【Data】数组的顺序表示与实现
一、数组的定义 几乎所有的程序设计语言都把数组类型设定为固有类型。 以抽象数据类型的形式讨论数组的定义和实现,可以让我们加深对数组类型的理解。 数组的定义: ADT Array{ 数据对象:ji=0,...,bi-1,i=1,2,...,n; D={aj1j2...jn|n(>0)称为数组的维数,bi是数组第i维的长度,ji是数组元素的第i维下标,aj1j2...jn (-ElemSe

Data, Data, Everywhere
You've been asked to make a simple text-based <em>data</em>base that can store any number of fields associated with records. IDs can contain letters, numbers, dashes (-), and slashes (/), and are case-sensitive. The standard <em>data</em> format for input and output is:nrecord-idnfield-idnsome <em>data</em> herenterminated withna single periodn.nnThere are NO blank lines between entries.nnSome commands have lists of record IDs or field IDs. These are comma-separated lists of IDs (no spaces) that specify the order of the output. * can be specified instead of a list of IDs. If * is specified for the record IDs, treat it as a comma-separated lexicographically sorted list of all the record IDs with at least one field in the <em>data</em>base. If * is specified for the field IDs, treat it as a comma-separated lexicographically sorted list of all the field IDs defined by at least one record in the <em>data</em>base.nnThe list of commands and their parameters follows:nnCommand Descriptionnshow For the specified records, display the values of the specified fields. This command takes two parameters, a list of record IDs and a list of field names. Both are comma-separated lists (no spaces) which specify which entries to display and in what order to display them. Output should follow the standard entry format and should be terminated by a line containing a single asterisk.nIf a record does not have <em>data</em> for a field, then display the following entry for that record:nnrecord-idnfield-namenNO DATAn.nnrem The program should ignore the text.nappend Read in text and add it to the end of the specified entry, creating the entry if necessary. Input is terminated with a single period.ndelete For the specified records, delete the values of the specified fields. This command takes two parameters, a list of record IDs and a list of field names.ndone Stop processing this list of commands.nnInputnnRead commands from the input, one command per line. There will be at most 50,000 lines in the input (including any read files), a mix of commands and <em>data</em>. IDs will be at most 64 characters long. There will be at most 10,000 field IDs and 10,000 record IDs defined at any given time, although more may be defined after the old IDs have been deleted. Each line will be at most 255 characters long. Record field <em>data</em> will be at most 2,000 lines long.nnnOutputnnnOnly the show command produces output. Print the output in the standard <em>data</em> format to the standard output stream.nnThe program should finish the given input within 60 seconds.nnnSample Inputnnappend team-bar prob-bn1400 Accepted.n.nappend team-foo prob-an1305 Wrong answer.n.nshow team-foo,team-bar *nappend team-foo prob-an1402 Accepted.n.nrem Hmm...ndelete team-bar *n.nshow * *ndonennnSample Outputnnteam-foonprob-an1305 Wrong answer.n.nteam-foonprob-bnNO DATAn.nteam-barnprob-anNO DATAn.nteam-barnprob-bn1400 Accepted.n.n*nteam-foonprob-an1305 Wrong answer.n1402 Accepted.n.n*

Data Mining with Big Data
This paper presents a HACE theorem that characterizes the features of the Big Data revolution, and proposes a Big Data processing model, from the <em>data</em> mining perspective. This <em>data</em>-driven model involves demand-driven aggregation of information sources, mining and analysis, user interest modeling, and security and privacy considerations. We analyze the challenging issues in the <em>data</em>-driven model and also in the Big Data revolution.

Data Warehousing in the Age of Big Data
Data Warehousing in the Age of Big Data (The Morgan Kaufmann Series on Business Intelligence) Data Warehousing in the Age of the Big Data will help you and your organization make the most of unstructured <em>data</em> with your existing <em>data</em> warehouse. As Big Data continues to revolutionize how we use <em>data</em>, it doesn’t have to create more confusion. Expert author Krish Krishnan helps you make sense of how Big Data fits into the world of <em>data</em> warehousing in clear and concise detail. The book is presented in three distinct parts. Part 1 discusses Big Data, its technologies and use cases from early adopters. Part 2 addresses <em>data</em> warehousing, its shortcomings, and new architecture options, workloads, and integration techniques for Big Data and the <em>data</em> warehouse. Part 3 deals with <em>data</em> governance, <em>data</em> visualization, information life-cycle management, <em>data</em> scientists, and implementing a Big Data-ready <em>data</em> warehouse. Extensive appendixes include case studies from vendor implementations and a special segment on how we can build a healthcare information factory. Ultimately, this book will help you navigate through the complex layers of Big Data and <em>data</em> warehousing while providing you information on how to effectively think about using all these technologies and the architectures to design the next-generation <em>data</em> warehouse. Learn how to leverage Big Data by effectively integrating it into your <em>data</em> warehouse. Includes real-world examples and use cases that clearly demonstrate Hadoop, NoSQL, HBASE, Hive, and other Big Data technologies Understand how to optimize and tune your current <em>data</em> warehouse infrastructure and integrate newer infrastructure matching <em>data</em> processing workloads and requirements

单继承在没有多态的情况下比较简单,只是把基类堆叠到派生类上边,组成一个新的类。注意基类的alignment造成的调整边界产生的内存使用并不会消失。class A{ public: char a; }; class B: public A{ //B的大小是8 public: int c; };加上多态后需要在object中导入一个vptr,加入的vptr可以放在尾部(与C stru

presenting big data with interactive data
Analyzing big <em>data</em> is not easy with lightweight tools. Recent <em>data</em> leaks have shown that exploring <em>data</em> with traditional methods takes too much time. This thesis investigated whether today's <em>data</em> visualization JavaScript libraries can create agile and interactive user interfaces. Browsers are facing hard times when massive amounts of <em>data</em> are analyzed on the screen. The study was done in three parts during the year. The history of <em>data</em> visualization was studied first and after that the most well-known cases in the industry were investigated. Web technologies that have boosted the development were also under the research. In the second phase, the best JavaScript libraries supporting interactive <em>data</em> visualization were selected. The examples provided by the libraries were studied in terms of speed, user friendliness and future development. At the end of the studies, the best JavaScript libraries were heavily pushed to handling 100,000 elements on the screen. The survey material used was massive and open <em>data</em> provided by the San Francisco City and the County. This huge <em>data</em> file contained property information from San Francisco City area. The study focused on the interactive side of the issue. This means how many nodes and edges visualization can take so that the user could still analyze the <em>data</em> smoothly. Interactivity was the key element of the study, so the drawing capability of static nodes and edges was not measured. The number of edges used in the tests was held in 500 pieces at all times. The study also marked out how the performance of the computers or the different browsers affected the results. The final results were in line with the technical specifications JavaScript libraries promised. Today’s JavaScript libraries are able to produce, together with the modern Internet browsers, a sufficient number of elements to the screen without slowing down. Best libraries are also able to offer good editing opportunities to users who lack sufficient computing skills.
