Recent reverie, the non-formatting trend of data storage.Formatting tables to free XML storageSeveral years ago, several database vendors began to store XML databases. XML data as a self-describing semi-structured data provides a new data model for Web data management, if XML tag data is put into a certain structure, the retrieval, analysis, updating and output of data can be carried out in a more manageable, systematic and familiar environment. Therefore, we apply database technology to the fie

A database contains one or more named schemas, and the schema contains tables. The pattern also contains other named objects, including data types, functions, and operators. The same object name can be used in a different pattern without causing a conflict; For example, SCHEMA1 and MySchema can contain tables called mytable. Unlike databases, schemas are not strictly separate: a user can access objects in any pattern in the database to which he is con

A database schema (schema) is a logical container of data structures, called schema Objects (schema objects)Each database user has a pattern that is the same as the user name, such as an HR user with HR mode.In a product database, the owner of a pattern is typically a database application rather than a person.In a patt

DTDs are equivalent to data, and schemas are equivalent to collections. XML Schemas are created by a set of pre-defined XML elements and attributes. DTD does not follow XML syntax, DTD data type is limited, DTD is not extensible, DTD does not support space Named. Schema is based on XML syntax, can handle the processing of XML documents, extend the data type, can With custom data types, schema supports i
