Here’s i compare two technologies ( Not Technically but just about what i feel ) and this is just my opinion and others might well disagree with me too . Here we go .
Anders Hejlsberg was involved in C# and for Delphi too and this puts me in a quetion on there might be similarities too …

BDE and NVARCHAR . Should i go for ADO or dbExpress ?
Last week , i was working on a task that basically supports the use of SQL Server 2005 instead of Oracle .
The following Interesting observations were made during this time .
The Project used a lot of BDE components ( TQuery , TDatabase , TTable ) , which connects to the Oracle through the driver Oracle Driver that comes with the Delphi 7.
Degisy Data Suite for Delphi 7
Degisy Data Suite is a package of Visual Component Library ( VCL ) components for accessing the Paradox and DBASE Database .
