SQLx is a vendor-agnostic, XML-based SQL data definition standard that offers the power of XML validation for your static SQL data. The SQLx framework utilizes a strongly-typed DDLx file to generate a XML Schema document that translates DDLx constructs into the XSD language. With the SQLx XSLT, the SQLx tool leverages the power of XML Schema Validation and provides a cohesive structured model to define SQL data (that conforms to your SQL schema, defined in a DDLx file).
