Today's guest is
Carlos Cantu (
Firebase.com.br), speaker at
Firebird Conference 2014.
— Carlos, why do you think people will be interested most of all in your talk?— My talk about Data Auditing logs is based in a solution that I have been using in the last 6 years, in my own ERP. It was created because from time to time I got contacted by customers saying that some information simply disappeared from the database, or got modified without nobody editing it, suggesting that the software had some bug <g>. With auditing logs, it became really easy to show/prove to customer what really happened, allowing you to keep a history of everything that was done inside the DB. The other talk is about Numerics in Firebird. Due to the several different datatypes available for storing numbers in Firebird, each one with different characteristics/behaviors, it is not rare that developers get lost about its differences and what would be the best type for a specific requirement. This talk will try to answer those questions, as well show some tips, tricks and side-effects that sometimes are unknown by the developer, showing also the actual rules used in the math involving numeric/decimal types.
— What do you like most of all in Firebird? and What is your most favourite feature/improvement in Firebird 3?— I use Firebird since its first release, and what I really enjoy about it is the fact that it is small, easy to install and configure, very stable, has low maintenance and, of course, it is totally free! Firebird 3 is long awaited for its improvements related to extracting all the potential of SMP machines, even when shared cache is being used. Of course, this feature is a must in the currently world where SMP machines became the standard configuration for servers. But FB 3 also brings very nice features, and I really enjoy the fact that now we can encrypt the database file and the wired communication, and the wire protocol was improved allowing better performance in high latency networks (internet).
