XML Database Doubts
Native XML databases struggle to compete with relational players.As XML becomes an increasingly important data interchange format, it makes sense to look at new ways of storing information directly in XML and using XML-based tools for data query and manipulation. However, what those tools will look like is still very much up in the air. A native XML database market is emerging to tackle this need. XML databases such as Ixiasoft Inc.s TextML Server, Software AGs Tamino and XYZFind Corp.s XYZFind Server allow data to be submitted in XML format, provide XML-based query languages and return data in XML format. However, eWeek Labs tests show that, just because program data is in XML format, a native XML database is not necessarily the right place to store it.
Generally speaking, XML databases just arent technically strong enough to compete with relational databasesXML databases lack numerous administrative, interoperability, programmability and manageability benefits provided by the big relational databases.
