The schema pattern is similar to the software design pattern, but has a broader scope.Model-View-controller mode, also known as MVC mode (Model View controller).

Label:As a result of previous needs, the replication schema change was forbidden, and a field was added to the publication and not synced to the subscription, and now a field with the same name was added to the subscription, so how do you make the two fields of the publication and subscription a synchronous relationship? The following is a test of the change: the publication type is a updatable subscription for transactional replication , and other t
Label:Good logic design and physical design is the cornerstone of high performance, should be based on the system to execute the query statement to design the schema. This often requires a balance of factors. For example, anti-paradigm design can speed up certain types of queries, but it may also slow down other types of queries. For example, adding a count table and a summary table is a good way to refine the query. However, the maintenance costs of
The difference between Oracle Schema and User can be seen from the definition that Schema is a set of database objects. In order to distinguish each set, we need to name this set. These names are the nodes with similar user names that we see in the Enterprise Manager Solution. These nodes with similar user names are actually a schema,

The XML XML schema is the recommended standard of the World Wide Web Consortium, which was officially released in May 2001, and has now finally been laid down for years of large-scale discussion and development, becoming the preferred data modeling tool in the globally recognized XML environment.
Because XML is a subset of SGML (the standard Universal Markup Language), it also inherits SGML's DTD for modeling. The advantage of using DTDs is that you c

Both XML schema and DTD are used for document verification, but there are some differences between them. The former is more accurate and flexible:
DTDDTD does not comply with XML syntaxThe DTD cannot be expanded.DTD does not support namespace applicationsThe DTD does not provide powerful data type support and can only represent simple data types.
SchemaSchema is fully based on XML syntaxCan be processed using tools for processing XML documentsGreatly
A database contains one or more naming modes. The schema also contains tables. The schema also contains other named objects, including data types, functions, and operators. The same object name can be used in different modes without causing conflicts. For example, both schema1 and myschema can contain tables called mytable. Unlike databases, the mode is not strictly separated: a user can access objects in a

Inheritance of object classesA new object class can be defined with the parent class and additional added or modified attributes. All object classes are inherited from abstract object class and are called top inheritance. They can also be inherited from other object classes. Abstract object class defines
