Refresh Your Java - Before Java Interview
We are Agile, believe in less Documentation - Only Quick notes (Java Interview Questions) of Java/J2ee Read more....
Both Document Type Definitions (DTD's) and
XML Schemas (XSD's, also known as WXS)
are
industry-standard ways to define XML-based data models, and
you'll find many tools
and utilities for working
with both DTD and XML Schema in Stylus Studio/XML Spy.
| DTD | XSD |
| Support for primitive (built-in) data types (eg: xsd:integer, xsd:string, xsd:date, and so on), which facilitates using XML in conjunction with other typed-data, including relational data. | |
|
The ability to define custom data types, using object-oriented
data modeling principles: encapsulation, inheritance, and
substitution. Compatibility other XML technologies, for example, Web services, XQuery, XSLT and other technologies can optionally be schema-aware. |
|
| Better Performamce you must also consider the fact that the XML Schema is an XML document. It has an XML Namespace to refer to, and an XML DTD to define it. This is all overhead. When a parser examines the document, it may have to link this all in, interperate the DTD for the Schema, load the namespace, and validate the schema, etc., all before it can parse the actual XML document in question. If you’re using XML as a protocol between two systems that are in heavy use, and need a quick response, then this overhead may seriously degrade performance |
This Portal is intended to put all Java/J2ee related topics at one single place for quick referance, not only Technical , but also the Project Management Related thing such as Development Process methodoogies build process, unit testing etc.,
This Portal has More than 500 Java Interview Questions (also could be Considered as Quick Notes) very neatly separated topic by topic with simple diagrams which makes you easily understandable. Importantly these are from our Realtime expericance.
