Similarly, Rowset Transformations create and manage rowsets. Split and Join Transformations distribute rows to various outputs, perform lookup operations, copy transformation inputs, and also join inputs into a single output.
Auditing Transformations audit info. Finally, developers can write their own custom transformations. These transformations deserve their own section. The Fuzzy Grouping Transformation cleans data by identifying near-duplicate rows and selecting a canonical row that you can then use for standardization of the data.
This transformation relies on selecting input columns for identification of duplicates and then selecting either fuzzy or exact matches. Exact matching searches only for identical rows with exactly the same values. Fuzzy matching will also include those with near-equal values, based on a similarity score set by the user.
The Fuzzy Lookup Transformation is also involved in data cleansing through standardization, correction of data, and providing missing values. The software uses it to locate near-exact matches of records in a reference table. It is an alternative to the Lookup Transformation, which is only capable of finding perfect matches.
You can use the first as a component of an Integration Services package in order to profile data stored in the server and check data quality. It does this by computing profiles to help the user learn about the data source. It does not work with any third-party source. What is SSIS?

CA ES. SSIS follows the following steps to achieve the integration: It starts with an operational data warehouse, a database designed to integrate data from multiple sources for additional operations on the data. The process of extraction, transformation and loading ETL is carried out. The data warehouse captures data from various sources for useful access and use.
Data is stored in the data warehouse to bring together and manage data from various sources to answer business questions Therefore, it helps in decision making. 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.
