I have been speculatively asked to write a frontend that will access a mega-large Oracle database. At first it will be read only and a small table may/will be split off for local use, but I think a dial-up connection will eventually be required. I want to use VB5 and ADO. My question/s are;

1.Where can I get a small Oracle db to use locally for testing to come up to speed.
2. Do I have to own a copy of Oracle?
2. Is it difficult to use ?, I am very familiar with Access/VB5  and some ADO etc ?
3. Any good sources of information of how to do this

You will eventually need to purchase a copy of Oracle.  For a short term evaluation, Oracle has several product downloads located here:

http://www.oracle.com/products/trial/html/trial.htm

Here is a good starting point for ADO:

http://www.microsoft.com/sql/library/adosql.exe

It is geared for MS SQL Server, but has generic sample code that will work with Oracle.

When I said, do I have to own a copy of Oracle I meant in the sense that I can program for Access in VB5 and ADO without owning MS Access. My impression is that Oracle is a very expensive DB. From experience of many years ago Oracle was a pig to use. Hopefully things have changed.

Sorry to say, but you can't treat Oracle like you would Access.

You are right, Oracle is expensive and can be difficult to administrate and tune.  I have not used the NT product as yet, perhaps it is a little more friendly.

To get a feel ADO programming, you can use Access as an ADO/ODBC provider.  It is terribly inefficient, but it gives you the concepts without the expense...
