They keep the HD manufacturers in business with them, of course... What are External Tables? The most elegant, IMO (and perhaps easiest), way of getting external data into your DB: just declare a table as residing not actually in your db-file/"table space", but in an external (flat ASCII) file. If you want to move data into the DB permanently (which I assume is a requirement in order to get more efficient indexing, and prolly stuff like referential integrity and so on), just do an SQL copy to another, regular DB-internal, table. You'll have to define field delimiters or column positions, perhaps line-end styles, and so on -- but at least you don't have to mess around with separate programs, which of course require that anyway (coughSQLLoadercough), any more. Hmm. I guess I would rather just use the [link\|http://www.us.postgresql.org/users-lounge/docs/7.2/postgres/sql-copy.html\|COPY] command and be done with it... Does Interbase have polymorphism/inheritance for its tables? Not that I know of... What is that? [link\|http://www.us.postgresql.org/users-lounge/docs/7.2/postgres/inherit.html\|http://www.us.postgr...gres/inherit.html] Other interesting features of Postgres include the geometric types, user-defined types/functions/operators, and (one of the best things) the ability to use nearly any language you want to as a stored procedure (with a little extra work to integrate it first if it hasn't already been done).

If so, then that (along with roles and views and Idunno what all) is among the many IB/FB features I neglected to mention. As opposed to UDFs, which IIRC I did mention... :-) So what are you saying -- that Larry is collecting a percentage from Seagate, Maxtor, et al? Christian R.

Post #64,480 by CRConrad 11/22/02 10:51:43 AM Reply	Wow, cool; the FB dev list is only now talking about that... ...kind of thing. Or, OK, they've been mentioning it, on and off, for a bit over a year AFAICR. But it ain't there yet. (Also somewhat reminiscent of how to build TField-descendant object classes, for client-side apps that attach to different kind of DBMSes, in Delphi; those "save/restore functions" are analogous to the getter/setter methods for the AsString property.) Cool to see that PgSql seems to have copied IB's basic "multigenerational" ("multiversion", in Postgres-speak) architecture, too. (Doesn't seem quite consistently pervasive, though.) Yeah yeah, I'll lay off the bashing... If the freaking WORLD lays off the hyping! :-) Christian R.

People use it for the real world too, though. :-) Some of the contrib items are pretty nifty as well, like the fulltext indexing I use here.
