Overview

A DID is organized in several layers of information. The ITP/SDK for iSeries follows this organization closely.

From every layer down a 1:n relation is possible: a DID can have 1 or more DID-sources linked to it, A DID-source may contain one or more Entries or User defined functions. A DID and a DID-source are the only items that may exist in the ITP/SDK for iSeries without relation to another SDK-item, but they will then only serve as intermediate results of the DID development process. Entries, Entry-Subentry relations and User-defined functions can only exist inside a DID-source, Formal parameters and Fields can only exist within an Entry.
