Hi,
I am new to Oracle and have a few questions. I currently work with an existing Oracle DB. But the database is a mess in terms of data and forms. Currently, the database is being used for very basic purpose; storing customer information. I want to restructure the database and import the data back into the improved Oracle. Is it possible to dump all the data into a temporary storage such as an excel spreadsheet and then restructure the database. And then be able to import the old data back into Oracle. I know that you can export tables from Access to Oracle but I want to 'clean' up the existing Oracle DB and its data.
Any suggestions on how to do this??

Getting all the data into an Excel spreadsheet is probably possible but won't be straightforward, and is not recommended as a backup strategy. Oracle provide the Export and Import utilities (among others) for dumping data out to file.
It might be simplest to leave the data in place and create a second schema (account + tables) with an improved design. Then you can migrate the data across using SQL e.g. INSERT INTO newtablename SELECT columns FROM oldaccount.tablename.
