What is parameter map?
Parameter maps are objects that store key-value pairs. Each parameter map has two columns, one for the key and one for the value that the key represents. You can manually enter the keys and values, import them from a file, or base them on existing query items in the model. You can also export parameter maps to a file.

What is the difference between mapping parameter and mapping variable?
Unlike a mapping parameter, a mapping variable represents a value that can change through the session. The Integration Service saves the value of a mapping variable to the repository at the end of each successful session run and uses that value the next time you run the session.
What is a determinant key?
A primary key or any candidate key is also a determinant while the opposite is not true. A determinant can uniquely determine one or more attributes in the row. A candidate key can uniquely determine the entire row.
What is a determinant ERD?
A determinant can define the set of database columns (query items) that uniquely identify a set of data or it can identify a set of columns that identify a non-unique set within the data.
What is the difference between mapping variables and mapping parameters?
What is the primary purpose of using mapping parameters and variables?
Purpose. A mapping can utilize parameters and variables to store information during the execution. Each parameter and variable is defined with a specific data type and their main purpose is to provide increased development flexibility.
What are parameterized reports?
A parameterized report is a dynamic report based on input from the application user or another component in the application. The application user enters search criteria which is used to generate the report. For example, the user may want to see all issues assigned to a particular person.

How do I create conditional query subjects for parameter maps?
Use parameters to create conditional query subjects that allow for substitutions when the report is run. Parameter maps are objects that store key-value pairs. Parameter maps are similar to data source look-up tables. Each parameter map has two columns, one for the key and one for the value that the key represents.
What is a parameterized filter in Cognos?
