Is it too expensive to have more than one Information System?

With a business that has an online presence of sales and 50 employees is it too expensive too have more than one Information System.

For my project of an sales and book tracking system, Im asked what info system(s).
I have (DMBS) database management system. (TPS) transaction processing system and (MIS) management information system. Are these all too much?

Thanks

Do all of the systems serve a useful purpose? Then it’s not too many.
