课程名称：数据分析师 - ETL/SSIS/SQL/PowerBI 课程概述： 数据分析师在各个行业（如金融、咨询、制造、制药、政府和教育）中需求旺盛。数据分析师需要具备良好的细节关注能力、沟通能力和高度组织化的能力。他们不仅要理解数据，还需要通过清晰的可视化、书面和口头沟通提供见解和分析。 常见的组织问题是如何从多个来源收集数据，利用多种格式将其转移至一个或多个数据存储。目标数据存储的类型可能与源数据存储不同，格式也常常不同，或者数据需要在加载到最终目的地之前进行格式化或清理。 提取、转换和加载（ETL）是用于从多个源收集数据的管道，它根据业务规则转换数据，并将其加载到目标数据存储中。SQL Server 集成服务（SSIS）是一种强大的商业智能工具，最适合与 SQL Server 数据库协作。安装 SQL Server 数据工具（SSDT）时，会将其添加到 SQL Server 数据库中，为 Visual Studio 提供商业智能模板，以便创建集成项目。 SSIS 的应用包括： - 数据集成 - 数据转换 - 解决复杂的商业问题 - 更新数据仓库 - 清理数据 - 数据挖掘 - 管理 SQL Server 对象和数据 - 从各种数据源提取数据 - 将数据加载到一个或多个目的地 SQL 是访问和操作数据库的标准语言，能够执行的操作包括： - 查询数据库 - 从数据库中检索数据 - 向数据库插入记录 - 更新数据库中的记录 - 从数据库中删除记录 - 创建新数据库 - 在数据库中创建新表 - 创建存储过程 - 创建视图 - 设置表、过程和视图的权限 Power BI 是一种商业分析解决方案，可视化数据并在组织内共享见解，或将其嵌入到应用或网站中。通过连接数百个数据源，利用实时仪表盘和报告生动呈现数据。您将学习如何快速分析数据并使用 Power BI，这一强大的商业分析工具集包括 Power BI 服务、Power BI Desktop 和 Power BI Mobile，能够更有效地创建和共享对他人有影响力的可视化。 在本课程中，您将学习如何开始使用这一强大的工具集，涉及连接和转换基于 Web 的数据源的主题，并学习如何在 Power BI 服务上发布和分享您的报告和可视化。
Data analysts are in high demand across all sectors, such as finance, consulting, manufacturing, pharmaceuticals, government and education.The ability to pay attention to detail, communicate well and be highly organised are essential skills for data analysts. They not only need to understand the data, but be able to provide insight and analysis through clear visual, written and verbal communication.A common problem that organizations face is how to gathering data from multiple sources, in multiple formats, and move it to one or more data stores. The destination may not be the same type of data store as the source, and often the format is different, or the data needs to be shaped or cleaned before loading it into its final destination.Extract, transform, and load (ETL) is a data pipeline used to collect data from various sources, transform the data according to business rules, and load it into a destination data store. SQL Server Integration Services (SSIS) is a useful and powerful Business Intelligence Tool. It is best suited to work with SQL Server Database. It is added to SQL Server Database when you install SQL Server Data Tools (SSDT)which adds the Business Intelligence Templates to Visual studio that is used to create Integration projects.SSIS can be used for: Data Integration Data Transformation Providing solutions to complex Business problems Updating data warehouses Cleaning data Mining data Managing SQL Server objects and data Extracting data from a variety of sources Loading data into one or several destinationsSQL is a standard language for accessing and manipulating databases.SQL stands for Structured Query LanguageWhat Can SQL do?SQL can execute queries against a databaseSQL can retrieve data from a databaseSQL can insert records in a databaseSQL can update records in a databaseSQL can delete records from a databaseSQL can create new databasesSQL can create new tables in a databaseSQL can create stored procedures in a databaseSQL can create views in a databaseSQL can set permissions on tables, procedures, and viewsPower BI is a business analytics solution that lets you visualize your data and share insights across your organization, or embed them in your app or website.
