If, with that, you get a complete portable embedded RDBMS which is 1:1 compatible with it's big server-brother my choice is easy. Interesting. I don't know how firebird works without its .conf file, perhaps it has default value for everything. The config file supplied doesn't have *any* settings in it.

To put it differently, if i wanted to make an application to associate tags and colors with images (for fast theme lookup), i'd use Sqlite. If i wanted to make a bookstore chain application, i'd probably use PostgreSQL.

Possibly, but if there is no need to be networked then this adds extra baggage (ie. bloat) for no reason at all. Sqlite is a tiny db designed specifically for local use, used in a ton of places (including Firefox and almost everything made by Apple these days) and has some of the highest quality source code.

But it looks like setting up postgreSQL with a pre-existing database from the CD and all the actual data, taking into account whether the desktop already has postgreSQL installed and simply the size of postgreSQL (and running it as a service), makes it not such a good fit for my application. I want the app to be simple and quick to install and use for end-users. Maybe you should look at Firebird. z. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Embedded/small database
Hi guys, I asked advice a long time ago on a small/embedded database that could be used for a desktop application and distributed by CD as part of the application.I got a variety of answers including mySQL, sqlite and others. At the time I was very partial to somehow using postgreSQL, because I had had good experiences with it in the past and also because of postGIS (the application should include a spatial/GIS component). But it looks like setting up postgreSQL with a pre-existing database from the CD and all the actual data, taking into account whether the desktop already has postgreSQL installed and simply the size of postgreSQL (and running it as a service), makes it not such a good fit for my application. I want the app to be simple and quick to install and use for end-users. I have decided to go with good old dbase (.dbf files), simply because this is what many GIS's use, at least for their non-spatial data. I have three questions: 1. What is your opinion on dbase for this use case? It will be a personal Decision Support System/Expert System that will use a combination of pre-compiled data (stored in the database during installation) and data entered by the user (added to the database during use). I would like things like referential integrity etc. to work as it should in a database, even though it is small. What would be you alternatives and why? 2. What tool would you recommend for actually creating the database, integrity etc.? I used Borland Database Engine all those years ago (it came with Delphi), but suppose there should be better (and open source) options now. MyDBF Studio? Or something else? 3. I see on the wiki that there are still issues with the TDbf component for Lazarus. What would be the best option to access the .DBF files? (And why?) Thanks again, Chavoux -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
