object cache
解釋
目標緩存器-
Using the distributedmap interface, which is a simple interface for the dynamic cache, j2ee applications and system components can cache and share java objects by storing a reference to the object in the cache
Distributedmap介面是用於動態緩存的簡單介面，使用此介面，通過將引用存儲到緩存中的對象， j2ee應用程序和系統組件可以緩存和共享java對象。 -

A processing query is a query that returns a rowset containing the changes made to a table associated with an analysis services object since the last time the table was polled to incrementally update the molap cache for the object
處理查詢可以返回一個行集，其中包含自上次輪詢analysis services對象所關聯的表以來對該表所做的更改，以便對該對象的molap緩存進行增量更新。 -
Enterprise information system framework provides a series of reusable groupware, such as persistence layer which introduces dynamic value object 、 value list hander and command pattern, it encapsulates the detail of accessing database and affords the interface of different persistence layer framework ; basing on asynchronous javascript and xml ( ajax for short ), we develops the client validity check engine 、 dynamic cascading menu and common 、 dynamic tree structure groupware, as well as a set of tag library which include query 、 pagination 、 cache an so on. they reduce the code redundancy and predigests the development of interface layer enormously ; the security subsystem which is based on secure socket layer ( ssl for short ) and role - based access control ( rbac for short ) ensures the data security transmission and privilege control. furthermore, the model of enterprise application integration ( eai for short ) which based on web services, it supply some helpful explore for the sake of system integration and data communion for the future
企業信息系統框架提供了一系列可復用組件，例如採用動態vo 、值列表處理器以及命令模式的持久層組件，封裝了數據庫訪問細節，並為不同的持久層框架提供調用介面;基於ajax （ asynchronousjavascriptandxml ）技術的客戶端校驗引擎、動態級聯菜單以及通用動態樹型結構組件，一系列查詢、分頁、緩存等標簽庫則減少了表示層的代碼冗餘，簡化了表示層開發;基於ssl登錄以及基於角色的訪問控制的安全子系統則初步實現了數據安全傳輸和權限控制;此外基於web服務的企業應用集成模型為今後系統集成、數據共享提供了有益探索。 -
This paper stresses on discussing the architecture, access protocol and implementation mechanism based on xml and web services technologies, researches key technologies of metadata information service and data uniform access and management in database grid, designs and implements distributed mis subsystem and das subsystem, which support multi - domain management. mis can provides metadata information for the whole system, such as das and clients, it uses domain name 、 logical name and internal name of data object to uniformly name database resources in grid and implements name mapping mechanism and user view metadata information service and provides virtual organization and management of database resources. das can provide a scalable uniform data access by virtual organization and management of storage resources and multi - mode data share access mechanism, thus integrate database resources in grid and shields distribution and heterogeneity of resources and achieves transparent access. system adopts data access mechanism based on user request mapping to flexibly implement data access across multi domains, and adopts distributed data cache mechanism 、 security mechanism based gsi to provide high - performance secure data service for grid users
本文論述了griddaen - dai系統的邏輯結構、訪問協議、數據服務流程以及基於webservices 、 xml等技術的實現策略，重點研究數據庫網格中的元服務、數據統一訪問和管理等關鍵技術，設計和實現了支持多管理域的分散式元服務子系統和數據訪問服務子系統。其中元服務主要為整個系統提供各種元信息支持，它採用域名、數據對象的邏輯名稱、物理名稱和內部名稱對廣域環境下的數據庫數據進行了統一命名，實現了相應的名字映射機制和全局的用戶數據視圖服務，提供了數據庫資源的虛擬組織與管理方式;數據訪問服務通過提供可擴展的統一數據訪問和支持多種數據共享訪問模式，屏蔽了數據庫資源的分佈性和異構性，為用戶提供了統一透明的數據服務。 -
In the implementation, we try to avoid the known deficiencies. so we adopt the following mechanisms : an object cache, a configurable synchronize policy and a dead - lock - detection algorithem
為了避免上述缺陷，同時獲得較高的性能，我們在設計時除了考慮基本的需求，還重點研究了線程池、並發控制和死鎖檢測演算法。 -
First, the thesis constructs a object cache model based on asynchronous messaging model which can improve access efficiency of object by establishing duplicate locally for remote object, and studies a serious of key problem, and presents object duplication algorithm, object migration algorithm, duplicate consistency algorithm, etc. second, to keep up with the dynamic changes of performa
一個是基於異步消息模型進一步構建了對象緩沖模型，通過在本地建立遠程對象的副本，提高對象的訪問效率，研究並解決了其中一系列的關鍵問題，提出了對象復制演算法、對象遷移演算法、副本一致性維護演算法等。 -
Place the report object into asp. net cache only when the report has high shareability
只有在報表的可共享性較高時，才應將其放入asp . net cache 。 -
Then the structure and the function of each component of the cache system are shown. client semantic caching is different from traditional object caching in granularity and query processing. to get better cache hits in a semantic cache, a cache replacement strategy, called lwi ( least weight item ), is proposed
由於客戶語義緩存的粒度及基於緩存的查詢處理與傳統以頁或元組對象為粒度的緩存不同，因此本文提出語義緩存最小權值項lwi替換策略。 -
