What is mean by Parameters? Explain different types of Parameters available in SSIS?

 

SSIS Project & Package Parameters

Project parameters are new with SSIS 2012.  A project parameter can be shared among all of the packages in an SSIS project.  You want to use a project parameter when, at run-time, the value is the same for all packages.

Package parameters are also new with SSIS 2012.  A package parameter is exactly the same as a project parameter – except that the scope of a package parameter is the individual package it resides in.  You want to use a package parameter when, at run-time, the value is different for each package. 

SSIS Package Parameters

Note that project parameters do *not* have an expressions property to define their value.  They are intended to hold a literal value which does not change while the package executes.

See in the image at the top of the page that project parameters can pass a value to variables?  Parameters can also pass values to all kinds of objects in SSIS – basically any property that allows an expression.

You can think of parameters are the replacement for package configurations which were used in earlier versions of SSIS.

Difference between ETL vs. ELT

Image
  Difference between ETL vs. ELT Basics ETL ELT Process Data is transferred to the ETL server and moved back to DB. High network bandwidth required. Data remains in the DB except for cross Database loads (e.g. source to object). Transformation Transformations are performed in ETL Server. Transformations are performed (in the source or) in the target. Code Usage Typically used for Source to target transfer Compute-intensive Transformations Small amount of data Typically used for High amounts of data Time-Maintenance It needs highs maintenance as you need to select data to load and transform. Low maintenance as data is always available. Calculations Overwrites existing column or Need to append the dataset and push to the target platform. Easily add the calculated column to the existing table. Analysis

What are the for each loop enumerators available in SSIS?

  Below are the lists of various types of enumerators provided by SSIS Foreach Loop Container: Foreach  File Enumerator : It enumerates files in a folder. The plus point here is it can traverse through subfolders also. Foreach  Item Enumerator : It enumerates items in a collection. Like enumerating rows and columns in an Excel sheet. Foreach  ADO Enumerator : Useful for enumerating rows in tables. Foreach  ADO.NET Schema  Rowset  Enumerator : To enumerate through schema information about a data source. For example, to get list of tables in a database. Foreach   From  Variable Enumerator : Used to enumerate through the object contained in a variable. (if the object is enumerable) Foreach   NodeList  Enumerator : Used to enumerate the result set of an XML Path Language (XPath) expression. Foreach  SMO Enumerator : It enumerates through SQL Server Management Objects (SMO) objects.

What are the SSIS package protection levels?

  There are 6 different types of protection levels. Do not save sensitive – (When exporting using DTUTIL specify for protection- 0) Encrypt sensitive with user key – 1 Encrypt sensitive with password – 2 Encrypt all with password -3 Encrypt all with user key – 4 Rely on server storage Do not save sensitive:  makes the sensitive data unavailable to other users. If a different user opens the package, the sensitive information is replaced with blanks and the user must provide the sensitive information. Encrypt sensitive with user key:  Uses a key that is based on the current user profile to encrypt only the values of sensitive properties in the package. Only the same user who uses the same profile can load the package. If a different user opens the package, the sensitive information is replaced with blanks and the current user must provide new values for the sensitive data. If the user attempts to execute the package, package execution fails. Encrypt sensitive with password:...
