XML representation of a relational database. A relational database consists of a set of tables, where each table is a set of records. A record in turn is a set of fields and each field is a pair field-name/field-value. All records in a particular table have the same number of fields with the same field-names. This article describes an application of (a simple subset of) XML that can be used to represent such a database. The relational data-model also defines certain constraints on the tables and defines operations on them. We are not concerned with the constraints and operations here. In other words, we are not trying to create a query language or a data-definition language, just a language that captures the data in a database or in a particular view of the database. Several such languages are possible, of course, and it not hard to come up with alternative and equally valid ones as the one described below.

Copyright 1999-2005 by Ronald Bourret Last updated September, 2005 This article also available in: Table of Contents 1.0 Introduction This paper gives a high-level overview of how to use XML with databases.

It describes how the differences between data-centric and document-centric documents affect their usage with databases, how XML is commonly used with relational databases, and what native XML databases are and when to use them. NOTE: Although the information discussed in this paper is (mostly) up-to-date, the idea that the world of XML and databases can be seen through the data-centric/document-centric divide is somewhat dated. 2.0 Is XML a Database? Before we start talking about XML and databases, we need to answer a question that occurs to many people: "Is XML a database?

" An XML document is a database only in the strictest sense of the term. 3.0 Why Use a Database? For example, suppose you have an e-commerce application that uses XML as a data transport. 4.0 Data versus Documents.
