Hi, I'm new to DB Programming in Delphi.  Can someone answer these Easy questions please concerning a single user database?

My application will be used by doctors to manage all their patients.  It will be one app for each computer, although there will be no db server.

1)  Does the client need to have some kind of DBM installed?
2)  If so (#1) what Database do you suggest?
3)  Do you know where can I find an example source of a database application?

Thanks

Tomassi.

HI,
1) Since you will be having a separate application on each computer, and I am assuming no networking, then you will also need to install the Borland Database Engine (BDE) along with your application.   Delphi 3 includes InstallShield Express, a certified install program that facilitates proper installation and un-installation of Delphi applications. InstallShield Express helps ensure that your applications co-exist well with other software that uses the BDE, such as dBASE, Paradox, and C++. InstallShield Express also makes it easy to distribute subsets of the Borland Database Engine; this is useful, for example, if you want to distribute an application that uses only dBASE tables, and you don't want to include additional files for Paradox support.

2)I would use Paradox bases database, as it has the best built -in referential integrity.

3)  As far as examples, first try experimenting with the database wizard that comes with Delphi.  Try to also get to know the TQuery component, which you will use a lot if you want to query your database for specific data. Also, look under your Delphi root directory for: \Demos\DB\MastApp for an excellentexample with source code of a master-detail type database (the most common type).

I'm sure you'll have lot's of questions when you dive into it, so don't hesitate to post them here or email me.

Good luck,
Martin Gauss

Thank you for answering Martin....one more question:

Is paradox included with delphi?...do I need to get a Paradox licence in order to distribute my application?

Thank you very much,

Tomassi

Yes, it is included with Delphi and you have the license to freely distribute your Paradox files with your application.
