I am a software and database developer currently specializing in Microsoft SQL Server, but I would like to be able to offer Oracle to my customers as well. For SqlServer I use MS SQL Server Developer's Edition on my laptop, which has all of the technical features of SQL Server, but is licensed for development use only and is very low cost (less than $150 ).
I have been taking some of the training for Oracle, but I would like to get something similar for learning, practice, trying stuff out and development on my laptop. Is there anything equivalent available for Oracle developers? I have tried to Google this, but that just keeps turning up "SQL Developer for Oracle" which I *think* is just the developer's GUI and not the DBMS itself.(?)
If it matters, my laptop is running Windows 7 x64. Thanks...
