Database Compare

I look like to know a little bit more about two databases.  Paradox and Interbase.
I want to know if those database are relational ones?
What exactly relational database mean?
Are they made for multi-user environment?
How do they compare to other database such as SQL server, Oracle, Sybase etc.

Thanks

Paradox is the baby relational database from Borland, and Interbase is their major relational database.  Strictly speaking, a relational database follows E. F. Codd's rules (partially) for database design.  Thes include, among other items (and no database follows all his rules), each row having a unique key, normalization of data, use of foreign keys to establish relations, and enforcement of relational integrity by the database engine.

Now, both Paradox and Interbase can be used in a multiuser environment, but interbase is designed to be an enterprise level database, whereas Paradox will not "scale up" to handling the number of users, size of tables and activity levels for access and update frequencies needed for company and enterprise level databases.

Paradox is comparable to DBase, Foxpro, MS Access, and Clipper databases (although it has stronger referential integrity enforcement than those other systems), while Interbase is comparable to SQL Server, Oracle, Informix, etc.

Making a useable multiuser system is much more than just your choice of database servers.  A great deal of the capability is dependent on your data design, and your application development.
