free ebook and tutorial - Querying XML Views of Relational Data
XML has emerged as the standard data exchange format for Internet-based business applications. This has created the need to publish existing business data, stored in relational databases, as XML.

free ebook and tutorial - Exploiting PHP code injection
This paper will demonstrate the use of a PHP code injection exploit, as part of the GIAC Incident Handler Certification (GCIH). We will study a specific vulnerability found in a PHP eval() statement, that will grant the attacker with a remote access on the vulnerable device. Then, we will show how to prevent this attack from happening. After giving all the details of this exploit, an incident handling process will be proposed. Although performed in a lab environment, this is a real attack that could be exploited over any open network, such as the Internet.

free ebook and tutorial - XML Metadata Services
As the Service Oriented Architecture (SOA) principles have gained importance, an emerging need has appeared for methodologies to locate desired services that provide access to their capability descriptions. These services must typically be assembled into short-term service collections that, together with code execution services, are combined into a meta-application to perform a particular task. To address metadata requirements of these problems, we introduce XML Metadata Services to manage both stateless and stateful (transient) metadata.
