Collaboration becomes a reality when everyone speaks the same language and can easily learn how to use the same tools as their colleagues Java is a great example since it’s a quite popular programming language Today’s Java frameworks are sufficiently abstracted away from the database so then when the DBA is talking to the developer they aren’t really speaking the same language The DBA looks at the development code and it’s not obvious what the sequence of instructions would do to the database This allows IT staff to move from one position to another, giving CIOs the benefit for a more fluid workforce Some studies estimate that 70% of IT budgets are focused on people costs, compared to 30% going to hardware and software There’s a tremendous amount of labor capital involved with all the piece parts from an array of different vendors 7 Toolset Q&A • I need to create a logical data model You need to use Rational Data Architect • I need to build and debug a SQL stored procedure You need to use Developer Workbench • I need to create a table for DB2 for LUW You need to use Control Center • I need to execute some commands on DB2 for z/OS You need to use Command Editor • I need to catalog my DB2 data servers You need to use Configuration Assistant • I need to change a few configuration parameters You need to use Control Center • I need to check the health of my DB2 for LUW data server You need to use Health Center or Performance Expert • I need to administer my DB2 for LUW Replication configurations You need to use Replication Center 8 Today’s Business Has Collections of Disparate Single-Purpose Products IBM Rational Data Architect Embarcadero ER/Studio Quest Spotlight Oracle Tuning Pack Design Sybase PowerDesigner CA ERwin IBM Optim Data Growth Optimize Solution IBM Data Studio Developer Guardium Quest Solix EDMS InTrust Oracle JDeveloper IBM Optim Govern Develop Quest TOAD Embarcadero Quest Central Operate IBM Comparison Rapid SQL Oracle Tool for DB2 z/OS Vault Data Studio Oracle Diagnostic Deploy Administrator Pack BMC Patrol Embarcadero Change Manager IBM DB2 tools Oracle Change Management Pack 9 Integrated Data Management Core Values • Providing end-to-end data lifecycle management • Solutions across the lifecycle • Heterogeneous • Facilitating cross-organizational collaboration for business alignment • Integration and synergy across functional components • Flexibility to provide the ease of use small businesses require with the scalability to manage the large enterprises • Download and go type model • Ability to manage hundreds of servers 10 Data Studio Packaging 11 DB2 Developer Workbench vs. Data Studio Developer Workbench Data Studio SQL Query Editor Integrated Query Editor – SQL + XQuery SQLJ Editor SQLJ Editor SQL Builder SQL Builder XQuery Builder XQuery Builder SQL Routine Debugger SQL Routine Debugger Java Routine Debugger Java Routine Debugger XML Editor XML Editor XML Schema Editor XML Schema Editor Data Management Data Management Visual Explain Visual Explain Project Management Project Management ER Diagramming Data Studio is a full replacement of Data Distribution Viewer DB2 Developer Workbench Object Management Privilege Management plus much more Browse & Update Statistics Security Access Control • DB2 for Linux, Unix, Windows v8.x, v9.1.x, v9.5 Connection Management integration with Kerberos and LDAP • DB2 for z/OS v7, v8, v9 Data Web Services • DB2 for i5/OS v5r2, v5r3, v5r4 IDS Server Support • Informix Dynamic Server (IDS) v9.x, v10.x, v11 Health Monitoring DB2 for LUW 9.5 and DB2 z/OS v9 Instance and database commands Utility support Data Studio v2.1 Data management support View and force applications 12 Why IBM Data Studio?

  • 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.

The goal of the paper is not to NoSQL systems. These systems have different design points do an exhaustive survey of NoSQL systems. The aim is to do a compared to the relational DBMSs (RDBMSs), like DB2 and broad brush analysis of what these developments mean - the good Oracle, which have now existed for about 3 decades with SQL as and the bad aspects! Based on my more than three decades of their query language. The NoSQL wave was initially triggered not database systems work in the research and product arenas, I will by the traditional software product companies but by the non- outline what are many of the pitfalls to avoid since there is traditional, namely the Web 2.0, companies like Amazon, currently a mad rush to develop and adopt a plethora of NoSQL Facebook, Google and Yahoo.

  • Multi-Model Databases: a New Journey to Handle the Variety of Data
    0 Multi-model Databases: A New Journey to Handle the Variety of Data JIAHENG LU, Department of Computer Science, University of Helsinki IRENA HOLUBOVA´ , Department of Software Engineering, Charles University, Prague The variety of data is one of the most challenging issues for the research and practice in data management systems. The data are naturally organized in different formats and models, including structured data, semi- structured data and unstructured data. In this survey, we introduce the area of multi-model DBMSs which build a single database platform to manage multi-model data. Even though multi-model databases are a newly emerging area, in recent years we have witnessed many database systems to embrace this category. We provide a general classification and multi-dimensional comparisons for the most popular multi-model databases. This comprehensive introduction on existing approaches and open problems, from the technique and application perspective, make this survey useful for motivating new multi-model database approaches, as well as serving as a technical reference for developing multi-model database applications. CCS Concepts: Information systems ! Database design and models; Data model extensions; Semi- structured data;r Database query processing; Query languages for non-relational engines; Extraction, trans- formation and loading; Object-relational mapping facilities; Additional Key Words and Phrases: Big Data management, multi-model databases, NoSQL database man- agement systems.

  • Xquery Rewrite Optimization in IBM DB2 Purexml
    XQuery Rewrite Optimization in IBM R DB2 R ∗pureXMLTM Fatma Ozcan¨ Normen Seemann Ling Wang IBM Almaden Research Center IBM Silicon Valley Lab IBM Silicon Valley Lab 650 Harry Road, San Jose 555 Bailey Road, San Jose 555 Bailey Road, San Jose Abstract In this paper, we describe XQuery compilation and rewrite optimization in DB2 pureXML, a hybrid relational and XML database management system. DB2 pureXML has been designed to scale to large collections of XML data. In such a system, effective filtering of XML documents and efficient execution of XML navigation are vital for high throughput. Hence the focus of rewrite optimization is to consoli- date navigation constructs as much as possible and to pushdown comparison predicates and navigation constructs into data access to enable index usage. In this paper, we describe the new rewrite transfor- mations we have implemented specifically for XQuery and its navigational constructs. We also briefly discuss how some of the existing rewrite transformations developed for the SQL engine are extended and adapted for XQuery. 1 Introduction XML has emerged in the industry as the predominant mechanism for representing and exchanging structured and semi-structured information across the Internet, between applications, and within an intranet. Key benefits of XML are its vendor and platform independence and its high flexibility. With the proliferation of XML data, several XML management systems [7, 10, 17, 5, 4, 6, 12, 11, 14] have been developed over the last couple of years. All major database vendors have released XML extensions to their relational engines, in addition to many native XML management systems.

  • Starting Tips for Using Purexml in DB2 on Z/OS
    With DB2 9 it became possible to store, retrieve and query XML documents in DB2 for z/OS ,using the pureXML functionality. Although today most DB2 DBA are familiar with the concepts of this new hybrid technology, it requires some effort to obtain the skills to be able to implement this new technology on site. This presentation will focus on a practical case the speaker used to help acquire these skills, by showing some experiences and scenario's that every one can try out and play with in their own environments. The objectives of this presentation are : •Understand the benefits of storing XML data in pureXML format instead of relational format •How to create and populate an XML database with real data and realistic volumes to play around •How to use SQL and XPath to query this XML data ; how to handle namespaces •How to implement XML schemas •Understand the use of XML indexes to improve query performance 1 2 3 4 5 6 XML, the extensible markup language acts as a flexible and self-describing data format for data exchange, web services, and service-oriented architectures. XML is also a hierarchical data model that is inherently different from the relational model. While relational data processing is based on rigorous and predefined schemas that allow for limited flexibility, XML is well-suited to represent data with variable or evolving schemas. XML is also commonly used as a data-format for semi-structured and unstructured data . Depending on the performance and flexibility requirements of particular applications, you will find that in some cases XML is a better choice than a relational schema, and in other cases relational data has advantages over XML.
