  1. Having the dbms determine the optimal access path to the data lifts a heavy burden off the programmer s shoulders

    讓dbms確定到數據的最優存取路徑解除了程序員肩上沉重的負擔。
  2. Contributions in this paper mainly sh ow four points : 1 the structure characteristic of the received ds - cdma signal is analyzed in the presence of multi - path slow fading effect case for wireless mobile communication. according to this characteristic, four data - selected schemes based on chip - matched filter are presented from the perspective of energy and structure of signal. and the impact of these schemes on multiple - access interference ( mai ) and inter - symbol interference ( isi ) is analyzed

    本文的主要貢獻在於四個方面： 1 、針對無線移動通信系統中廣泛存在多徑慢衰落效應的情況，分析了ds - cdma系統中接收信號本身的結構特徵，根據這個特徵，在匹配濾波的基礎上，從能量與信號結構的角度提出了四種不同的數據採用方案，並分析了不同數據方案對多址干擾與碼間干擾的影響。
  3. The paper puts forward a combined - allocation - scheme based on the idea of constrained - block - allocation at the storing allocation strategy and gives disk - striping about the storing of big capacity disk array. in the study about the access path of the multi - media data, we introduce several kinds of representative multi - dimensions data index structure including k - d tree, r tree, vp tree and so on. ( 3 ) the research of multi - media database system architecture.

    在存儲分配策略上根據受限塊分配（ constrainedblock ? allocation ）的思想，本文提出了聯合分配模式（ combinedallocationscheme ） ；並針對大容量磁盤陣列的存儲給出了條形分配方案（ diskstriping ） ；在多媒體數據的存取路徑的探討中，重點介紹了幾種有代表性的多維數據索引結構，有k - d樹、 r *樹、 vp樹等。
  4. The paper is about how to analyze web server ' s log file and the technology used and tries to improve it in the following aspects : ( l ) this paper presents a simple processing model on mining web log based on xml storage and the corresponding solutions used to clean and transform log data. ( 2 ) according to the advantages of xml and the self - structure feature of log data, the paper proposes the novel idea that stores log data in xml form, furthermore it discusses the method and implementation on how to store xml - compliant log data into the database by the medium - grained storage means. ( 3 ) this paper addresses an improved algorithm called ufapa for mining user frequent access path on the basis of the algorithm apriori

    本文研究了web日誌挖掘中的相關技術，在以下幾方面進行了改進： （ 1 ）在web日誌挖掘模型的基礎上，對web日誌數據的清洗和轉換提出了相應的解決方法； （ 2 ）結合xml的優勢和web日誌數據的半結構化特點，提出用xml存儲日誌數據並探討了xml形式的日誌數據如何以中粒度方法實現在數據庫中存儲的方案； （ 3 ）結合用戶訪問路徑的特點以apriori演算法為基礎提出了一種改進的挖掘頻繁訪問路徑的ufapa演算法，介紹了演算法思想及演算法描述。
  5. In addition, the database can have a better understanding of the state of the data it stores, and thereby can produce a more efficient and dynamic access path to the data

    此外，數據庫可以更好地理解它存儲的數據的狀態，從而可以生成到數據的更有效和動態的存取路徑。
  6. This paper divides the web usage mining process into three main parts : data collecting consists of the three server logs - access, referer, and agent, the html files the make up the site, and registration data ; data preprocessing, includes data cleaning, user identification, session identification, path completion and transaction identification ; data analysis consists of mining frequent access paths and association rule. thinking about the amount of hits on homepage, this paper improves the algorithm of finding frequent items

    並結合網頁特點，考慮到主頁的點擊率的影響，對生成頻繁訪問瀏覽頁的演算法做了改進；在web使用挖掘的基礎上引入部分web結構挖掘，對挖掘瀏覽頁的關聯規則做了補充，在web結構挖掘基礎上挖掘出的相關瀏覽頁也推薦給用戶，在一定程度上提高了關聯規則的精確度。
  7. 1 index is hypothetical and cannot be used directly as a data access path

    1 =索引是假設的，不能直接用作數據訪問路徑。
