XML: Efficient Structuring and Transmission of Data

XML: Extensible Markup Language describes how to structure information for facilitating its efficient transmission from processed output to physical or virtualized device or program to program. The XML standard has emerged as an important component in information technology for organizational enterprise; it is open source software.

Extended Markup Language - Base Platforms

  Web Development   XML and Documentation   Database Development  
  Simple Object Access Protocol   Office Open XML   Store Data in XML Format  
  Web Services Description Language   Source Code Documentation   XML-enabled Database  
  Document Type Definitions   Rendering XML   Native XML Database  
  XML Schema       XML for Data Transport  

XML provides a foundation for organizing and presenting data: the details can either be provided or developed. For programmers, XML simplifies and obviates the need for developing code for data conversion into a format for a development platform. The structure of the data can be isolated from the program logic; this is important when the data exchange is complex and not a simple string. Effort and resources can then be more efficiently utilized in designing and coding the application for processing and presenting the data.

XML's capabilities for structuring data are essential for utilization with enterprise database applications and display on web browsers. Parsing XML documents, converting XML to and from different formats, and translating objects for use with databases are required to leverage XML for multi-platform processing and creating links to multiple documents. XML, in conjunction with servlet and Java Server Pages APIs, is important for building an effective e-commerce web site. XML also is used with scripting languages including Perl, Python, PHP, Ruby on Rails, Rebol, and AppleScript.

Industry-specific schemas can be used for storing and transmitting information. XML provides DTD: document type definitions for writing specifications on categorizations of data. Also known as schemas, DTDs are extensible and provide a baseline commonality for creating code which communicates with multiple applications in the same industry or field. As XML continues to gain acceptance, it will enable data to be stored and structured more consistently and transferred easier. There are tools, utilities, and libraries of code available for utilization with XML.

XML has reached a mature stage where it is widely deployed and there are very few reported problems. A range of supporting standards emerged that help process, structure, transform, query, and format XML data: XML Schema, XLST, XSL-FO, XPath,XQuery, and XBRL. They enable standard-based information processing that spans operating systems, platforms, and software products. XMLis a widely used global format for representing and exchanging information. XML can work with JSPM, linked data, documents, large databases, and the IoT: Internet of Things.

Trends in XML Utilization

XML and Databases

An XML database is data persistence software system which allows data to be stored in XML format. This data can then be queried, exported, and serialized into the required format.

There are two major classes of XML databases extensively used with web server platforms. XML-enabled databases map all the XML to a traditional database, accepting XML as input and rendering XML as output. The database does the conversion itself as opposed to relying on middleware.  Native XML in which the internal model of the databases is dependent on XML and uses XML documents as the unit of storage.  However, these documents can not be stored in the form of text files.

Composite Development with IBM Rational Developer for System z

Rational Developer for System z is a development platform for delivering information technology services which reduce application complexity, deploy new applications, and modernize existing assets. It can be used to interactively test and deploy cross-platform web technologies, mainframe applications, and low-level programming languages. It provides the capability to create and utilize web services and XML for viewing, editing, and validating WSDL, DTD: document-type definitions, and XML schemas and transforming XML documents into text, HTML, or other XML document types.

COBOL or PL/1 adapters can be generated and CICS TS V3 WSBind is used for converting between Web Service Description Language, XML and CICS program data in a web services environment.

XML and .NET

Microsoft .NET has been designed to take advantage of XML with enhancements to improve performance and utilization. The .NET Framework XML classes were built on the DOM Level 2 Core, XPath 1.0, XSLT 1.0, XSD:XML Schemas and SOAP: Simple Object Access Protocol; it is an improved programming model. In addition to the DOM foundation, the .NET Framework XML classes include a stream-based API that offers a pull model interface.

XML Web Services and Web Apps

XML web services are a component in the movement to the distributed computing model. Open standards and the requirement for communication and collaboration among people and applications have created an environment where XML web services serve as the platform for application integration: Internet programs and web apps. Applications are constructed using multiple XML web services from sources that work together regardless as to where they reside or how implemented.

The features common to the XML web services include:

  • exposing functionality to web users through a standard web protocol; this will be SOAP in most situations.
  • providing a methodology for describing interfaces in sufficient detail which allows a client application to be built with a bi-directional communication and processing featureset. WSDL: Web Services Description Language provides that document in XML.
  • registering XML web services so that potential users can find them. This is done with UDDI: Universal Discovery Description.

XML Training by SYS-ED

SYS-ED system consultant instructors have been in the forefront of both XML consulting and training on web platforms - HTML, DHTML, scripting languages, open standards, and vendor APIís. SYS-EDís XML training addresses the operational requirements of Fortune 1000 companies, government municipalities, and healthcare providers at these levels.

  • Background and fundamentals required for the creation of elements, attributes, and entities.
  • How to apply the principles of design and data using DTDs and schemas.
  • XML scripting and processing.
  • E-commerce with XML and JSP.

SYS-EDís consultancy derived XML course offerings and XML training programs reflect 25+ years of evolutionary experience with internetworking, web servers, databases, programming languages, and mainframe system software. The examples and exercises provide the knowledge and skillset to utilize XML and build scalable web-based applications. At the client discretion, our staff will develop custom-built alternatives to XML schemas. Few software or consulting companies have been teaching XML longer or better.

Qualifying a Training Assignment

SYS-ED will not accept an XML training assignment without a consultation with the prospective client organization. We review the background of the employees to be trained, operating environment, documented standards, and project specifications to select the code snippets, examples, skeleton programs, and machine exercises. We then prepare a training strategy: lesson plan, modular courseware, training aids, and validation assessment. This allows us to identify and differentiate between teaching an industry standard course as compared to the clientís true need for specialized training: structured methodologies and code reengineering. This foundation is used for training client organizations to migrate an existing investment in mainframe and client/server infrastructure to Internet and mobile devices applications. Upon completion of an instructor-led XML course at the client location, it is standard policy to organize content for future utilization in a web-based training infrastructure.

Courseware for Teaching 1

SYS-ED's courseware library consists of student handouts, training aids, documented walkthroughs, and industry-specific exercises. The Computer Education Techniques knowledge base is a service for answering questions, inclusive of the research and validation of the accuracy of information in the public domain. Content selectively is added to SYS-ED course handouts and training aids. The long term strategy is to have our courseware recognized as a NRV: Nationally Recognized Vendor.

Industry Standard XML Courses

Information technology infrastructure is becoming increasingly hybrid with a combination of commercial and open source software: web browser, operating system, web server, database, and middleware. SYS-EDís XML courses have been developed based upon the foundation of classic adult learning theory and the application of the standards of the New York State Department of Education.

We explain and teach:

  • The protocols serving as the foundation of web services and its utilization with XML.
  • Migrating and upgrading applications from the client server to the emerging service oriented architecture standard.
  • Logical and physical design and performance optimization of the source database engine.
  • Design of the interface and presentation format.
  • Guidance on web development utilizing .NET and open source Java frameworks.
  • Demonstration of interoperability of .NET and Java and identification of pitfalls in relation to the vendor documentation.

And when not confident that we can provide a superior training outcome, will politely turn down an assignment.

SYS-ED has been conducting courses in the public domain since 1980; however, there have been changes in the laws and regulations governing computer training in the state of New York. The schedule on our websites reflects a projected time frame for licensure with the New York State Department of Education - Bureau of Proprietary School Supervision and submission and approval of curriculum.


XML and JSON both have been designed to provide a way for describing hierarchical data structures and facilitating data transportability and consumption in a standardized way. XML is used to serialize data for transmission to and from applications. The sender must encode the data to be serialized based on a document type definition recognized by the recipient. Independent of the DTD; this generates padding around the actual data. The size of XML documents will be large in comparison with the actual set of contained values. The application or client agent must receive the stream of XML and decode the data for placement into memory.

There are two broad categories of XML databases: 1- Native XML database and 2- XML support to augment a conventional relational database.

A native XML database:

  • defines a logical model for an XML document.
  • stores and retrieves documents based on the XML document model.
  • has an XML document as its base logical unit of storage.
  • is not required to have any particular underlying physical storage model.

The native support databases are: BaseX, eXist, and Sedna. SAP Sybase provides native XML support. The leading commercial databases provide their own implementation of XML software: IBM DB2 and pureXML, Oracle database with XML DB, and Microsoft SQL Server with xQuery.

JSON versus XML

JSON: JavaScript Object Notation is a structure for storing information and providing human-readable collection of data. It has been designed to bi-directionally serialize data sent to and from JavaScript applications. Despite its relationship to JavaScript, it is language-independent, with parsers available for many languages. JSON utilizes a text format which is language independent, but with conventions similar to the C-family of languages, C#, Java, JavaScript, Perl, and Python. JSON an ideal data-interchange language.


JSON Featureset

  Simplicity   Extensibility   Interoperability   Openness  
  JSON is simpler.   JSON is not extensible.   JSON is comparable to XML.   JSON is at least as open as XML.

In relation to XML, JSON implements a more compact data serialization. JSON incorporates the structure of standardized datatypes and the encoding mechanism economizes on the characters required to express the structure and value of the data. Serialized processing by an application is required to evaluate and process the text of the string using either JavaScript's built-in eval function or a compatible function in another language.
