Thus far, the ETL process has taken us through a lot of decision making. Data has had to be cleaned up and handled with care to ensure it is accurate and that it can be worked with. In Chapter 7, we created an SSIS package and set up our data connections. We also configured and t...
Creating SSIS Projects To Develop the ETL process in SSIS, the first step is to create an SSIS project in SQL Server Data Tools (SSDT) where we can create multiple packages and other task related to project. Below graphical representation below shows how to create a new SSIS project. Creatin...
SSIS - 1.简介 软件平台,它包含一个或多个ETL包。 4)ETL包是在服务器上执行的一个用来处理ETL的软件或服务。 5)ETL包是扩展名为dtsx的文件。 6)ETL包可以部署在SQLServer数据库SSISDB上,在SQLServerManagement Studio(SSMS)的IntegrationServices目录下进行管理。 7)ETL包可以在SQLserver上执行,也可以 ...
Instead of using one large computer to store and process the data, Hadoop allows clustering multiple computers to analyze massive datasets in parallel more quickly. It offers four modules: Hadoop Distributed File System (HDFS), Yet Another Resource Negotiator (YARN), MapReduce, and Hadoop Common....

In this lesson, you expand the package you created in Lesson 1 to take advantage of new looping features to extract multiple flat files into a single data flow process. Lesson 3: Add Logging with SSIS In this lesson, you expand the package you created in Lesson 2 to take advantage of ne...

Using an Extract, Load, and Transform (ELT) process uses built-in distributed query processing capabilities and eliminates the resources needed for data transformation before loading. While dedicated SQL pools support many loading methods, including popular SQL Server options such asbcpand theSqlBulkCop...

In the previous chapter, we discussed how to extract data from a source table and transform that data using SQL programming statements. This is a very traditional approach and works well for many professionals, particularly SQL programmers, but can feel cumbersome and tedious to work with....
