"Data is" or "data are"

[Anglika]

Thanks everyone for the replies.


A few examples are:

[FONT=&quot]The staging begins with coordinated extracts from the operational systems; the raw data is transformed into presentable information in staging area to fit business needs and is finally loaded into the data warehouse in the presentation area.

[/FONT][FONT=&quot]The presentation area is where the data is organized, stored and made available for direct querying by users; report writers and other analytical applications.

[/FONT][FONT=&quot]Data in conventional operational systems is entered either automatically or by a clerk. [/FONT]
​

I am talking about data as a collection of all the information stored in diverse systems.

All of these usages look absolutely fine to me.
