I am using Oracle 9i on a specific application that was designed back in 2000 -- no supporting documentation, very little training and I'm new to Oracle and sql.
I'm currently using Toad for Oracle which allows me to create query templates. Toad for Oracle has existing sql templates which I can modfiy so I'm running queries and in some cases using user_constraints and user_cons_columns to gain some knowledge of this application.
I can apply the queries and gain the information that I need. but I'm not learning or understanding "Data Dictionary" so I'm looking for someone that could possibly give me a laymans definition and possibly suggest queries and/or or statements that could be useful for my specific situation.
Life's tough enough and I really do believe without obtaining an understanding of Oracle I won't have the skills to tackle this challenge.
Thanking you in advance for your support and sharing your knowledge.
