architectures si l'une était vraiment meilleure que l'autre. Si vous n'êtes pas certain de quelle architecture choisir (peut être que vous trouvez tout cela un peu trop tech- nique), utilisez ces règles simples: verrez pas la différence en termes de performances. Notez que vous pouvez toujours basculer d'une architecture à l'autre plus tard; vos applications et vos bases fonctionneront toujours (sauf si vos applications (serveur embarqué), mais c'est une configuration complètement différente et n'est pas faite pour une architecture client-serveur.

For Linux, Superserver packages with FirebirdCS. For Windows, there is a combined installation package; you choose the architecture during the installation process. Embedded Server for Windows On Windows platforms only, Firebird – to the client machine. Note: always copy the tools from a Superserver kit, regardless of the architecture of the server(s) you're planning to connect to. Tools from Classic distributions terminate immediately

An embedded server has the SuperServer architecture and hence exclusively locks any database it attaches to. This is intentional. Installing an Embedded
