[Openinteract-help] OI2 and DB Entity Relationships

[Coder <mli...@re...>]

All,

I am having trouble understanding how the OI2 architecture models entity
relationships in code and susequently referes to the at run time.

I have been using Class::DBI for a while now and understand it's mapping quite
well - it's pretty straightforward:

Each entity/object is represented by a table and that object has relationships
(one-to-one, and one-to-many) with other objects.

Each object can tell you what it's children are and each child it's parent when
queried using the correct method.

These are the main functions I am having probelms translating into 'OI2 speak'.

Can anyone shed some light? I have looked through the archives, but have to
admit am a little more confused. The OI2 Tutorial is good, but uses only a one
table, and the Advanced Tutorial does not appear to have been written as yet.

I have seen reference to the fact that Class::DBI could be incorporated, but no
concrete examples of how.

This is the last stumbling block for me before I migrate my apps to OI2, so your
assistance is much appreciated.

Ticha
