delphi , database
Hi everyone,

So I'm sort of a newbie/hobbyist. I understand the basics of Delphi, including OOP principles, and I have a basic understanding of SQL syntax. Now I'd like to learn about using databases with Delphi. I'm looking for a tutorial for Delphi database newbies to help me learn to create local, cross-platform databases. Looking for info online, I'm overwhelmed with all the systems, drivers, and other things I don't understand.

The tutorials I see that are aimed at newbies like me are older, using technologies that are mostly or only for Windows (like the ADO tutorial on the old delphi.about.com site or even BDE tutorials).

Beside ADO and Access databases, I see discussion about FireDAC, InterBase, DataSnap, Zeos, and other components, libraries, or frameworks. But I don't know enough to even know if they're things I should know about! So I'm hoping someone can point me toward the kind of newbie tutorial I'm looking for ... SQLite, Access, whatever--the database engine or format doesn't matter--just a beginner tutorial for creating local, easily deployed, cross-platform databases.

Thanks, as always!

Hello,

you should use FireDAC which is included with Delphi as a starting
point. It is quite good enough for the majority of applications.

There should be some samples included with Delphi, look in the public
documents folder on your PC. There's some Embarcadero subfolder and
there are samples. Some might be for Interbase, their own database (a
relatrive to Firebird as Firebird is an open source off-spring if
Interbase) but it is easy enough to use SQLite as well or other databases.

Greetings

The way Delphi works is that most component packages work in the same
way. So if you learn one component package, the other ones are likely to
work in a similar way. Also, even if you go through an old Delphi
tutorial, alot is likely to still be true.

Which platform's are you actually wanting to target?

Delphi's cross-platform library is called Firemonkey.

You should find plenty of tutorials if you search for the following
terms (combined in different ways)

Firemonkey Database Tutorial
Firemonkey Mobile Tutorial
Firemonkey CodeRage

CodeRage is a free online Delphi conference. Most of their replays are
on YouTube now.

E.g.:
http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Tutorial:_Connecting_to_a_SQLite_Database_from_a_Multi-Device_Application_on_Desktop_Platforms

The tutorials I see that are aimed at newbies like me are older,
using technologies that are mostly or only for Windows (like the ADO
tutorial on the old delphi.about.com site or even BDE tutorials).

Beside ADO and Access databases, I see discussion about FireDAC,
InterBase, DataSnap, Zeos, and other components, libraries, or
frameworks.

Some of the main Cross platform DB access components are
FireDAC and Devart products like LiteDAC or UniDAC.

FireDAC: Only available as an addon to Pro version.
LiteDAC: Independant vendor.
Zeos: Not sure if it works with FireMonkey. There is a good chance that
it does.

All of these components work in a very similar way. Learn one, and
you'll know how to work with the others.

Firebird/Interbase is a cross platform database, but I would recommend
you use SQLite for a local db application.

DataSnap is a server side technology, for developing server applications.

That's wrong. The pro version without addon contains a limited version
of FireDAC. It can access "local" databases only like SQLLite, an
embedded version of Firebird or IBLite (a lite version of Interbase).
I'm not sure if it's allowed to connect to a full version of Interbase,
but that's the only "big" database for pro without addon then, as this
would generate further revenue for EMBT if used in production.

Enhanced in 10.2 Tokyo! Support for local databases, including Microsoft Access
database, SQLite and MariaDB database, InterBase ToGo / IBLite, InterBase on
ocalhost, MySQL Embedded, MySQL Server on localhost, Advantage Database local
engine, PostgreSQL on localhost, Firebird Embedded, Firebird on localhost

Thanks for correcting me. This was the case when XE4 was released.
