SSIS Tutorial

The SQL Server Integration Services, SSIS, is a powerful ETL tool. Although it is the most powerful tool, you can quickly learn SSIS tutorials in 28 days (Maximum). Remember, it is the second-largest tool for performing Extraction, Transformation, and Load (ETL process) operations.

What is SSIS?

Firstly, The SSIS ETL tool Extracts data from different sources and transforms that data according to user requirements. And then loads data into various destinations. This SSIS tutorial covers all the topics on Connection Managers, Data Sources, Transformations, Control Flow, and Data flow tasks.

Secondly, this SSIS ETL tool helps build enterprise-level data transformation and data integration solutions. It is beneficial in loading data from regular transactional data into Data Warehouse. So you can create reports using the transformed data with the help of SSRS, Tableau, etc.

Apart from the Data Warehouse application, you can also use SQL Server Integration Services to work on typical data integration applications. Before learning the SSIS tutorial, I suggest learning SQL Server basics, at least SELECT Statements.

What is SSIS used for?

To work with the SSIS packages tutorial, you need a development environment and a Management studio. And the Microsoft SQL Server provides two options to develop the SSIS package, first using BIDS or SSDT. But the second option is Import and Export wizard.

You can use the second option to perform the basic data loading because it does not need a different environment. As a result, SSIS uses the wizard to select all the sources, transformations, and destinations.

Remember, you also need one more item called SQL Management studio. It helps to monitor and manage the developed SSIS packages in a production environment.

SSIS Integration Service Includes the following

  • A graphical user interface to develop packages without writing any code.
  • SSIS has many transformations and control flow tasks to clean or transform data.
  • It has a Catalog database that we configure at the beginning to deploy packages, run, and manage them from SSMS. The Integration Services relies on SQL Server Agent for scheduling the operations.

SSIS Tutorial Introduction

The Microsoft SQL Server Integration Services included many built-in tasks and transformations. Use them to solve complex business problems by building high-performance data integration packages. One can use this SSIS tutorial to update warehouses, data mining, and download or copying files. Next, extract and transfer data from XML to SQL, etc.

To develop or create an integration package, you need Data Tools or BIDS. Therefore, I suggest you install the SQL Server Data Tools, Visual Studio, or Business Intelligence Development Studio (BIDS) to practice this SSIS tutorial.

  1. Install Data Tools or BIDS
  2. Create a New Integration Services Project
  3. Create a New Package

SSIS Tutorial on Data Flow task

There are three types of SSIS SQL Server Integration Services data flow components: Sources, Transformations, and Destinations. Each data flow component has an output. Use the result to connect with other members. For instance, connect the source output to transformations and then connect the transformation output to the destination.

While working with the SSIS tutorial on data flow components, you always have to check the column mappings. And this is a place where you might end up with errors. I mean wrong column mapping or no column mapping, etc.

NOTE: I suggest you download Adventure Works, and Adventure works DW databases to practice these SSIS tutorial examples. Because we use these two databases in this entire section. Please refer to Install Adventure Work and SELECT Statements in Server.

SSIS Tutorial on Connection Managers

This SQL SSIS tutorial extracts data from different sources, transforms it and loads it to a completely different destination. Firstly, we need a connection manager to establish the connection between the package and source and package and destination.

In addition, the SSIS connection manager contains the physical connection string properties to create or establish a connection at a run time. In SSIS Integration Services, there are two types of connection managers. And they are Package Level (designed in a 5th window) and Project Level (created in the Solution Explorer window).

The project level connection managers shared among all the packages in that project. It is available at the project deployment. This section of tutorial covers establishing connections between this SQL SSIS and different data sources.

Learn everything about SSIS Connection Managers tutorial in the First two days. Generally, it takes one day to cover this topic. Most of the steps in those links are the same. I think the maximum 2 to 3 steps may differ.

  1. Project and Package Connection Managers
  2. OLE DB Connection Manager
  3. ADO Connection Manager
  4. ADO.NET Connection Manager
  5. Cache Connection Manager
  6. EXCEL Connection Manager
  7. File Connection Manager
  8. FTP Connection Manager
  9. SMO Connection Manager

SSIS Tutorial on Sources

The next two days concentrate on learning SSIS tutorial on Sources and destinations. As I said before if you know the connection managers, you are good with Destinations and Sources.

The main motive of the integration package is to transfer data from various sources to a destination. It means you need a Source to get the data from and a Destination to load into it. The following tutorial is the list of common sources used in the SSIS package development.

  1. Source Asst.
  2. ADO.NET Source
  3. Excel Source
  4. OLE DB Source
  5. Flat File Source

Destinations

The Sources and Destinations article has all the information about the available sources, destinations, and how to export or import data from SQL to Excel or Text and vice versa.

  1. ADO.NET Destination
  2. OLE DB Destination
  3. FLAT FILE Destination
  4. System Variables

SSIS tutorial on Transformations

The SQL SSIS Integration Service is all about Sources, Transformations, and Destinations. You need Connection Managers to connect with sources and destinations. So, if you know the connection Manager, then you do not have to think about the Sources and Destinations.

Spend the next ten days is all about transformations. I don’t think you need 10 days to complete the transformations. In all the SSIS tutorial examples, we explained each transformation along with the Source and Destination. However, you can skip those steps.

The Transformations modify or clean the data, perform data conversions, perform data aggregations, etc. The following SSIS tutorial shows the list of available transformations. Please click on the link to see the definition and a practical example of each transformation.

SSIS Tutorial on Control Flow Tasks

Every Integration Services package consists of a control flow tab. You can optionally use the SSIS control flow tasks within this control flow tab, one or more data flow tasks. Perhaps you can use the combination of both the control flow task and data flow tasks.

It is where we design the complete data flow. Furthermore, it is the place where we perform all the SSIS transformations.

Deploying the SQL SSIS Integration Services project is where we should decide the package execution time and the authorized user to perform the same. There are different ways that you can deploy your packages. It starts using BIDS/SQL data tools, Import and Export Data wizard, and Management Studio.

Therefore, you can use either of these options to deploy packages to Server. This SSIS tutorial catalog section covers the essential topics beneficial for the production environment.

What is the SSIS Package Work environment?

It is a business intelligence tool that provides data transformation solutions for various organizations. The tutorial screenshot below shows the SSIS work environment and how it is used to create SQL Integration Services projects and learn.

SSIS Tutorial

From the above SSIS tutorial screenshot, we had divided the window into different parts

  1. Solution Explorer: It is a combination of project level connection managers, actual packages, and project parameters.
  2. Properties: Use this window to change the properties of every task.
  3. Toolbox: It provides a lot of built-in tasks, containers, transformations, sources, destinations, and administrative tasks to solve complex business problems. Use these graphical tools by dragging and dropping those tasks in the work environment. It means we do not have to write a single line of code to perform most of the operations.
  4. Information: Shows the information about SSIS toolbox items and this tutorial covered all of them.
  5. Connection Managers: Use this window to create a package level connection managers
  6. Package Designer window.

What is Project Development Model?

The SSIS project combines Connections Managers, Packages, and project parameters (optional). Furthermore, the SQL Server Integration Services is an ETL (Extract, Transform, and Load) tool. That means you can follow this SSIS tutorial to extract data from various sources such as Excel Files, Flat Files, XML Files, and Relational databases. Furthermore, transform (slice and dice) them according to your requirements and load the data into the destination.

SSIS Advantages

You can also deploy packages to the cloud platform Azura. And also, you can schedule the deployment of the package to Azura.

We have to deploy the whole project to add one additional SSIS package, but it is not the case with the Integration services tutorial. Instead, it allows you to add one or more packages to the existing project, called incremental package deployment.

You can restrict the SSIS Integration Services access to specific users. And. Therefore, the administrator has to run the DCOM configuration tool to grant permission.

The SSIS catalog database has an option to add the Always On Availability groups option. So, whenever a database failover happens, one of the secondary nodes becomes the primary node automatically.

SSIS supports the Always Encrypted feature. Therefore, it allows you to load data to encrypted database columns.

By redirecting the wrong data to an error output, you can see what columns are throwing errors, find erroneous data, and effectively diagnose the issue.

Important SSIS Components

Although there are many built-in components in the Integration Services, there are some situations where we need a custom task to perform some business-centric operations. There are two most powerful SSIS components to fulfill this: Script Task and Script Component. 

  • If you want the custom control flow task, use SSIS Script Task along with C# or VB that we mentioned in this tutorial and write your functions.
  • Use the script component as the Source, Destination, or Transformation for the custom data flow task.

You can also create, run, and deploy a package without opening the interface. For instance, with the .Net application, you can create a package. Next, perform some operations, and deploy them to the catalog.

Disadvantages of SSIS

In order to configure the SSIS event logging, you have to edit the registry keys, and we convert them in this tutorial.

Upgrading the SQL Server instance will not automatically upgrade the package to the current release. You have to do it on your own manually. When it comes to SSIS script components, you have to update the assembly versions referenced by the members manually.
