  1. In the preprocessing stage the method of user and session identification often adopt heuristic algorithm for the being of cache and agent. this induce the uncertainty of data resource. the cppc algorithm avoid the limitation and has no use for complicated hash data structure. in this algorithm, by constructing a userld - url revelant matrix similar customer groups are discovered by measuring similarity between column vectors and relevant web pages are obtained by measuring similarity between row vectors ; frequent access paths can also be discovered by further processing of the latter. experiments show the effectiveness of the algorithm. in the fourth part, this thesis bring some key techniques of data mining into web usage mining, combine the characteristic of relation database design and implement a web usage mining system wlgms with function of visible. lt can provide the user with decision support, and has good practicability

    本文演算法避免了這個缺陷,且不需要復雜的hash數據結構,通過構造一個userid - uel關聯矩陣,對列向量進行相似性分析得到相似客戶群體,對行向量進行相似性度量獲得相關web頁面,對後者再進一步處理得到頻繁訪問路徑。實驗結果表明了演算法的有效性。第四是本文將傳統數據挖掘過程中的各種關鍵技術,引入到對web使用信息的挖掘活動中,結合關系數據庫的特點設計並實現了一個具有可廣西人學頎士學位論義視化功能的web使用挖掘系統wlgms 。
  2. However, the farther analysis in the paper indicates that the strategy of parameter configuration in current connection pool technique is static state with 1 - order enactment while initializes connection pool without self - optimized adjustment according as the variety of application demand, the operation results of high use frequency database are not cached and users visit the same database independently. the multi - propose connection strategy cannot control the database operation for the same transaction and cannot ensure the acid attribute, etc. in according with the defections mentioned above, the service technique of self - optimized connection pool is presented in this paper and the composing structure for self - optimized connection pool is designed, then, some strategy in dynamic parameters adjustment, transaction management and data cache for connection pool is improved

    然而,通過本文的研究分析,現有數據庫連接池技術的參數配置策略是靜態的,連接池初始化時進行一次設定,不能根據應用需求的變化而動態調整;連接池的核心管理機制中,沒有對使用頻率較高的數據庫操作結果進行緩存,多個用戶依然各自獨立地完成相同的數據庫訪問;使用的連接復用策略無法控制屬于同一個事務的多個數據庫操作,不能保證事務的acid屬性等。
  3. The network fluxes are classified as secure, suspicious, or repulsive using the rules collection, and only the suspi - cious ones will be handled to next stage. furthermore, using the idea of cache, the paper proposed the states collection structure

    訪問控制採用了狀態檢測防火墻的設計技術,通過規則表把網路流量劃分成信任?受懷疑?拒絕的類別,只有受懷疑的流量才會交給下一個步驟來處理。
  4. 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。
  5. The goal we must achieve, when designing distributed parallel file system, was analyzed also. the thesis present the logic structure of dpfs, the structure and the flush strategy of the module of directory cache and its role in the read - write operation, duplicate table ' s physical and logical structure, the management and synchronization algorithm of the duplicate table, and the model and the management algorithm of the module of intelligent duplicate management. also the effects that dpfs exerts to the system reliability and the read and write performance compared to ext2 were analyzed

    本文首先介紹了數據存儲的發展概況與新的需求,分散式文件系統對其發展的重要影響以及設計分散式文件系統需要考慮的各種問題;然後分析了為滿足分散式并行服務器的功能需求, dpfs應實現的目標;接著介紹了dpfs設計的總體邏輯結構,目錄緩存管理模塊的結構設計、刷新策略以及該模塊在文件讀寫重定向中的作用,副本表的邏輯、物理結構、對其緩存的管理和同步演算法的實現,以及副本智能管理的設計模型及其管理演算法的設計與實現,還分析了dpfs對系統可靠性的影響以及在讀寫文件時與ext2文件系統性能的比較。
  6. 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。
