Fun Factor: Coding with Xquery a Conversation with Jason Hunter by Ivan Pedruzzi, Senior Product Architect for Stylus Studio
Fun Factor: Coding With XQuery A Conversation with Jason Hunter by Ivan Pedruzzi, Senior Product Architect for Stylus Studio Jason Hunter is the author of Java Servlet Programming and co-author of Java Enterprise Best Practices (both O'Reilly Media), an original contributor to Apache Tomcat, and a member of the expert groups responsible for Servlet, JSP, JAXP, and XQJ (XQuery API for Java) development. Jason is an Apache Member, and as Apache's representative to the Java Community Process Executive Committee he established a landmark agreement for open source Java. He co-created the open source JDOM library to enable optimized Java and XML integration. More recently, Jason's work has focused on XQuery technologies. In addition to helping on XQJ, he co-created BumbleBee, an XQuery test harness, and started XQuery.com, a popular XQuery development portal. Jason presently works as a Senior Engineer with Mark Logic, maker of Content Interaction Server, an XQuery-enabled database for content. Jason is interviewed by Ivan Pedruzzi, Senior Product Architect for Stylus Studio. Stylus Studio is the leading XML IDE for XML data integration, featuring advanced support for XQuery development, including XQuery editing, mapping, debugging and performance profiling. Ivan Pedruzzi: Hi, Jason. Thanks for taking the time to XQuery behind a J2EE server (I have a JSP tag library talk with The Stylus Scoop today. Most of our readers for this) but I’ve found it easier to simply put XQuery are familiar with your past work on Java Servlets; but directly on the web. What you do is put .xqy files on the could you tell us what was behind your more recent server that are XQuery scripts to produce XHTML interest and work in XQuery technologies? pages. -

With each new generation of computing architecture – from centralized mainframe, to client server, to internet computing, to the Cloud – new generations of data management systems have been developed to address new applications, workloads and workflows. Today, the successful operation of corporations, enterprises, and other organizations relies on the management, understanding and efficient use of vast amounts of unstructured Big Data that may come from social media, web content, sensors and machine output, and documents. -
Diploma Thesis Christoph Schmid
Institute of Architecture of Application Systems University of Stuttgart Universitätsstraße 38 D-70569 Stuttgart Diploma Thesis No. 3679 Development of a Java Library and Extension of a Data Access Layer for Data Access to Non-Relational Databases Christoph Schmid Course of Study: Softwaretechnik Examiner: Prof. Dr. Frank Leymann Supervisors: Dr. Vasilios Andrikopoulos Steve Strauch Commenced: June 19, 2014 Completed: December 19, 2014 CR-Classification: C.2.4, C.4, D.2.11, H.2 Abstract In the past years, cloud computing has become a vital part of modern application develop- ment. Resources can be highly distributed and provisioned on-demand. This fits well with the less strict data model of non-relational databases that allows better scaling. Many cloud providers have hosted NoSQL databases in their portfolio. When migrating the data base layer to a NoSQL model, the business layer of the applica- tion needs to be modified. These modifications are costly, thus it is desirable to design an architecture that can adapt to changes without tight coupling to third party components. In this thesis, we extend a multi-tenant aware Enterprise Service Bus (ESB) with Data Access Layer, modify the management application and implement a registry for the NoSQL configu- rations. Then, we design an architecture that manages the database connections that adds a transparency layer between the end-user application and non-relational databases. The design is verified by implementing it for blobstores including a Java access library that manages the access from local applications to the ESB. Additionally, we evaluate component by measuring the performance in several use scenarios and compared the results to the performance of the vendor SDKs. -
Naxdb – Realizing Pipelined Xquery Processing in a Native XML Database System

XSLT in Context
XSLT in Context This chapter is designed to put XSLT in context. It's about the purpose of XSLT and the task it was designed to perform. It's about what kind of language it is, and how it came to be that way; and it's about how XSLT fits in with all the other technologies that you are likely to use in a typical web-based application. I won't be saying much in this chapter about what an XSLT stylesheet actually looks like or how it works: that will come later, in Chapters 2 and 3. I shall begin by describing the task that XSLT is designed to perform – transformation – and why there is the need to transform XML documents. I'll then present a trivial example of a transformation in order to explain what this means in practice. The chapter then moves on to discuss the relationship of XSLT to other standards in the growing XML family, to put its function into context and explain how it complements the other standards. I'll describe what kind of language XSLT is, and delve a little into the history of how it came to be like that. If you're impatient you may want to skip the history and get on with using the language, but sooner or later you will ask "why on earth did they design it like that?" and at that stage I hope you will go back and read about the process by which XSLT came into being. Finally, I'll have a few things to say about the different ways of using XSLT within the overall architecture of an application, in which there will inevitably be many other technologies and components each playing their own part. -
Xpath 2.0 in Context
P1: KTX WY030-01 WY030-Kay WY030-Kay-v3.cls July 7, 2004 15:52 XPath 2.0 in Context This chapter explains what kind of language XPath is, and some of the design thinking behind it. It explains how XPath relates to the other specifications in the growing XML family, and to describe what’s new in XPath 2.0 compared with XPath 1.0. The chapter starts with an introduction to the basic concepts behind the language, its data model and the different kinds of expression it supports. This is followed by a survey of new features, since I think it’s likely that many readers of this book will already have some familiarity with XPath 1.0. I also introduce a few software products that you can use to try out these new features. The central part of the chapter is concerned with the relationships between XPath and other languages and specifications: with XSLT, with XML itself and XML namespaces, with XPointer, with XQuery, and with XML Schema. It also takes a look at the way XPath interacts with Java and with the various document object models (DOM and its variations). The final section of the chapter tries to draw out the distinctive features of the language, the things that make XPath different. The aim is to understand what lies behind the peculiarities of the language, to get an appreciation for the reasons (sometimes good reasons and sometimes bad) why the language is the way it is. Hopefully, with this insight, you will be able to draw on the strengths of the language and learn to skirt round its weaker points. -

Building Workflow Applications with XML and Xquery
Building Workflow Applications with XML and XQuery By: Dr. Michael Kay In my previous articles, I introduced some of the mechanics of coding with XQuery and XSLT 2.0 — in a rapid progression from novice to advanced level I started with a brief ten-minute introduction to XQuery, went on from there to explore FLWOR expressions in some depth, and then exposed you to the wonderful benefits of writing schema-aware XSLT and XQuery code. In this article I'm going to stick with the assumption that you're a fast learner, and assume that you've now advanced beyond the coding level and are designing entire applications. (Actually, I don't really think of this as a hierarchy. Coders are the people who make the biggest difference to an IT system, which is why I decided five years ago after years of doing architecture and design that it was time to get back to coding. But application architecture is important too.) In this article I want to explore the role of XML in workflow applications. I'm using the term workflow in a very general kind of way, to describe applications that one can think of in terms of documents moving around a community of people who each perform particular tasks. Processing an insurance claim, or a bug report, or a capital requisition are examples that come to mind. Many processes in publishing can be viewed as workflow applications, and one also can use the idea for a spectrum of business processes from the very everyday (like processing an invoice or scheduling a meeting) to the very complex and soft (like acquiring another company). -
