Re: Oracle in system i termonology -- MIDRANGE-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Index = keyed logical
View = unkeyed logical with dropped fields, substringed fields, ect..
plus lots more you can do in an DDS logical.

One thing to understand, with RPG and record level access, you
explicitly open and use a keyed logical.

Whereas with SQL, on either the i or Oracle, you use the physical
table (PF) or view and behind the scenes the query engine may or may
not use the index.

HI I was wondering if there is someone in the group who knows both system i and Oracle and could then explain the basiscs to me in system i terms of the Oracle setup. I am not sure for example what is meant by indices or is this like a Logical file.

TIA,Adam
