Not only will you have performance and corruption issues, you'll also have problems with the lock file. And security is a pain to manage.

I have many years experience with several database products: Foxbase,
FoxPro, MS SQL, Access, Postgresql, AS400 DB2. Compared to any of the
above Access is a toy. Case in point; in my office we have a product
which is "multi-user" based upon Access. When the users, there are
only four of them, start pumping data into the database all at once,
the product fails. We then contact the vendor then replies with a
TechNet article from M$ which explains that Access should not be used
as a multi-user database.
Also, take note many many projects start as just a simple little job
and then take on a life of their own.
Oh what about security and user management. And what about backups.
Who is going to hang around until all the users are finished to backup
the database?
Considering Postgresql is free and actually works. There is no
decision.
good luck

This is true, but there is a problem when you are developing an aplication that must be easy to install, because the person who will probably install the system is a PC user, not a Software Ingenier neither a DB Admin. In these cases, postgres, mysql, sql server, ... and other DBMS needs the interaction with an experimented person who knows who to install and configure the DBMS for dealing with the application. Often, these sceranios, the application could be monouser and selfinstallable. In these circunstances, Access could be a option. In 80s, DBase was the poormen database, since 90s is Access. I kown a lot of comercial applications, that todays uses DBase and Access database file structures. Therefore, do you know a better Open Source DBMS than Access, that is easy to install and integrate with your applications ? I mean, there is an Open Source DBMS whose features are bettween Access or DBase and Postgress/MySQL ? Thanks.

What is your target environment? We sell a commercial program (http://www.canit.ca) that uses PostgreSQL internally. For our Red Hat 8 and 9 Linux targets, installation is extremely simple; it goes something like this: ./install ./init-database I would imagine that you could fairly easily write comparable wrapper installation programs for PostgreSQL on other platforms.

I understand what you are saying, but I would submit that convenience is never a substitute for data integrity. -- Until later, Geoffrey esoteric@3times25.net Building secure systems inspite of Microsoft
