Hi Nathan

I suspect that if the i is not acting as a database server, then it
probably is not doing anything at all.

I didn't mean to give that impression.

I wonder if you really meant a database that is exposed via web services
instead of ODBC and the like.

Kind of. ODBC and similar interfaces expose all the attributes of a
database - the names and layouts of all database objects and other database
metadata, in addition to the values of rows and columns. Under ODBC and
similar interfaces, there is a tendency to implement business logic in the
application, as opposed to implementing business logic in the database
layer.

I don't see web service APIs exposing as much data, and probably would NOT
expose database metadata. With web services, there is more of an emphasis
on exposing "functionality", such as the implementation of data validation,
business rules, referential integrity constraints, applications specific
error handling, and such.

Personally, I don't see this as happening as the tooling to create web
services on the i is (mostly) pretty primitive compared to other systems
which have the advantage of frameworks where web services can be created
and exposed at scale.

Whatever there may be lacking, that could change. Right?

it appears you have built programming infrastructure to do this but this is
something of an exception.

I have some infrastructure. But my framework is geared more toward native
IBM i web applications. Web services have some of the same requirements,
and other requirements that are specific to "services".
