Specifies how to handle existing schema mappings when performing a 操作時(shí)如何處理現(xiàn)有的架構(gòu)映射。
Xml schema mapping xml模式映射
To an instance of the data source that matches the schema mapped to the document, such as an instance of the typed 綁定到與映射到文檔的架構(gòu)匹配的數(shù)據(jù)源的實(shí)例,如創(chuàng)建的類型化
Users are not required to understand the property syntax; it is handled automatically through internal schema mapping 處理。用戶無(wú)需理解屬性語(yǔ)法;它將通過(guò)內(nèi)部架構(gòu)映射自動(dòng)處理。
If such a principal creates an object without specifying a schema, sql server will create an implicit user and schema mapped to the windows principal 如果這樣的主體在不指定架構(gòu)的情況下創(chuàng)建對(duì)象,則sqlserver將創(chuàng)建映射到windows主體的隱式用戶和架構(gòu)。
Yes, all of the models in figure 1 could be improved, but i needed a simple example that showed how different object schemas mapping to the same data schema 是的,圖表1中的所有模型都可以改進(jìn),但是我只是需要一個(gè)展示不同對(duì)象模式怎樣映射到同一數(shù)據(jù)模式的簡(jiǎn)單例子。
A schema mapping templete is defined by the segmental modeling for xml schema and the relational schema will be transformed to xml schema according to this schema mapping templete 基于該模版將關(guān)系模式轉(zhuǎn)化為xmlschema模式的描述,完成模式映射。該算法為論文的創(chuàng)新點(diǎn)之一。

There are two main factors to influence materialized views in pdmss . one is that schema mappings between peers are changed, and the other is that peers update their data 在pdms中有兩個(gè)主要因素影響物化視圖:第一是peer之間的模式映射發(fā)生了改變,第二是有peer更新了它的數(shù)據(jù)。
In chapter 3, the technique of schema mapping between different step application protocols is discussed . the significance of schema mapping between step application protocols is stated 闡述了step模式間映射的意義,并對(duì)用express-x進(jìn)行step模式映射的技術(shù)難度做了一定的分析。
