMLQUERY is not indexable. XQuery can be used in XMLTABLE as the row expression or column expressions, but is usually not needed for the relational result. XQuery could be used to construct new XML values for the XML column results. There are three types of expressions that can be used alone or in combination: FLWOR expressions A FLWOR expression is a loop construct for manipulating XML documents in an application-like manner. -

Oracle Big Data SQL Release 4.1
ORACLE DATA SHEET Oracle Big Data SQL Release 4.1 The unprecedented explosion in data that can be made useful to enterprises – from the Internet of Things, to the social streams of global customer bases – has created a tremendous opportunity for businesses. However, with the enormous possibilities of Big Data, there can also be enormous complexity. Integrating Big Data systems to leverage these vast new data resources with existing information estates can be challenging. Valuable data may be stored in a system separate from where the majority of business-critical operations take place. Moreover, accessing this data may require significant investment in re-developing code for analysis and reporting - delaying access to data as well as reducing the ultimate value of the data to the business. Oracle Big Data SQL enables organizations to immediately analyze data across Apache Hadoop, Apache Kafka, NoSQL, object stores and Oracle Database leveraging their existing SQL skills, security policies and applications with extreme performance. From simplifying data science efforts to unlocking data lakes, Big Data SQL makes the benefits of Big Data available to the largest group of end users possible. KEY FEATURES Rich SQL Processing on All Data • Seamlessly query data across Oracle Oracle Big Data SQL is a data virtualization innovation from Oracle. It is a new Database, Hadoop, object stores, architecture and solution for SQL and other data APIs (such as REST and Node.js) on Kafka and NoSQL sources disparate data sets, seamlessly integrating data in Apache Hadoop, Apache Kafka, • Runs all Oracle SQL queries without modification – preserving application object stores and a number of NoSQL databases with data stored in Oracle Database. -

Multi-region data replication Enterprise grade software Applications send network requests against an Oracle NoSQL data store to and support perform database operations. With multi-region tables, data can be globally distributed and automatically replicated in real-time across different regions. Data can be modeled as fixed-schema tables, documents, key-value pairs, and large objects. Different data models interoperate with each other through a single programming interface. Oracle NoSQL Database is a sharded, shared-nothing system which distributes data uniformly across multiple shards in a NoSQL database cluster, based on the hashed value of the primary keys. An Oracle NoSQL Database data store is a collection of storage nodes, each of which hosts one or more replication nodes. Data is automatically populated across these replication nodes by internal replication mechanisms to ensure high availability and rapid failover in the event of a storage node failure. -
