DBfree and portable devices
DBFree offers a suitable solution to port
your existing data on handheld devices
: just build a standard web
application with a responsive layout and provide you user our DBFree gateway
to connect with it.
DBWG (DBFree Web Gateway) is currently under revision to be made compatible with DBFree V41 and temporarly unavailable: please refer
to mobile.dbfree.org for more informations.
DBFree is Open Source
(except MaxScript and some utilities)
- All the code offered with
DBFree, including its interface, is released as Open Source. Neverthless the MaxScript
interpreter necessary to some of those pages is not provided as such but, even if free of any charge,
is released under a license (as well as some other utilities included in the bundle).
- You can use DBFree libraries
and MaxScript freely, on any computer, for staging and for production use,
including workstations, virtual machine and web server in a commercial
- You can sell or market the
applications you made with or for DBFree and MaxScript.
- You do not need to register or pay for libraries accompanying the DBFree original
distribution and for the MaxScript interpreter (anyway notice that some optional software products,
third-party libraries or manuals offered on this site may require a payment).
If you feel confortable with HTML
then MaxScript will be a
natural step forward
With DBFree you will be productive literally in minutes
Just take a look at this example
You don't like HTML?
If you are accustomed with older procedural languages
as BASIC, PASCAL etc. then MaxScript is the
With this language, you can minimize the hassle
of meddling with the
long and wordy instructions
typical of HTML pages. at least as far as possible.
You can even start with almost no knowledge of HTML
,to then learn it naturally during development of the project.
Just have a look at this page
You were cut off because of the web? Jump on DBFree
and you'll be back in business
just in few hours. Especially if you want to
reach portable devices as smartphones and tablets
:they have a strong affinity with the old terminals (and the way we dealt
with them) bigger than you'd ever thought.
And procedural programming couples very well with applications made to run one at a time, one page at a time, on small displays.
MaxScript offers maximum freedom of choice when it comes to writing code. There are practically no impositions except
the basic technical requirements of the compiler (one statement per row, one instruction per statement, and little more).
No matter what you are used too, as soon as you keep in mind that MaxScript is not an Object Oriented language,
you can adopt any programming style you like.
MaxScript (in its DBFree implementation) is so flexible that gives you even the chance of rewriting the language itself, if you like so.
Old Clipper/xBase fan?
There is no better place than this to recover the spirit of the Roaring Years Of Personal Computing
And this happens just now, right when the personal computer is at sunset, replaced by a host of intelligent devices completely beyond our control.
Here, with the DBFree Project, we attempt to regain possession of amateurial computing
We do not have the aim to change the world, or shake the IT community with innovation, but at least to come back to have fun with coding, that's for sure.
No problem. MaxScript is by far one of the easiest language to learn around.
If you're intrested into practical purposes
and you still have vague school memories of what a web page should look like then you already have
the basic skills to start.
Curious? Just have a look at this classic "Hello World!" example
You may also want to take a look at this page for an explanation on why you my want to use DBFree.
Well, probably this is not the product for you.
Today developers work in teams. And DBFree has been designed with only one thing in mind
: keep all the development and deployment process
under control of a single person
Mind you - MaxScript is everything but a toy
: at its core is not less complex than Phyton, PHP or other scripting languages, but
it's not Object Oriented
, has no IDE
, it is not WYSIWYG
and first of all, at least in our DBFree implementation,
is totally open
: there is no way to hide the code
you write and deploy to users.
There is no (simple) way to obfuscate the code and this was done deliberately.
Otherwise why would we call it DBFree
Using DBFree for commercial purposes
Even if DBFree intentionally does not offer a way to hide the source code, this doesn't strictly mean that you can't market commercial solutions
on top of it: simply you can't do it in the usual way, deploying your application directly to users.
If you plan to do something commercial you must market it as a service
instead that as an application
(i.e. installing everything on your
not to user's ones.
DBFree V4.1 has been re-designed just for that: to make you develope at home
and then place everything in the cloud
And eventually - but this depends on you - marketed under the SAAS (software-as-a-sevice) business model.
A business run by individuals
, not by large software companies.
Just to remain true to its original philosophy.

What's DBFree good for?
DBFree is a flexible tool: by changing its configuration you can use it for different purposes.
Using DBFree for self-learning
If you've always wanted to learn how to build software yourself — or just whip up an occasional script — DBFree it's the perfect place where to start.
If you're curious about how to become a programmer, you can get off to a running start using the integrated MaxScript Console.
A common pitfall for beginners is getting stuck figuring out which programming language is best to learn first: there are a lot of opinions out there,
and this may be confusing you even before to start.
Well: just install DBFree and in ten minutes flat you'll know if learn programming is the right path for you.
In the end, language doesn't matter THAT much. What is really important is the understanding of data and control structures and learning MaxScript will
give you a deep understanding of both.
Every language have elements that you'll use in other languages and concepts that you will reuse many times no matter the platform you're on:
DBFree is completely
HTML-based, and learning MaxScript will give you a good understanding of that, which at the moment is the most reusable competence you may imagine.
Using DBFree as personal organizer
Need to keep tracks of your appointments? Do you need a personal agenda or an address book?
There is a lot of software that let you do this (literally tens of hundreds), so why using something like DBFree?
Well, DBFree let you share your data among all your internet-enabled devices
(including smartphones), wherever you are. And you can do it
without ever writing a single line of code (or even knowing how to do that).
AS soon as you know where to put your hands on your ADSL router configuration you're done.
Using DBFree as Web Server
Right after installation you can set DBFree for acting like a web server on internet (or on your intranet).
The configuration of the whole system is utterly simple, assuming you have full access to the router that connects you with internet.
The main benefit of using DBFree on your own telephone line is that you will have at your disposal all the resources of the PC you connect: an huge hard disk
(an all its content), immediate updates of shared data and all the processing power of the CPUs without having to share it with anyone.
You don't even have to keep you PC on all the time: you may keep a cheap static external web site hosted by a provider and provide a link to your home-hosted
one warning that this is only active during office hours.
Using DBFree as staging server
Assuming you have enough experience you can easily set your home PC as staging server, where you develope and test your web applications, and then
deploy to a production server elsewhere (ideally in the cloud but not necessarily).
DBFree already comes with the basic tools for starting (specifically the PSPad editor) and, in facts, the whole DBFree GUI have been developed
only by using the DBFree selection of tools: PSPad for source editing, DBManager for database designing and - of -course - DBFree embedded server
for testing locally.
Using DBFree as production server
You can also use DBFree for production: if all you want is to run a portal for your firm DBFree will be up to the task.
Anyway if you want to host more than one Web Site at a time you will need something else.
Assuming you have the necsary skills (and patience) Micorosoft IIS8 will serve you right: albeit a little complex to configure it is a robust
and reliable solution for almost any kind of utilization. It works well with MaxScript (actually it is the server behind this site) and moreover
it is absolutely free.
Another simpler solution, that does not require special competence other that those acquired by installing and using DBFree is to get DBWEB, the
datacenter server for DBMax (and DBFree).
Using DBFree for automating existing web sites
You can use DBFree for serving dynamic pages while the large part of your website remains static and hosted outside.
All you have to do is to prepare web forms on your external web site and address the result (the target page of the form) to the one on your DBFree-powered
PC at home or office.
By using iframes
or popup windows you can make the whole process seamless without any changes on your existing stsatic site (except, obviously, the
pages where you will put the web forms).
DBFree Database Engine (DDE)
The database features of DBFree
DBFree reads and writes DBF files natively, without the brokerage of any other software: this means nothing to install, nothing to configure,
nothing else to run (and monitor) on the server.
Even if you can use any external DBF utility for manipulating the DBF tables (including commercial products like those offered by dBase inc.)
DBFree offers some utilities by its own.
The best, at this moment, is the DBManager:
Similarly to any other application for DBFree, the DBManager comes with full source code, ready to be used or to serve as
foundation for your own customized version.
DBManager is also a great place to start learning how a DBApp is made and how to program using MaxScript.
