I've no idea what the context was, but I think there are probably two ways I would expand the statement:

(a) Data lasts longer than programs and has more value. Therefore don't lock your data into proprietary formats that won't survive the software used to create them.

(b) In designing a software system, the core piece of design that you need to get right is the data model.
