Best Database selection for Client/Server Application (Multiuser) with Delphi?

Question

i want to code a software with Delphi XE, that will be able to connect to a server and users should be able to read/write the database.
All records will be string (unicode enabled), maybe small amount of it can be blob.

My needs are;

• Multiple users enabled
• More than one user should be able add new records at one time
• Capable of storing huge amount of data
• Users can be able to edit their own records
• Unicode enabled
• As possible as low cost solution

Thanks right now...

Answer 1

I vote for Firebird. It fits all your needs and it is free.

Answer 2

I would go with postgres - it's also free and is very fast.
