I connect to oracle database using toad and in the schema browser , i see the schema and all the tables in the schema. Now I want to generate teh erd diagram and have it printed out in a big paper (not the a4 size) . How do i go about doing this . I can understand better if i see all th tables and their relationships (with all those lines) connecting the tables.....

I am not sure if TOAD is capable of that.  I do not use TOAD at all.

I believe that Visio is capable of that.  Probably not the best tool, but it will work.  For reverse engineering diagrams, I have found it does a pretty good job.  I would not use it for forward engineering, but I do use it quite often to reverse engineer a diagram from existing tables.

I agree, you have to use a tool that is designed to do ERD diagrams, and TOAD is not designed to do that.  There are a number of tools that can do ERD diagrams.  Do you have one of them?
I don't have toad in here, so i can't check this, but i think it can generate an erd diagram.

ARE THERE ANY free tools available..

I'm using TOAD for Oracle Professional V8.5 and it does have the facilty for creating ER diagrams.
I can email details about is features to you if you like.  I'm not sure if this is available in the basic TOAD for Oracle package and the professional version does cost a good bit more (but is worth it).  List price is about £3000 which  gives you a license for up to 4 users.  There is also a module called QDESIGNER which Quest (the TOAD people) have also produced.  Check out this link for info about this and their other products.
You can email me at my published email address under my EE account to request more TOAD info.
