It is unique in many ways as compared to the traditional BI platforms. As a data analysis tool, it always maintains the relationship between the data and this relationship can be seen visually using colors. It also shows the data that are not related. It provides both direct and indirect searches by using individual searches in the list boxes.QlikView's core and patented technology has the feature of in-memory data processing, which gives superfast result to the users. It calculates aggregations on the fly and compresses data to 10% of original size. Neither users nor developers of QlikView applications manage the relationship between data. It is managed automatically. Features of QlikViewQlikView has patented technology, which enables it to have many features that are useful in creating advanced reports from multiple data sources quickly. Following is a list of features that makes QlikView very unique.∙Data Association is maintained automatically- QlikView automatically recognizes the relationship between each piece of data that is present in a dataset.Users need not preconfigure the relationship between different data entities.∙Data is held in memory for multiple users, for a super-fast user experience- The structure, data and calculations of a report are all held in the memory (RAM) of the server.∙Aggregations are calculated on the fly as needed- As the data is held in memory, calculations are done on the fly. No need of storing pre-calculated aggregate values.∙Data is compressed to 10% of its original size- QlikView heavily uses data dictionary. Only essential bits of data in memory is required for any analysis.Hence, it compresses the original data to a very small size.∙Visual relationship using colors- The relationship between data is not shown by arrow or lines but by colors. Selecting a piece of data gives specific colors to the related data and another color to unrelated data.∙Direct and Indirect searches- Instead of giving the direct value a user is looking for, they can input some related data and get the exact result because of the data association. Of course, they can also search for a value directly.Download QlikViewThe Free Personal Edition of QlikView can be downloaded from QlikView Personal Edition. You need to register with your details to be able to download.After downloading, the installation is a very straightforward process in which you need to accept the license agreement and provide the target folder for installation. The screen shots given below describe the entire setup process.Start the Installation WizardDouble clicking the QlikViewDesktop_x64Setup.exe will present a screen to select the language of your choice.

Click "Finish".Verify the InstallationYou can verify the installation by going to the Windows Start menu and clicking on the QlikView icon. The screen appears as shown below.You are now ready to learn QlikView.3.QlikViewAs a leading Business Discovery Platform, QlikView is built with a very different approach to data discovery than other traditional platforms. QlikView does not first build a query and then fetch the result based on the query. Rather, it forms associations between different data objects as soon as it is loaded and prompts the user to explore the data in any way. There is no predefined data drill down paths. The data drill down paths can happen in any direction as long as the data is available and associated.Of course, a user can also play a role in creating the associations between data elements using data modeling approach available in QlikView.Architectural OverviewQlikView's architecture consists of a front end to visualize the processed data and a back end to provide the security and publication mechanism for QlikView user documents. The diagram given below depicts the internal working of QlikView. The architecture is discussed in detail below the picture.QlikViewFront EndThe Front end in QlikView is a browser-based access point for viewing the QlikView documents. It contains the QlikView Server, which is mainly used by the Business users to access the already created BI reports through an internet or intranet URL.Business users explore and interact with data using this front end and derive conclusions about the data. They also collaborate with other users on a given set of reports by sharing insights and exploring data together, in real time or off-line. These user documents are in the format .qvw, which can also be stored in the windows OS as a standalone document. The QlikView server in the front end manages the client server communication between the user and QlikView backend system.Back EndThe QlikView backend consists of QlikView desktop and QlikView publisher.The QlikView desktop is a wizard-driven Windows environment, which has the features to load and transform data from its source. Its drag and drop feature is used to create the GUI layout of the reports that becomes visible in the frontend. The file types, which are created by QlikView desktop are stored with an extension of .qvw. These are the files that are passed on to the QlikView server in the front end, which serves the users with these files. Also .qvw files can be modified to store the data-inly files, which are known as .qvd files. They are binary files, which contain only the data and not the GUI components. The QlikView publisher is used as distribution service to distribute the .qvw documents among various QlikView servers and users. It handles the authorization and access privileges. It also does the direct loading of data from data sources by using the connection strings defined in the .qvw files.4.QlikViewIn this chapter, we will get acquainted with the screens available to a user for doing various operations. We will learn the basic navigation and know the different functions performed by the icons available in QlikView.Getting Started ScreenThis screen is a gentle introduction to navigate around QlikView. This screen comes up when you start QlikView and keep the Show start page when launching QlikView option checked. If you scroll down the examples section in the left, you can click any of the examples like - Movies Database, Data Visualization etc. to invoke it and see how QlikView works. Feel free to click around! On moving to the right, you notice the Recent and Favourites link, which show all the recently visited QlikView documents and the documents you want to visit frequently.QlikViewMenu CommandsOn closing the ‘Getting Started’ window, we get the main interface with all the available Menu commands. They represent the entire set of features available in QlikView. Given below is an overview of each section of the Menu Commands.File MenuThis menu is used to create a new QlikView file and open the existing files from both local system and QlikView server. The important features in this menu are:∙Mail as attachment to email the currently open document as an attachment.∙Reduce Data to view only the report layout and database structure without any data.∙Table viewer option is used to see the structure of the tables, fields and their association in a graphical view.Edit MenuThis menu is used to carry out the editing options like copy, paste, cut and using format painter.

处理命令消息
你的文档类可能还会需要处理来自菜单项、工具栏按钮、快捷键产生的消息。 默认地，文档类通过序列化（serialization）处理由“文件”菜单中的“保存”、 “另存为”这两个菜单项的消息。其它影响到数据的消息，由你的文档类中的其 它成员函数处理。
文档类不能处理标准Windows消息（除了WM_COMMAND）
使用Document (3)
MFC中的序列化机制
数据持久化的基本思想就是对象能够向持久化存储空间写入自身的状态（通 常由其成员变量标记）。然后，对象可以从持久化存储空间读取（或称为反序列 化）其状态。一个关键点是，对象负责其自身状态的读写。所以要想持久化存储 一个类，这个类必须实现基本的序列化操作。 MFC提供的初始的实现方式是通过“文件”菜单栏中的“保存”与“另存为” 菜单项来保存文件到磁盘，通过“打开”菜单项来从磁盘读取文件。据此，你只 需很少的工作就可以实现一个文档功能来从磁盘读取文件，你需要做的主要是在 你的文档类中重载Serialize方法。MFC的向导已经为你搭建一个简单的重载Serialize 方法。
MFC用户接口之文档视图架构
概念说明
目录 1. Document-View Architecture 概述
2. Document-View Architecture 的优势 3. 使用Document 4. 使用View 5. 多文档类型
6. 多视图
7. 初始化与清理文档和视图 8. 为单类型文档增加多视图
比如，你可能想要重载OnUpdate以便在视图更新自身时做一些特殊的处理。
对于多页的文档，你可能想要重载OnPreparePrinting去初始化需要打印的页码及 其它信息到打印设置对话框上。
使用View (2)
一些继承自CView的现成可用的视图类
类 CCtrlView CEditView CRichEditView CListView 描述 类CTreeView, CListView, CEditView, 和 CRichEditView的基类。 CRichEditView的基类。允许输入和编辑文本。 包含一个CRichEditCtrl控件。不像CEditView，CRichEditView处理格 式化的文本。 包含一个CListCtrl控件。
CDaoRecordView
COleDBRecordView 这个视图包含一个CRowset对象。显示OLE DB记录。
使用View (3)
在视图中绘图（Drawing in a View）
几乎所有的绘图操作都通过视图中的OnDraw实现 *1。 通过文档类提供的方法获取数据； 通过调用MFC传递给OnDraw的与上下文无关的设备操作对象的成员函数来显示数据。
从文档获取数据，然后将任何数据变化后传给文档。
Document-View Architecture 概述（2）
View

GetDocument()
GetDocument() UpdateAllViews()
UpdateAllViews()
Document
Document-View Architecture 的优势
UpdateAllViews
当文档数据变化时，视图必须重绘以更新数据的显示。通过调用文档的 UpdateAllViews方法，来更新文档对应的所有视图。UpdateAllViews方法调用每一个视 图对象的OnUpdate方法。OnUpdate方法默认重绘视图的整个客户区域。你可以重载 OnUpdate方法以便只重绘指定的客户区域。
使用Document (2)
使用文档变量
1. 创建自己的文档类的成员变量。MFC提供了一组容器类型供使用； arrays lists maps CString CRect CPoint CSize Ctime
2. 为文档类设置get/set方法供存取变量；
3. Cview类通过GetDocument方法来获取文档指针，然后向/从文档存/取变量； 如果你不想为文档类设置公有方法，可以将视图类设置为文档类的友元类； 如果需要向文档频繁存取数据的话，最好将视图类设置为文档类的友元类；
使用View (4)
参与和处理用户输入
你的视图类中的其它成员函数处理所有的用户输入。一般定义消息处理函数去处理： 1. 由键盘鼠标产生的Windows消息（比如鼠标移动、键盘输入）； 2. 来自菜单、工具栏、快捷键的命令（包括操作剪贴板）；
视图需要处理哪些消息
什么样的消息需要由视图来处理？需依据你的应用程序的具体需求。 比如你可能需要处理直接用鼠标画图的操作，那么可能需要响应 WM_LBUTTONDOWN, WM_MOUSEMOVE, 和 WM_LBUTTONUP消息以代表画一段线条的
创建多文档类型概述
为了创建多文档类型，你需要从CDocument继承一个新的文档类，提供必要的文档信息，实 现需要的文档数据。 然后你需要让MFC框架知道这个额外的文档类型。你必须在你的应用程序的InitInstance函数 中，添加额外的AddDocTemplate方法
多视图1
同一文档对应多个相同类型的视图
Document-View Architecture 概述（1）
MFC应用程序向导默认地创建文档类与视图类的框架，MFC将数据管理分离到 这两类类型中。文档存储数据、管理数据打印以及协调数据的显示；视图显示数 据，以及管理与用户的交互。 在这种模式下，MFC的文档对象从持久化存储中读取数据，以及写入数据。文 档还需要提供一个面向数据存储区域（比如数据库）的接口。分离出来的视图对 象，管理数据的显示，从提取数据用于显示到窗口到用户选择和编辑数据。视图
文档类不像视图类，文档类不能处理标准Windows消息，除了WM_COMMAND （命令）。
使用View (1)
视图（View）的职责
视图的主要职责是将文档中的数据以图形化的形式显示给用户，并且响应用户的 输入并将它作用到文档上。关于编写视图类，你的任务是： 1. 编写你的视图类中的OnDraw成员函数来提取文档数据； 2. 连接适当的消息与Windows用户接口对象（如菜单）到视图类的消息处理成员函 数上； 3. 实现这些成员函数去响应客户的输入； 4. 另外，你可能想要重载一些CView的成员函数。 比如，你可能想要重载OnInitialUpdate去实现这个视图的特殊的初始化工作。
开始、继续画线、结束之类的动作。再比如，有时候，你可能需要让鼠标点击来做出
选择动作。在点击的时候，需要判断选中的是哪个对象，并且显示出不同的样式代表 对象被选中了。 你的视图可能还需要响应一些特定的用到剪贴板的菜单项，比如拷贝、粘贴、剪 切等。此类消息处理函数可能需要调用CWnd类中的剪贴板相关的成员函数。
支持映射多个视图到一个文档对象
应用场景举例：
Chart View
继承自CView
Spreadsheet View
继承自CView
UpdateAllViews
Document
用户通过Spreadsheet视图更新文 档中的数据。然后视图调用 Cdocument::UpdateAllViews方法， 将数据同步至Chart视图
初始化及清理概要说明
1. 框架初始化文档和视图；你初始化任何你增加的数据； 2. 框架在文档和视图关闭时执行清理工作；你必须用这些文档和视图中的成员函数 来释放你从堆里分配到的内存。
初始化和清理视图及文档(2)
初始化文档
文档会被以两种方式创建，所以你的文档类必须支持两种方式： 1. 用户可以通过“创建”菜单来创建一个新的空文档，此时你可以通过重载 CDocument的OnNewDocument成员函数来进行初始化； 2. 用户可以通过“打开”菜单来创建一个新的空文档，此时你可以通过重载 CDocument的OnOpenDocument成员函数来进行初始化；
当文档关闭的时候，框架调用它的DeleteContents成员函数。如果你为文档从堆里分 配了内存的话，这儿是最好的释放内存的地方。 注意：不要再文档的析构函数里去做释放内存的工作，因为在MDI模式下，文档对象 可能会被重用（即析构函数的调用时点可能远滞后于DeleteContents方法的调用时 点）；
同一文档对应多个不同类型的视图
多视图2
同一文档对应多个拥有相同类型的视图的边框（Frame）
初始化和清理视图及文档(1)
文档（包括边框窗口及视图）的生命周期
1. 在动态创建的时候，文档类的构造函数被调用； 2. 对于每一个文档，其OnNowDocument和OnOpenDocument会被调用； 3. 用户在文档的整个生命周期内与之交互。典型地，用户通过视图与文档的数据交 互，包括选择与编辑数据。视图将变化传递给文档去存储，然后更新视图。在这 个期间，文档和视图都需要处理消息； 4. 框架调用DeleteContents去删除文档特性相关的数据； 5. 文档的析构函数被调用；
数据在序列化机制中的角色
1. 通常，类类型的数据应该可以序列化自身；
使用Document (4)
跳过默认的序列化机制
有一些情况下MFC提供的默认的持久化机制不太适用，比如一个包含数据库的 应用程序，该应用程序只编辑超大文件的一部分，只写入文本文件等。 这种情况下，你可以以不同的方式重载Serialize方法，比如不使用CArchive对 象，而是使用CFile对象。框架会为你打开文件，然后你使用CArchive的GetFile方法 获取一个指向CFile对象的指针。 对于更加复杂和灵活的场景，你可以重载CWinApp类的OnOpenDocument和 OnSaveDocument成员函数。在这种场景下，你重载的Serialize方法将不做任何处理， 除非你想让它读写文件头以便在关闭文件时保持文件头是最新的。
文档在序列化机制中的角色
