Informatica Data Warehousing Interview Question:

What is the difference between constraind base load ordering and target load plan?

Submitted by: Administrator

Constraint based load ordering

example:

Table 1---Master

Tabke 2---Detail

If the data in table1 is dependent on the data in table2 then table2 should be loaded first.In such cases to control the load order of the tables we need some conditional loading which is nothing but constraint based load

In Informatica this feature is implemented by just one check box at the session level.


A CBl specifies the order in which data loads into the targets based on key constraints

A target load plan defines the order in which data being extracted from the source qualifier
