Обсуждение: Example Database
I am rather new to PostgreSQL.What I am looking for ist this: An example database that demonstrates the usage of all the core PostgreSQL features. It is one thing to read extensive documentation, but it is much more intuitive for me to see an example database, that demonstrates the whole thing interacting. I mean, not just the basic elements, but an optimized (and maybe nicely documented) database getting the best out of views, triggers, indices, rules, stored procedures and so on - maybe even a reference database from the PostgreSQL developers themselves? Have been searching for some hours now, but did not succeed. Maybe I am just being blind. Thanx for any hints! Regards, Erwin Brandstetter

Postgres has enough features that I would guess you're not going to
find a database that uses all of them.
You'll probably find it a lot easier to learn postgres by thinking of
something you want to do and trying to solve the problem with postgres.
I find it really difficult to learn a new development tool without
having a particular problem to solve.

I almost chimed in earlier, but I'd certainly second this. As far as the freedom Postgres offers in terms of flexibility of design, there's no way any single DB will illustrate it well. I started off using it becuase it was a real database in the free space, and then started using other features when they made sense. The ORDB stuff I've only used once; I have to admit that I like a fully relational database. But there are cases I haven't seen... The views/rules/triggers capability is priceless. Or, rather, Oracle will put a price on it for you, which is significantly more than Postgres.

You can look at the database generated and tested when you run make check on source. That should cover things fairly well.. Of course, truly all encompassing database is bit difficult to construct..:-) Bye Shridhar -- Heller's Law: The first myth of management is that it exists.Johnson's Corollary: Nobody really knows what is going on anywhere within the organization.
OK. I understand that you prefer a different approach. For my part, I like to combine different approaches. I understand also that you consider it impossible to put all the stuff into one database. I think it is possible after all, but that is not the point here. My request remains. I am looking for example databases that demonstrate good style in using and combining the features of PostgreSQL. I am sure there is something out there in the net. Would somebody be so kind to point me there?

Well, that was nice but in case somebody misses the point of joke, from the website.. ------------- The CIA World Factbook wfb2sql has been tested with the Factbook 2003 and 2002.

Well, actually, no, I was talking directly about the CIA itself. Am I dating myself by presuming that most people think of the CIA a a bunch of ultra-right-wing incompetent spooks that go around toppling "freely" elected governments? > ------------- > The CIA World Factbook > > > wfb2sql has been tested with the Factbook 2003 and 2002.

Well, even if that remains a topic of discussion, it is going to get irrelevant here pretty soon. I suggest we stop. Shridhar

Yes, this would be very nice indeed. Oracle is an extremely complex (overgrown)database with a ton of features, but it ships with a set of example schemas that show off a variety of features pretty well. I'm speaking of the set of schemas that try to model a company: OE, HR, etc. SQL Server ships with Northwind and pubs, as another example. But, we would need a good supplementary document that goes along with whatever materialized, perhaps guiding new users along in a tutorial manner. -- Michael D. Allen mallen@erhs.la
Informix has its "stores" demo database (more as a training exercise that a real demo); some of the extensions include extensionsto the stores db. Not sure there aren't two things: a) a place to show off features to prospective users. Ideally it tells how it works as well. b) a playground/demo area for those who have installed one. I think this thread relates to (a); the SQL demo and informix' demo are both more in category (a). Greg Williamson DBA GlobeXplorer LLC -----Original Message----- From: Michael D.
