Hi,

I am interested in determining which data management system, VSAM or IMS, currently has a larger market need. Any insight would be much appreciated.

Thanks.

wtam,

IMS (Information Management System ) is a hierarchial database which is entirely different from VSAM (Virtual Storage Access Method) in terms of storage ,retreival and many more concepts.You are trying to compare a database with Access Methodolgy VSAM which also is used to store data but in a complete different way.

Hope this Helps.

There are third party vendors that develop mainframe data solutions, and they usually divided into 3 subsets: CICS VSAM, Batch VSAM, and IMS. My question is more along of the lines of which solution would have a larger market need, VSAM (CICS, batch), or IMS? Thanks

Thanks for the reply. I am a bit confused, as CICS can be used in both IMS and VSAM "environments", so in this case, which would be the more prevalent option?

Thanks
