What is Delphi and how it works ?
● Delphi is an IDE : integrated development environment.
● Delphi use a language to code : Object Pascal.
● Delphi give us a lot of libraries and coding interfaces.
● And finally, Delphi has visual and nonvisual components for
designing user interfaces.

● Current programs can run on Windows, Mac, Linux, iOS and
Android.
● Let me show you how to do with Delphi 11 Alexandria.

What is Delphi and how it works ?
● In Delphi, a program is a project.
● You can create Windows only programs with VCL projects.
● You can create multiplatform programs with FireMonkey
projects.

How to draw user interface ?
● Create a new project (VCL or multiplatform).
● Delphi will add a form, the canvas where you’ll draw the user
interface.
● Simply drag & drop your components from the components list
and it works…

Using databases (client/server, local or in memory)
● In the past we had the Borland Database Engine (BDE) but it’s
deprecated and was replaced by dbExpress, dbGo and now
FireDAC.
● With FireDAC you can manage databases directly from the IDE
and of course in your projects.
● Add a connection to your database, add queries or tables and
link them to visual component for displaying or editing your
data.

How to add screens in a program ?
● In no code mode, you’ll have to use tab controls to simulate
screens and standard actions from action lists to go from one
screen to another.
● Only one form is needed, but beware : it’s better to know some
Pascal commands to show / hide / activate other forms.

How to access web API ?
● Delphi has a TWebBrowser to display HTML pages.
Use it to show local documents or web sites.
● You can also use TRESTClient, TRESTRequest and other
TRESTxxx nonvisual components to access an http/s server
and get its answer as a table in memory.
REST Debugger is a free tool to use to configure those
components. It’s available from Embarcadero website or in
Tools menu option of Delphi.

Coding a CRUD application without coding
● Let’s code a simple CRUD application with only drag&drop in
Delphi form editor.
● This sample project is available on GitHub at
https://github.com/DeveloppeurPascal/Coder-sans-coder-
Delphi-en-mode-nocode-c-est-possible

You want more ?
● Using Delphi for creating simple database apps is easy and you
don’t need to know how to code.
● Use it for your personal databases, for sample projects or
prototypes.
● You also can use Delphi without coding during Startup Week-
ends or hackathons if you need a program or mobile app to
explain a concept or win a challenge.
