XML labelling schemes refer to tools which are basically used to assign unique codes to the nodes in the tree such that the constant time is taken in the determination of the relationship between two nodes from the codes. The basic binary encoding and the enhanced binary encoding can be used for labelling the XML tree. A label consists of labelling schemes which can be compared with the structural join performance of other labelling schemes (Min, Lee, & Chung 2009: 505). A good labelling scheme is, therefore, determined by how well it determines the relationship between XML elements and how it quickly it offers access to the desired data. Counting odd division values of a label is used to determine the level of the optimized prefix compression scheme; where the prefix-based labelling scheme lends itself of a name directory with (potentially) all element names occurring in the XML document (Haustein & Härder 2007: 515).Labelling schemes in existence can be categorised as either interval labelling or prefix labelling(Sexton 2009:160).
For interval labelling scheme, a pair of numbers are assigned to label each node in the tree, with the first number being the pre-order number and the second one the post-order number (Wu, Lee & Hsu 2004:68).This labelling scheme supports XML query processing of the XML efficiently but has the shortcoming of processing the dynamic updates of the tree structure (Bouganim, Ngoc, & Pucheral 2004: 87). Therefore, insertion or deletion of new nodes requires relabeling of the existing nodes (Ma & LI 2010: 107).
In prefix labelling on the other hand, a path from the root is used to label each element and therefore the label of the parent node is the prefix for all the descendants (Kaplan, Milo, & Shabo 2002: 958). Society for Industrial and Applied Mathematics).This labelling scheme is advantageous in that it is dynamic and therefore ...Download file to see next pagesRead More

Reflection and Evaluation of Technologies Such As XML and Flash

...?XML There are those who believe that Extensible Markup Language or more commonly known as XML is the most exciting technology today as it supposedlyinteracts with most organizations globally, with the omnipotence of the Internet technology. This could be true because XML is a computing language that is designed for the simple and fast use and access of information on the Internet, an important objective that could spell tremendous productivity, and, for enterprises, potentials for profitability. It is mainly a platform for documents and textual data using the Unicode standard, which effectively encodes, represent and manage majority of the languages of the world. One will find that XML documents are primarily constituted by texts... to...

...3D XML Overview X3D Overview X3D is a scalable open software standard for creating and presenting interactive 3D content in real-time. Merging real-time 3D data, presentations and controls with non-3D content becomes fast and easy using X3D’s XML-encoding and Scene Authoring Interface (SAI) features, which are provided for both web and non-web applications. X3D visual effects and behavioural modelling have a great number of uses, including GIS, CAD, visual stimulation, medical visualization, entertainment, education and other such multimedia presentations. The software can also be used across hardware devices. X3D builds on the success of the Virtual Reality Modelling Language (VRML) with...

Efficient Xml (extensible Markup Language) and AJAX

...Running head: Efficient Xml (extensible Markup Language) and AJAX XML Affiliation September 2009 Task XML XML (eXtensible Markup Language) is a increasingly more fashionable arrangement for sharing data that permits web page developers to build customized tags, as well as make use of predefined tags. In XML, developers can make a link which points to several Web sites in place of a single site. With XML, a server transmits a full record to the client, facilitating the client to carry out major part of the processing devoid of going back to the server (Shelly, Cashman, & Vermaat, 2005, p. 682). XML facilitates the development of customized tags. These tags can be used all the way through the organizations, allowing the description... ,...

XML as a programming tool

...) Briefly explain DTDs vs. XML Schemas. DTDs (Data Type Definitions): DTDs describe the type of document the user is dealing with. Their primary purpose is to authenticate and verify the integrity of the document through validation – the process of comparing an XML document to its DTD. (Schaffner, 2002). Pros: DTDs provide validating parsers with a map to validate the XML document (Schaffner, 2002). DTDs are the standard protocol for describing XML documents and therefore, they are supported by almost every XML package (Schaffner, 2002). Cons: DTDs lack good type-checking (Schaffner, 2002). DTDs have a limited capability in describing the...

Static vs. Dynamic XML queries or from databases providing an interaction that is much needed. A static XML query is concerned with the retrieval of information and updating the node contents. It does not involve any other changes to the structure of the document (OLTEANU 2004). A dynamic XML query not only retrieves information and updates the content of the document in question; it also inserts new nodes while at the same time deleting the existing nodes often resulting in a change in the document structure. There has been a surge in the need for XML updates thanks to the growing preference for XML as a data exchange format. A labeling scheme...
