Does anyone know any DBMS written in (Object) Pascal besides TDBEngine
and Halcyon? Either relational or object oriented?

I dont know if are FP compatible:

- NexusDB  - commercial - http://nexusdb.com - very mature
- Flash Filler - open source - seems abandonware -
http://sourceforge.net/projects/tpflashfiler

Why you want a database in pascal?

If you need an embedded database you can use sqlite or Firebird.

Hi,

DBISAM and ElevateDb from Elevate Software
(http://www.elevatesoft.com/) are written in Object Pascal.
IIRC, DBISAm is Delphi/CBuilder only, and ElevateDB can be compiled
with FPC.

Regards,

Gerard.

I've heard that the SAPDB database originally was in Pascal (but afaik
it has been changed after a complete rewrite)

what compiler do they use such that they decided to port it from
Pascal?

I don't think the reasons are technical, more corporate policy (taken
during a series of mergers)

It's really bothering. People stopped saying me that when I ported my
CG libraries from C++ to Object Pascal.

that's actually the main reason why corporate backed-up languages hold
the market. Policy over efficiency...

There might have been other reasons:

- The Pascal Compiler they used probably did not support OOP
- It might not support all the platforms they wanted to target (AIX,
Solaris, HP-UX, Iris, Tru64 etc)
- Maybe it was difficult to get Pascal programmers in a market
dominated by C++
