课程名称:数据分析师ETL:SQL Server、SSIS、SSAS、PowerBI、Alteryx 课程概述: 本课程旨在探索数据分析领域中的关键工具和技术,专注于ETL(提取、转换、加载)过程,涵盖Power BI、SQL Server、SSIS(SQL Server集成服务)、SSAS(SQL Server分析服务)和Alteryx。 Power BI 是一系列软件服务、应用程序和连接器的集合,能够将各种不相关的数据源转化为一致的、视觉丰富且互动的洞察。无论数据源是Excel电子表格、基于云的数据仓库还是本地的混合数据仓库,Power BI 都能轻松连接并可视化数据。Power BI 包括三个主要部分:Windows 桌面应用程序、在线服务和移动应用程序。 SQL Server 集成服务(SSIS)是一个企业级的数据集成和转换解决方案平台,能够解决复杂的商业问题,用于复制文件、加载数据仓库、清洗和挖掘数据等。SSIS 能够从多种数据源提取和转换数据,并将数据加载到一个或多个目标中,支持无代码的图形化工具以建造解决方案,也可以通过编程方式创建包。 SQL Server 分析服务(SSAS)是一个多维OLAP服务器及分析引擎,旨在对大规模数据进行切片和切块分析,支持多种维度的业务分析。SSAS提供企业级的语义数据模型能力,适用于商业智能(BI)、数据分析和报表应用。 SQL Server 是一个关系型数据库管理系统,允许管理数据库并根据其他应用程序的请求存储和检索数据。它的管理系统部分确保数据库的高效存储以及快速的数据搜索和检索。 Alteryx 是一个能够快速访问、操作、分析和输出数据的软件解决方案,可以用于一系列操作,支持工作流的创建与文档化,适用于各种行业和功能领域的用户。 此课程适合希望增强数据分析技能的学习者,通过实际案例和项目实践,帮助学生掌握数据处理和分析的综合能力。
Power BI is a collection of software services, apps, and connectors that work together to turn your unrelated sources of data into coherent, visually immersive, and interactive insights. Your data may be an Excel spreadsheet, or a collection of cloud-based and on-premises hybrid data warehouses. Power BI lets you easily connect to your data sources, visualize and discover what's important, and share that with anyone or everyone you want.Power BI consists of several elements that all work together, starting with these three basics:A Windows desktop application called Power BI Desktop.An online SaaS (Software as a Service) service called the Power BI service.Power BI mobile apps for Windows, iOS, and Android devices.SQL Server Integration Services is a platform for building enterprise-level data integration and data transformations solutions. Use Integration Services to solve complex business problems by copying or downloading files, loading data warehouses, cleansing and mining data, and managing SQL Server objects and data.Integration Services can extract and transform data from a wide variety of sources such as XML data files, flat files, and relational data sources, and then load the data into one or more destinations.Integration Services includes a rich set of built-in tasks and transformations, graphical tools for building packages, and the Integration Services Catalog database, where you store, run, and manage packages.You can use the graphical Integration Services tools to create solutions without writing a single line of code. You can also program the extensive Integration Services object model to create packages programmatically and code custom tasks and other package objects.SQL Server Analysis services (SSAS) is a multi-dimensional OLAP server as well as an analytics engine that allows you to slice and dice large volumes of data. It is part of Microsoft SQL Server and helps perform analysis using various dimensions. It has 2 variants Multidimensional and Tabular. The SSAS full form is SQL Server Analysis Services.Analysis Services is an analytical data engine (VertiPaq) used in decision support and business analytics. It provides enterprise-grade semantic data model capabilities for business intelligence (BI), data analysis, and reporting applications such as Power BI, Excel, Reporting Services, and other data visualization tools. Analysis Services is available in different platforms.SQL Server is a software application designed to manage databases, it stores and retrieves data as requested by other applications. When software developers are writing new business applications that store information in a database they will very often use SQL Server's functionality to look after the databases rather than reinventing the wheel writing their own code to do the same thing. This makes writing database applications easier and quicker (and therefore cheaper) as well as making them more reliable, scalable and secure.SQL Server is known as a "Relational Database" Management System. Data is stored in tables in a similar way to rows and columns in a spreadsheet. If you imagine a database containing accounting information you may have a table for each invoice with values, VAT, Totals, invoice number etc. Each invoice relates to a customer but instead of recording the customer's details (name, address, discounts etc.) with each invoice you just record it once in a separate table called Customers. The Customers table and Invoices table are linked or "related".The "Management System" part of SQL Server makes sure the databases are stored efficiently and the data can be searched or retrieved as quickly as possible. It also makes sure multiple people connecting to the same data are managed properly so you don't get problems if two people change the same information at the same time.Alteryx is a software solution that allows users to quickly access, manipulate, analyze, and output data. This can be done in a one-off manner or, more commonly, the process (called a "workflow") is something people use on a recurring (daily, weekly, monthly) basis. The way Alteryx builds workflows becomes a form of process documentation allowing users to see, collaborate on, support, and enhance the process. Data can be read and written to files, databases, and APIs. Alteryx is used for access, manipulation, analysis, and output of data. The platform is very robust and can be used in virtually any industry or functional area.
