Firebird SQL and Web Traffic Analysis with Delphi
Whether you want to learn how to efficiently import data into Firebird, or you wonder if it is worth upgrading to Delphi 2010 for “routine” tasks, this article will give you some food for thought.
In particular, this article explores the use of Delphi and the open-source relational database system named “Firebird SQL” to load and analyze web traffic logs. Along the way, the size and performance of EXEs compiled with Delphi 7 versus Delphi 2010 are compared, plus the speed of Firebird 1.5 versus Firebird 2.1 and four common Firebird data access components are measured.

Database recovery is done in four steps. Here’s how you do it:
#RIP #Dudley #GDML in Firebird 3.0 – #Sql won
Dudley – Sounds like DDL (data definition language) and is the pre (interbase) 4.0 data definition utility GDEF. It’s actually named after Dudley Doright, a character from Rocky and Bullwinkle. GDEF accepts a data definition language based on GDML.

Another definition on original source code description (interbase 6.0)
DDL utility. Interpreted commands in the old data definition language (declare relation, declare field – square brackets where you want to put parentheses). Generates BLR for views and triggers, GDML (non-SQL relational language) for metadata updates.
Switch between versions of Firebird SQL Server
Pierre Yager posted in his blog an interesting Windows script (aka. bat file) to easily switch between different versions of the Firebird server. Check it out.
