Hi

I don't think so there exists any highlighting point to differentiate IMS vs DB2.

As a database IMS met 4 main data-related goals
* Increase data independence.
* Maintain data integrity.
* Reduce data redundancy.
* Increase data security.

DB2 too covers the above goal.

If there exists any additional information please add on.

Probably it will be the non-portability of IMS applications.
If the application is in DB2 we can use ODBC/CLI(call level interface)
to migrate it to any plat form.Only thing is it should be compiled and link edited with those API's. I don't think IMS is not good in that regard.

Another point is the flexibility of the data types DB2 provides. We can store Large Objects(LOB), Graphics etc which i believe not possible in IMS.

More over in the new generation computing the concept of federated database is upcoming, to which DB2 can stick, but IMS can't.

Wanna know more about federated DB?
