How many types of transformations are there in SSIS?

How many types of transformations are there in SSIS?

In SSIS-2012 there are nearly 30 types of transformations.

What are SSIS transformations?

The SSIS transformations are the data flow components that are used to perform aggregations, sorting, merging, modifying, joining, data cleansing, and distributing the data. Apart from these, there is an important and powerful transformation in SSIS called Lookup transformation to perform lookup operations.

What are different types of transformations available in data Flow task?

SSIS Data Flow Transformations Aggregate: Like a GROUP BY in T-SQL. Conditional Split: Splits out streams based on one or more conditions. Data Conversion: Allows you to convert columns from one data type to another. Derived Column: Allows you to manipulate existing columns or create new columns using expressions.

What are the different types of containers in SSIS?

There are three types of containers in the Control Flow tab: Sequence, For Loop, and Foreach Loop Containers.

What are asynchronous transformations in SSIS?

Asynchronous transformations do no processes rows independently of each other. This results in the output being processed at another time than the input. Input buffers cannot be reused, as the output can have more or less rows than the input. There are different types of behaviors for asynchronous components.

What is CDC SSIS?

Change Data Capture (CDC) is a feature of SQL Server Enterprise Edition that uses Transaction Log Sequence Numbers (LSNs) to identify insert, update, and delete operations that have occurred within a specified time period. CDC can be implemented in the Enterprise Edition of SQL Server 2008 or later version.

What is difference between Merge and Union all in SSIS?

SSIS Merge Transformation. Merge transformation is very similar to the Union All Transformation, which combines rows from different sources into one output. The main difference is that Union All doesn’t require that the data sources are sorted, nor does its output.

What is aggregate transformation in SSIS?

The Aggregate transformation is used to perform aggregate operations/functions on groups in a dataset. The aggregate functions available are- Count, Count Distinct, Sum, Average, Minimum and Maximum. The Aggregate transformation has one input and one or more outputs. It does not support an error output.

What is conditional split transformation in SSIS?

A Conditional Split Transformation in SSIS is just like the IF condition or CASE statement. It checks the given condition and based on the condition result; the output will send to the appropriate destination path. It has ONE input and MANY outputs.

What are blocking transformations?

Fully Blocking Asynchronous Transformations are the slowest transformations. They require all the data to be pulled from the source(s) before they can be sent to the destination(s).

What is Fuzzy Grouping transformation in SSIS?

The Fuzzy Grouping Transformation in SSIS is used to replace the wrongly typed words with correct words. For example, if 98 people typed the country name as India and two people types as Indi, then SSIS Fuzzy Grouping Transformation will replace the Indi with India.

What is transformation in SSIs?

SSIS Transformations. The SSIS transformations are the data flow components that are used to perform aggregations, sorting, merging, modifying, joining, data cleansing, and distributing the data. Apart from these, there is an important and powerful transformation in SSIS called Lookup transformation to perform lookup operations.

What are the transformation components of integration services 2012?

So, here is the complete list of transformation components built into Integration Services 2012: SSIS Aggregate Transformation. SSIS Audit Transformation. SSIS Cache Transform Transformation. SSIS Character Map Transformation. SSIS Conditional Split Transformation. SSIS Copy Column Transformation. SSIS Data Conversion Transformation.

What are the different types of transformations in SQL Server?

This transformation is classified into the following six types. Character Map Transformation: The Character Map transformation allows you to do character operations on string columns. It makes common string data changes for you. Copy Column Transformation: This transformation is used to add a copy of column to the transformation output.

What is the difference between aggregation and synchronous transformation in SSIs?

In the above example we have applied SUM aggregation but Aggregation transformation provides other options to aggregate data like Count, Count distinct, Average, Minimum and Maximum. Synchronous transformation, allows you to send the data from a single data path to various outputs or paths based on conditions that use the SSIS expressions.
