SSIS ETL

A few years back, organizations discovered the power of analytics for their business, customer, marketing, sales, and operations data. They understood that the data that they generated on a daily basis was a gold mine in terms of making data-driven business decisions, building amazing products, and understanding their customers better.

Since then, the industry of analysis observed a boom and every organization wanted to analyze its data and make the best use of it. They derived insights from the data and increased their efficiency by making the right decisions.

Handling such a huge amount of data comes with a con. There is a good possibility the data might be lost or misused. It is hard to maintain data integrity and optimizing storage for an exponentially increasing data load is a challenging task. So to tackle this, organizations analyze relevant data and store the analyzed data elsewhere (some of the data may have a one-time use). So as a result a lot of movement of data is involved and this is where ETL tools come into the picture.

In this article, we will briefly discuss ETL and its advantages. Then you will learn about Microsoft SSIS ETL and how you can set up your ETL Pipeline with Microsoft SSIS.

Before talking about how to set up an SSIS ETL, you need to understand what an ETL tool does. ETL stands for Extract, Transform, Load. ETL is the process of extracting data from a source, transforming it, and loading it into a destination. It can simply be termed as moving data from one place to another. Sometimes moving data is easy. For example, moving data from one text file to a csv file. 

Consider moving data from one database to another or from a Customer Relationship Management software to a Data Warehouse. Now, that is a challenging task to achieve and it requires a lot of configuration and effort. So ETL tools generally assist in moving data from various sources to destinations that are hard to integrate.

Learn in-depth information about ETL in the following guide – Ultimate ETL Guide: 14 Comprehensive Aspects.

Organizations are generating useful data on a daily basis that goes to waste if not utilized properly, hence they leverage ETL tools to move data to a central Data Warehouse where they can analyze it and make important business decisions.  

There are a number of ETL tools you can choose from. Some of them are Hevo Data, Stitch, Fivetran, Microsoft SSIS, Talend, etc. Each tool offers its own unique features. Depending on your business requirement you can choose an ETL software that works best for you. Here, you will learn about SSIS ETL.

History of SSIS

Data Transformation Services was replaced by SSIS when after the first release of Microsoft Server 2005. Earlier DTS was included in all the versions but SSIS is available for selective editions. Then the next release was SQL Server 2008 that came with new sources and updates.

SQL Server 2012 was a major release for SSIS as it came up with the new concept of a project deployment model that allows users to deploy the entire project on the server unlike individual packages as before. SQL Server 2014 and 2016 didn’t come up with any major updates in the SSIS except for some additional sources.

Most Important Features of SSIS

SSIS comes with a plethora of features that help users manage data. A few features of SSIS are listed below:

1) Built-in Data Connectors

With the release of the new version of SSIS, it supports many built-in connectors that allow users to establish connections with data sources using connection managers. 

It supports Text, XML, Excel sheets, Relational Databases that have reference data, and Analysis Service Databases. SSIS can connect to WMI (Windows Management Instrumentation), SMO (SQL Server Management Objects), messaging queues, and mail servers. SQL Servers are used for transfer tasks and temporary work tables.

2) Transformations and Functions

SSIS offers many transformations and functions that are built-in, and developing software is easier to use. It comes with various types of transformation that include BI (Business Intelligence) Transformations, Row Transformations, Split and Join Transformations, Rowset Transformations, Auditing Transformations, and Custom Transformations.

Each transformation also provides different kinds of transformations for cleaning and mining data, creating and updating columns, etc. Split and Join transformations can distribute rows in various outputs.

3) Fuzzy Grouping and Lookup Transformation

Users can use Fuzzy Grouping to clean data by detecting near-duplicate data and canonical rows to standardize the data. The Fuzzy Transformation looks for near value based on the score value provided by the user. 

The Fuzzy Lookup Transformation performs data cleaning activity by standardizing it, correcting the data, and filling the missing values. The SSIS uses Fuzzy Lookup Transformation to locate the similar near values in a reference table.

4) Data Profiling Tools

The Data Profiling Tools that SSIS offers are the Data Profiling task and Data Profile Viewer. The Data Profiling task is used to profile data in the server and perform data quality checks. All this process is accomplished by computing profiles so that users can learn more about the data source.

The Data Profiling Viewer allows users to review the Data Profiling task and it supports drill-down capabilities that help users understand data quality.

Prerequisites

You need to make sure that you have the below software installed and set up before creating an SSIS ETL:

  • Microsoft SQL server

When you reach this step your data is in a transformed format compatible with the destination. To configure the OLE DB destination go to the SSIS Toolbox. In the toolbox expand Other Destinations and drag the OLE DB Destination onto the design surface below the lookup transformation.

Connect all the components together on the design surface to define the flow. Navigate to the Input Output Selection dialog box. In the Output list box, select Lookup Match Output, and then click on the OK button. Rename your destination component. Now double-click on the component and configure the destination in the Editor dialog box. Now click on the Ok button.
