Describe an XML Configuration file package configuration:

Stores configuration settings in an XML file in the file system. You can store multiple configurations in an XML file.
|
|
|
Describe an Environmental Variable package configuration:
|
Saves the configuration information inside the system's global variables collection, which is called an environmental variable. When you add an environmental variable configuration, you can choose only one property for each environmental variable configuration.
|
|
|
Describe a Registry Entry package configuration:

Describe a parent package variable configuration type:
|
provides a way to inheit the value of a variable from a parent package. When a package is executed from another SSIS package by using the Execute Package Task, the values of its variables are available to the child package through the Parent Package Variable configuration. With this configuraiton type, you can choose only one package property setting at a time.

|
Why would you use an expression in a variable expression?
|
Variable can be dynamically set through an SSIS expression. This is done when a variable is selected in the Variables window and the properties window is open. To use this capability, you need to se the EvaluateAsExpression property to true and then enter an expression in the expression property
|
|
|
Why would you use an expression in a property expression?
|
Property expressions are a way that SSIS can dynamically update the valudee of properties while a package is running. Instead of using a hard-coded value for a property, you can use an expression to generate a value.

|
Unlike configuration entries that are read at the start of the package execution, property expressions are updated when the property is accessed by the package during package execution so it can change during package execution.
|
|
|
