The following white papers (reports) have been added to our website to explain new developments concerning XQuery. These reports include an explanation of the new development, and are here to help educate you about XQuery and its services.
Alone or in conjunction with other DataDirect solutions, such as Shadow (for mainframe access), the Data Integration Suite can help reverse rising costs via savings in multiple areas. This paper describes the Suite and its capabilities, and illustrates its value proposition with a variety of customer testimonials and use cases across diverse industries.
Learn how DataDirect XQuery is being used to help the insurance industry develop and manage applications that must adhere to ACORD (Association for Cooperative Operations Research and Development) standards for the insurance, reinsurance, and related financial services industries.
With a vast amount of data being published in XML format by multiple sources, the need has arisen for an easy and efficient means of extracting and manipulating this information. XQuery has emerged as an ideal way to aggregate data from Web services, relational databases, and other applications that employ XML.
You might think XQuery does everything and is well understood, but misconceptions and misunderstandings still exist in the software development community about XQuery. In this article, Frank Cohen details and clarifies many of the myths and misunderstandings that surround XQuery.
Implementing XQuery efficiently for relational databases is not trivial, because XQuery and SQL support different operations on quite different data models. At DataDirect, we emphasized performance and scalability in the design of our XQuery engine from the beginning, with a strong focus on relational data. This paper presents some of the techniques we use to generate efficient SQL for relational databases to implement XQuery for these data sources.
