Re: Analysing an existing Oracle system

Hi Exodus,

if you have an existing Oracle DB and applications to analyze, you might face a long way to go.
There are Two things to do:

Oracle DB:

    Find out what tables, views, constraints and other schema objects exist in the database.

    You have to analyse the *data model*.    For this purpose, you may use HORA4 from Keeptools, especially its Reverse Engineer function.

   Then You would put this "db structure dump" into a tool like PowerDesigner, to have a map of all tables

   and constraints.
   This is the easyer part of it =)

Applications:

   I personally do not know of any anaylizing tool for this. E.g. You have Oracle Forms & Reports,

   You would have to go through all the Forms and Reports and analyze what they do. They also can call

   each other. And if You are new to Oracle, I assume that You are new to Oracle Forms as well, and

   I am very sorry to say so: You might not be able to make it. I say this because I am working with Forms for

   5 months now, and I had a Oracle background, but I find myself not-knowing-what-to-do many times.

   I cannot give You any advices for other apps than Forms, so maybe other people should answer to it, too.

This is all I can say about it. But please do not feel discouraged, Your job will be definitely interesting !
You will learn quite a lot on it.
