Standard datatypes of Informatica

Question

I read somewhere, but i got confused. They asked, Datatypes of informatica. Informatica is tool, not a programming language. So, How informatica has own datatypes. Still if it is available then please let me know.

Also tell me, what are the informatica datatypes?

Answer 1

A datatype is not a concept exclusive to programming languages. Excel is a tool and yet you can set a cell's datatype (called category in Excel) to Number, Date, Percentage and a few others.

Different transformations support different datatypes, but here's a list for an expression:

• bigint
• binary
• date/time
• decimal
• double
• integer
• nstring
• ntext
• real
• small integer
• string
• text

Answer 2

Informatica has its own set of datatypes, because it is useful to converting any source datatypes (database/files)into Informatica compatible datatypes for further processing.

Whenever you drag any source definition in a mapping it automatically creates a source qualifier which converts source datatypes into suitable Informatica datatypes.

Answer 3

In informatica various data types are supported ( depending on transformation and clients requirements) . Below are the most usable data types :

1. bigint
2. small integer
3. date/time
4. date
5. decimal
6. double
7. integer
8. nstring
9. string
