xml vs relational data?
465106
XML (Extensible Markup Language) is a W3C initiative that allows information and services to be encoded with meaningful structure and semantics that computers and humans can understand. XML is great for information exchange, and can easily be extended to include user-specified and industry-specified tags.\n\n\n\nRelational data is useful for organizeing data in table format.  A database system in which the database is organized and accessed according to the relationships between data items without the need for any consideration of physical orientation and relationship. Relationships between data items are expressed by means of tables

XML (Extensible Markup Language) is a subset of SGML (Standard Generalized Markup language.)  XML helps data be served, received, and processed on the web because XML describes data in a very specific, ordered, and hierarchical way.  XML is described and maintained by the W3C (the same organization that defines HTML) and is now in version 1.1.  You can read more about XML at \nhttp://www.w3.org/TR/xml11/\n\nHere's an example of a snippet of xml\n\n<library>\n  <book>\n  <title>Green Eggs and Ham</title>\n  <author>Dr. Seuss</author>\n  <pages>28</pages>\n  </book>\n  <book>\n  <title>Dune</title>\n  <author>Frank Herbert</author>\n  <pages>779</pages>\n  </book>\n</library>\n\n\nFor more info on RSS, I'd read "What is RSS" from Xml.com authored by Mark Pilgrim ( http://www.xml.com/pub/a/2002/12/18/dive-into-xml.html )

For what you are doing, there is no practical difference.\n\nThere are differences in terms of complex database activities, such as using triggers; changing server variables on the database server; error handling; the nature of the way data is returned, and other very complex, vary narrow semantics.

This website defines primary and secondary data:\nhttp://members.tripod.com/~mccurtain_2/genietips/tip15.html\nI hope this helps.

Dude; your talking about information organised into catergories and within a central mainframe ---> this basically means you need to create a content management system or download a free one for your webserver ( i assume you have a server) i recommend nucleuscms.org however if you want another search 'content management system' in google and you can download and install loads of free ones into your server to use them to organise data effectively to achieve you goal this can be done following their tutorials in less that 6hours to have a working car-sales website

Excel is a spread sheet and can be used to show relations of between data. Usually what you but in to excel is raw data and excel acts as a sophisticated calculate. Excel can analyze data, and display graphs to show patterns.\n\nAccess is a database. It is place to store a lot of data - for the record. Calculations are not made in access. But you can make a lot of fun intersections between data.

The structure is how the database will be organised and the content is the actual data.

Simple answer is no.\nXML is used to store data in structured fashion. While you can store your game data in XML format, and indeed it is recomended way unless you don't want to make your game data public, you have to use other language to write algorithms.

each node is homogeneous with a reference to the next node. instead of storind data in contiguous locations, we can have linked lists to store the same data, by utilizing the free space wherevr it's available in memory. u can have singly, doubly linked lists and circular linked lists. stakcs and queues can also be omplemented thru them.

get the ORielly book XML & Java. Its really amazing and in depth. Lots of places you can download the EBook as well

It helps you with the classification of items. I assume you are referring to a taxonomy you might find with some XML files. Sorry if I am mistaken, but I will assume that is what you are referring to.\n\nA great example of a taxonomy file would be one that refers to our planet for instance. At the top is the "World" which may have seven continents. Each continent would have all the countries on that continent. Each country would have its capital city. You get the idea.\n\nWith this in mind, here are some advantages:\n\n1) It could be used for verification purposes, to make sure you have all the data needed. For instance, your taxonomy said there should be an Australia component, but no Australia data was found.\n\n2) Quick lookup. Since a taxonomy lists everything and categorizes it into a hierarchical fashion, you can quickly jump to World/Europe/Italy to find Italy's capital.\n\n3) Presents a high overview of large amounts of data. Shows you how complex data items like a "country" fits into the world. \n\n4) It is a simple catalogue of all items. You could loop through a taxonomy XML file and list the entire contents of all the countries/capitals in the world using just one file.\n\n5) Lastly, can help identify what an item is quickly. I see the Belgium is apparently a country in Europe which is part of the World.\n\nThese are some of the advantages that a taxonomy can offer you. I like to think of taxonomies more like an index of a book that tells you on which page you can find the subject you are looking for.\n\nAgain I am sorry if an XML taxonomy is not quite what you were asking for. Hope it helps!

No. It is fairly easy to do if you are familiar with database design; your biggest challenges will be in how you store and order your information, not in how it will be displayed.

No, the structure actually is defined in the .dtd file.\nYour .xml file contains only the data. If the data u give in .xml doesn't match ut .dtd, the database wont be a valid one. So, if u want to know all important columns of the database, see the .dtd file. That gives u the exact structure.

XML was designed to describe data and to focus on what data is.\nHTML was designed to display data and to focus on how data looks.\n\nThis is the Simple difference ...

The XML Document Object Model (XML DOM) defines a standard way for accessing and manipulating XML documents.\n\nThe DOM presents an XML document as a tree structure, and gives access to the structure through a set of objects.
