UniDAC vs. ZEOS

I'll soon be requiring multi-database connectivity and have been mulling over buying UniDAC. However, today I saw Arnaud's post on Praxis about Zeos 7.3 and am wondering if I should use it instead. I've seen a number of impressive benchmarks on this forum for Zeos, but am interested in any thoughts anyone has on pros/cons of each, use in production etc. I use Delphi 10.4 on the client and am planning to use FPC on Linux servers, but also some Delphi/Windows server implementations.

Also can anyone point me to a full list of the different databases that Zeos can connect to?

Thanks in advance, Bob

Re: UniDAC vs. ZEOS

It may be a message for the Zeos forum...

But in short, Zeos 7.3 has excellent database support, and when used with ZDBC - i.e. a its direct layer, as we do from our mORMot ORM - its performance is higher than any DB.pas based alternatives.
From our tests, UniDAC is not the fastest DB layer on Delphi - FireDAC is faster.
It has excellent FPC compatibility, whereas UniDac is behind in terms of FPC compatibility - see https://forums.devart.com/viewtopic.php?t=38418
Zeos support is excellent, and reactivity to bug is awesome.
And you will favor Open Source, so I would definitively advice for it!

Re: UniDAC vs. ZEOS

Thanks Arnaud - I've found the Zeos forum and there's a section for each database.

Re: UniDAC vs. ZEOS

Thanks for the fresh numbers!

Just a question: why didn't you include the SynOracle, SynPostgresql, SynOleDB and SynODBC numbers? It could be interesting to include the info with SynDB direct access units.

SynPostgresql can not be tested, it permanently fails: Performance tests are not comparable and only the default Port is supported..

Re: UniDAC vs. ZEOS

SynDBPostgres accept Postgres connection URL in DatabaseName parameter, port can be specified there as postgresql://localhost:5433

Re: UniDAC vs. ZEOS

@Pavel, did you ever test it? Maybay it's a lack of my knowledge, but i'm not able to.. Thus using DatabaseName := '127.0.0.1:5438' fails same as using '//localhost:5438' as you suggest. That's way

PQconnectdb

as been introduced by PostgreSQL, thougth.

Re: UniDAC vs. ZEOS

Yes, it tested and used on production

ServerName := ''; DatabaseName := 'postgres://host:port/dbname'

Didi you miss `postgres:` ?
