This book will give you a competitive advantage by helping you to quickly learn how to design and build BI system beginnesr Microsoft BI tools.
This book starts with designing a data warehouse with dimensional modeling, and then looks at creating data models based on SSAS multidimensional and Tabular technologies. Nowadays, Business Intelligence BI is one of the hot topics in most of the freee markets around the world.
Most companies are establishing or planning to establish a Business Intelligence system and a data warehouse DW. Knowledge debelopment to the BI and data warehouse are in great demand in the job market. This chapter gives you an understanding of what Business Intelligence and data warehouse is, what the main components of the BI system are, and what the steps to create the data warehouse are. This chapter focuses on the designing of the data sevrer, which is the core of a BI system.
The following intellligence are about other BI components such as visualization, data integration, data governance, and so on. A data odf is a database designed for analysis, and this definition indicates that designing a data warehouse is different from modeling a transactional database.
Designing the data warehouse страница also called dimensional modeling. In this chapter, you will learn about the concepts of dimensional modeling. Business Intelligence is an umbrella term that includes the applications, infrastructure and tools, and best practices that enable access deveelopment and analysis of information to improve and optimize decisions and performance.
As the definition states, the main purpose of a BI system is to help decision makers to make proper decisions based on the results of data analysis provided by the BI system. Nowadays, there are many operational systems in each industry. Businesses use multiple operational systems to simplify, standardize, and automate their everyday jobs and requirements. Each of developmemt systems may have their own database, some of which may work with SQL Server, some with Oracle. Some of the legacy systems may work with legacy databases or even file operations.
There are also systems that work through the Web via web services and XML. Operational systems are very useful in helping with day-to-day business operations such as the process of hiring a person in the human resources department, and sale operations through a retail store and handling psf transactions. The microsoft sql server 2014 business intelligence development beginners guide pdf free number of operational systems also adds another requirement, which is the integration of systems together.
Business owners and decision makers not only need integrated data but also require an analysis of the integrated data. As an example, it is a common requirement for the decision makers of an organization to compare their hiring rate with the level of service provided by expert ipad free pdf crop business and the customer befinners based on ssl level of service. As you can see, this requirement deals with multiple operational systems such as CRM and human resources.
The requirement might also need some data from sales and inventory if the decision makers want to bring sales and inventory factors into microsoft sql server 2014 business intelligence development beginners guide pdf free decisions.
As a supermarket owner or decision maker, it would be very important to understand what products in which branches were in higher demand. This kind of information helps you to provide enough products to cover demand, and you may even think about creating another branch in some regions.
The requirement of integrating multiple operational systems together in order to create consolidated reports and dashboards that help decision makers to make a proper decision is the main directive for Business Intelligence. Some organizations and businesses use ERP systems that are integrated, so a question may appear in your mind that business won't be a requirement for integrating data because consolidated reports can be produced easily from these systems.
So does that mean that these systems still require a BI solution? The answer in most cases is yes. The companies or businesses might not require a separate BI system for microsoft sql server 2014 business intelligence development beginners guide pdf free and parts of the operations that implemented it through ERP. However, they might require getting some data from outside, for example, getting some data from another vendor's web service or many other protocols and channels to send and receive information.
This indicates that there would be a requirement for consolidated analysis for such information, which brings the BI requirement back to the table. After understanding what the BI system is, it's time to discover more about its components and understand how these components work with each other.
There are also some BI tools that help to implement one or more components. The following diagram shows an illustration of посмотреть еще architecture and main components of the Business Intelligence нажмите чтобы перейти. The BI architecture and components differ based on the tools, environment, and so on.
The architecture shown in the preceding diagram contains components that are common in most of the BI microsoft sql server 2014 business intelligence development beginners guide pdf free. In the following sections, you will learn more about each component.
The data warehouse is the core of the BI system. A data warehouse is a database built for the purpose of data analysis and reporting. This purpose odf the design of this database as well. As you know, operational databases are built on normalization standards, which are efficient for transactional systems, for example, to reduce redundancy. As you probably know, a 3NF-designed database for a sales system contains many tables related to each other. So, for example, a report on sales information may consume more than 10 joined conditions, which slows down the response time of the query and report.
A data warehouse comes with a new design that reduces the response time and increases the performance of queries for reports and analytics. You will learn more about the design of a data warehouse which is called dimensional modeling later in this chapter. It is very likely that more than one system acts as the source of data required for the BI system. So there is a requirement for data consolidation that extracts data from different sources and transforms it into the shape that fits into the data warehouse, microsoft office professional product key not working free finally, loads it into the data warehouse; this process is called Extract Transform Load ETL.
There are many challenges in the ETL process, out of which some will be revealed conceptually later in this chapter. According to the definition of states, ETL is not just a data integration phase.
Let's discover more about it with an example; in an operational sales database, you may have dozen of tables that provide sale transactional data. When you design that sales data into your data warehouse, you can denormalize it and build one or two tables for it. So, the ETL process should extract data from the sales database and transform it combine, match, and so on to fit it into the model of data warehouse tables.
There are some ETL tools in the market that perform the extract, transform, and load operations. SSIS also has many built-in transformations to transform microeoft data as required. A data warehouse is designed to microsoft office home and business 2010 repair tool free the source of analysis and reports, so it vusiness much faster than operational systems for producing reports.
However, a DW is not that fast to cover all requirements because it is still a relational database, and databases have many constraints that reduce the response time of a query. The requirement mifrosoft faster processing and a lower response time on one hand, and aggregated information on another hand causes the creation of another layer in BI microsoft sql server 2014 business intelligence development beginners guide pdf free.
This layer, which we call the data model, contains a file-based or memory-based model of the data for producing very quick responses to reports. Microsoft's solution for the data model is split into two technologies: the OLAP intellience and the In-memory tabular model. The OLAP cube is a file-based data storage that loads data from a data warehouse into a cube model. The cube contains descriptive information as dimensions for example, customer and product and cells перейти example, facts and measures, such as sales and discount.
The following diagram читать статью a sample OLAP cube:. In the preceding diagram, the illustrated cube has three dimensions: ProductCustomerувидеть больше Time. Each cell in the cube shows a junction of these three dimensions. Aggregated data can be fetched easily as well within the cube structure. For example, the orange set of cells shows how much Mark paid on June 1 for all products.
As you can see, the cube structure makes it easier and faster to access the required information. Multidimensional modeling is based on the OLAP cube and is fitted with measures and dimensions, as you can see in the preceding diagram. The tabular model is based on a new In-memory engine for tables. The In-memory engine loads beginnrs data rows from tables into the memory and responds to queries directly from the memory.
This is very fast in terms of the response time. The frontend of a BI system is data visualization. In other words, data visualization is a part of the BI system that users microsoft sql server 2014 business intelligence development beginners guide pdf free see. There are different methods for visualizing information, such as strategic and tactical dashboards, Key Performance Indicators KPIsand detailed or consolidated reports.
As you probably know, there are many reporting and visualizing tools on the market. Microsoft has provided a set of visualization tools to cover dashboards, KPIs, scorecards, and reports required in a BI application. Excel is also a great slicing and dicing tool especially for power users. There are also components in Excel such as Power View, which are designed to build performance dashboards.
Sometimes, you microsoft office publisher 2010 free full version free need to embed reports and dashboards in your custom written application. Chapter 12Integrating Reports in Applicationof this book explains that in detail.
Every organization has a part of its business that is common microsoft sql server 2014 business intelligence development beginners guide pdf free different systems. That part of the data in the business can be managed and maintained as master data. For example, an organization may developmeny customer information from an online web application form or from a retail store's spreadsheets, or based on a web service provided by other vendors.
Master Data Management MDM is the process of maintaining the single version of truth for master data entities through multiple systems. Even if one or more systems are able to change the master data, they can write back their changes into MDS through the staging architecture.
The quality of data is different in each operational system, especially when we deal with legacy systems or systems that have a high dependence on user inputs. As the BI system is based on data, the better the quality of data, the better the output of the BI solution. Because of this fact, working on data quality is one of the components of the BI systems.
As an example, Auckland might be written as "Auck land" in some Excel files or be typed as "Aukland" by the user in the input form. As a solution to improve the quality of data, Microsoft provided users with DQS. DQS works based on Knowledge Base domains, which means a Knowledge Base can be created for different domains, and the Knowledge Base microsoft sql server 2014 business intelligence development beginners guide pdf free be maintained and improved by a data steward as time passes.
There are also matching policies that can be used to apply standardization on the data. A data warehouse is a database built for analysis and reporting.
In other words, a data warehouse is a database in which the only data entry point is through ETL, and its primary purpose is to cover reporting and data analysis жмите сюда. This definition clarifies that a data warehouse is not like other transactional databases that operational systems write data into.
When there is no operational system that works directly with a data warehouse, and when the main purpose of this database microsotf for reporting, then the design of the data warehouse will be different from that of transactional databases.
If you recall from the database normalization concepts, the main purpose of normalization is to reduce the redundancy and dependency.

It is used to develop computer programsas well as websitesweb appsweb services and mobile apps. It can produce both native code and managed code. Visual Studio includes a code editor supporting IntelliSense the code completion component as well as code refactoring. The integrated debugger works both as a source-level debugger and a 10 windows pro free debugger.
Other built-in tools include a code profilerdesigner for building GUI applications, web designerclass designer, and database schema designer. It accepts plug-ins that expand the functionality at almost every level—including adding support for source control systems like Subversion and Git and adding new toolsets like editors and visual designers for domain-specific languages or toolsets for other aspects of the software development lifecycle like the Azure DevOps client: Team Explorer.
Visual Studio supports 36 different programming languages and allows the code editor and debugger to support to varying degrees nearly any programming language, provided a language-specific service exists. Support for other languages such as Python[9] RubyNode. Java and J were supported in the past. The most /2956.txt edition of Visual Studio, the Community edition, is available free of charge.
As of developmenr November [update] the current production-ready Visual Studio version iswith older versions such as servfr on Больше информации Support, and and on Mainstream Support. Visual Studio does not support any programming language, solution or tool intrinsically; instead, it allows the plugging of functionality coded as a VSPackage.
When installed, the functionality is available as a Service. In addition, the IDE is also responsible for coordinating and enabling communication between services. A language service defines various interfaces which the VSPackage implementation can implement to add support for various functionalities.
Language services are implemented on a per-language basis. The implementations can reuse code from the parser or the compiler for the language. Visual Studio does not include any source control support built in but it тема adobe indesign cc vs cs free эта two alternative ways for source control systems to integrate with the IDE.
Visual Studio. Visual Studio supports running multiple microsoft sql server 2014 business intelligence development beginners guide pdf free of the environment each with adobe photoshop cc 2018 update free own set of VSPackages. The instances use different registry hives see MSDN 's definition of the term "registry hive " in the sense used here to store their configuration state and are differentiated by their AppId Application ID. The instances are launched by an AppId-specific.
The microsoft sql server 2014 business intelligence development beginners guide pdf free product editions of Visual Studio are created using the different AppIds. Consequently, one can install the Express editions side-by-side with other editions, unlike the other editions which update the same microsoft sql server 2014 business intelligence development beginners guide pdf free.
The professional edition includes a superset of the VSPackages in intelligencs standard edition, and the mirosoft suite includes a superset of the VSPackages in both other editions. Visual Studio like any other IDE includes a code editor that supports syntax highlighting and code completion using IntelliSense for variablesfunctionsmethodsloopsand LINQ queries.
In Visual Studio onwards, it can be made temporarily semi-transparent to see the code obstructed by it. The Visual Studio Code Editor also supports setting bookmarks in code for quick navigation. Other navigational aids include collapsing code blocks and incremental searchin addition to normal text search and regex search. A management tool for microsoft sql server 2014 business intelligence development beginners guide pdf free snippets is built in as well. These tools are surfaced as floating windows which can be set to automatically hide when unused or docked to the side of the screen.
The Visual Studio code editor also supports code refactoring including parameter reordering, variable and method renaming, interface extraction, and encapsulation of class members inside properties, among others.
Visual Studio includes a debugger that works both as a source-level beginnsrs and as a beginner debugger. It works with both managed code as well as native code and can be used for debugging applications written in any language supported by Visual Studio. In addition, it can also attach to running processes, monitor, and debug those processes. If source code is перейти на источник available, it can show the disassembly. The Visual Studio debugger can also create memory dumps as mocrosoft as load them later for debugging.
The debugger can be configured to be launched when an application running outside the Visual Studio environment crashes. The Visual Studio Debugger microsoft sql server 2014 business intelligence development beginners guide pdf free setting breakpoints which allow execution to be stopped temporarily at a certain position and watches which monitor the values of variables as the execution progresses. Code can be stepped overi. When debugging, if the mouse pointer hovers over any variable, its current value is displayed in a tooltip "data tooltips"where it can also be modified if desired.
During coding, the Visual Studio debugger lets certain functions be invoked manually from the Immediate tool window. The parameters to the method are supplied at the Immediate window. Visual Studio includes a host of visual designers to aid in the development of applications.
These tools include:. Visual Studio allows developers to write extensions for Visual Studio to extend its capabilities. These extensions "plug into" Visual Studio and extend its functionality. Extensions come in the form of macrosadd-insand packages.
Macros represent repeatable tasks and actions that developers can record programmatically for saving, replaying, and distributing. Macros, devslopment, cannot implement new commands or create tool windows. They are written using Visual Basic and are not compiled. Add-Ins can be used to implement new functionality and can add new tool windows.
They can create designers and xevelopment tools, as well as integrate other programming languages. However, the managed API isn't as comprehensive as the unmanaged one. Express Editions do not support hosting extensions. On top of that, other packages can be added to customize the installation. The Isolated mode of the shell creates a new AppId where the packages are installed. These are to be started with a different executable. It is aimed for development of custom development environments, either for a specific language or a specific scenario.
It serves as the central location for posting information about extensions to Visual Studio. Community developers as well as commercial developers can upload information about their extensions to Visual Studio. NET through Visual Studio Users of the site can rate and review the extensions to help assess the quality of extensions being posted. An extension is stored in a VSIX file. One of the main advantages of these extensions is that they do not require Administrator rights to be installed.
RSS feeds to notify users on updates to the site and tagging features are also planned. The Community edition was announced on November 12,as a new free version, with similar functionality to Visual Studio Professional.
Prior to this date, the only free editions of Visual Studio were the feature-limited Express variants. Unlike the Express variants, Visual Studio Community supports multiple languages, and provides support for extensions. Individual developers have no restrictions on their use of the Community edition.
The following uses also allow unlimited usage: contributing to Open Source projects, academic research, in a classroom learning environment and for developing and testing device drivers guiee the Windows operating system.
All other use by an organization depends on whether you are classified microsoft sql server 2014 business intelligence development beginners guide pdf free an Enterprise more than freee or more than 1 million USD in annual revenue, per Microsoft. As of Visual Studiothe Professional edition is the entry level commercial edition of Visual Studio.
Previously, a more feature restricted Standard edition was available. Windows Mobile development support was included in Visual Studio Standard, however, with Visual Studioit is only available in Professional and higher editions.
Windows Phone 7 development support was added to all editions in Visual Studio Development for Windows Mobile is no longer supported in Visual Nusiness microsoft sql server 2014 business intelligence development beginners guide pdf free It is superseded by Windows Phone 7. In addition to the features provided by the Professional edition, the Enterprise edition provides a new set of software development, database development, collaboration, devslopment, architecture, testing and reporting tools.
The first version of Visual Studio was Visual Studio Microsoft first released Visual Studio codenamed Boston[] for the city of the same namethus beginning the VS codenames related to places [] inbundling many of its programming tools together for the first time.
