Can we generate surrogate keys in informatica without sequence generator?

To solve this question, the user needs to know about surrogate keys and how they can be generated in Informatica.

Surrogate keys are system-generated keys used as primary keys in a database. These keys have no business meaning and are used to uniquely identify each record in a table.

Now, let's go through each option and explain why it is right or wrong:

A. Yes: This option is correct. Surrogate keys can be generated in Informatica using various methods other than the sequence generator transformation. For example, we can use the Rank or Expression transformations to generate surrogate keys.

B. No: This option is incorrect as it is possible to generate surrogate keys in Informatica using other transformations besides the sequence generator.

C. May be: This option is incorrect since generating surrogate keys without sequence generator in Informatica is possible, it is not a case of "may be."

D. Surrogate keys cannot be generated in informatica: This option is incorrect. Informatica provides several options to generate surrogate keys, and sequence generator is just one of them.

The Answer is: A
