The user may then examine search results in multiple formats, allowing the user to view as much of the document as the user deems necessary. DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram illustrating an information retrieval system of the invention。今天所使用的多數系統實際上采用的是同一方式。然而，當面對變得更大來源分組或需要更加全面的查詢結果時，這個問題就更加明顯，人們尋找的信息經常面對大量未組織的結果集合，這樣就需要增加過濾查詢的重要任務。然后提供給相對于用戶相關查詢的結果與在該查詢結果中的每個類別相關文檔數量的統計。例如，一本典型的商業(yè)雜志也許包含信息的幾個類型，例如社論、規(guī)則專欄、特寫、新聞、產品公告和事件日歷。查詢結果的獨特類設置介紹不但極大地減少了反復查詢多個數據庫所付出的時間和費用，并且可以做到高效率檢索相關的查詢結果?；诜诸愒~典和嵌入搜索策略的信息庫，允許用戶使用“自然”語言來進行專業(yè)的信息查詢。用戶發(fā)出一個命令然后請求，例如“VI CO 1”，查驗從名單挑選的完全文件，在這種情況下，給關于身分專家的完全信息和證件。只要每次查詢到一個原文歸檔數據的固有部分，所有建立的文檔就能返回到其組織過程。即使你按照這樣操作，也有可能錯過相關的答案，因為所有可能相關的數據庫或信息來源并不在每一次搜索查詢中。關鍵詞：信息管理；檢索系統；面向對象1. 簡介信息的存儲，查詢和檢索系統,主要應用原文檔數據比較大的文檔，利用搜索條件和索引字段可以快速查詢結果。 that is, users log on (through a puter terminal or personal microputer, and typically from a remote location), select a source of information (., a particular database) which is usually something less than the plete domain, formulate a query, launch the search, and then review the search results displayed on the terminal or microputer, typically with documents (or summaries of documents) displayed in reverse chronological order. This process must be repeated each time another source (database) or group of sources is selected (which is frequently necessary in order to insure all relevant documents have been found).Additionally, this process places on the user the burden of organizing and assimilating the multiple results generated from the launch of the same query in each of the multiple sources (databases) that the user needs (or wants) to search. Present systems that allow searching of large domains require persons seeking information in these domains to attempt to modify their queries to reduce the search results to a size that the user can assimilate by browsing through them (thus, potentially eliminating relevant results). In many cases end users have been forced to use an intermediary (., a professional searcher) because the current collections of sources are both plex and extensive, and effective search strategies often vary significantly from one source to another. Even with such guidance, potential relevant answers are missed because all potentially relevant databases or information sources are not searched on every query. Much effort has been expended on refining and improving source selection by grouping sources or database files together. Significant effort has also been expended on query formulation through the use of knowledge bases and natural language processing. However, as the groupings of sources bee larger, and the responses to more prehensive search queries bee more plete, the person seeking information is often faced with the daunting task of sifting through large unorganized answer sets in an attempt to find the most relevant documents or information. OF THE INVENTION The invention provides an information storage, searching and retrieval system for a large domain of archived data of various types, in which the results of a search are organized into discrete types of documents and groups of document types so that users may easily identify relevant information more efficiently and more conveniently than systems currently in use. The system of the invention includes means for storing a large domain of data contained in multiple source records, at least some of the source records being prised of individual documents of multiple document types。在此次畢業(yè)設計當中，我不僅學會了不少專業(yè)知識還從指導老師的身上學到了很多東西。另外，在整個系統的開發(fā)過程中，由于時間比較倉促，難免在系統的分析方面有不到位的情況，在程序設計方面有考慮不周全的地方，因此該系必然存在著一些或多或少的缺陷和不足，甚至可能難以滿足特定用戶的特殊要求。 (0, id)。 }當該課程可選時，可以設置該課程為不可選，通過該課程的ID號，從課程信息表中修改課程的可選性。 } if((name)!=null){ sql += AND like 39。 }通過專業(yè)的ID號，設置專業(yè)已結業(yè).核心代碼為：public void updateIsFinish(Integer id) {Query q = getSession().createQuery(UPDATE Specialty s SET =?
