How many mappings can be assigned to a session
-
one
-
two
-
many sessions
-
three
In Informatica, each session can execute only one mapping at a time. This is a fundamental architecture rule - sessions represent a single runtime instance of a mapping. If you need to run multiple mappings, you create multiple sessions or use workflows.
To answer this question, we need to understand the concept of mappings and sessions.
In computer science and programming, a mapping refers to the association or relationship between two sets of elements. In the context of sessions, a session is a period of interaction between a user and a computer system.
Based on this information, the correct answer is:
Option A) one - This option is correct because a session can have only one mapping. During a session, there is typically one-to-one mapping between a user and the computer system, allowing for a single user to interact with the system at a time.
Option B) two - This option is incorrect because a session cannot have multiple mappings. Only one user can be directly associated with a session at a time.
Option C) many sessions - This option is incorrect because it refers to the number of sessions, not the number of mappings per session.
Option D) three - This option is incorrect because a session can have only one mapping.
Therefore, the correct answer is A) one.
