dbExpress is a set of thin, native drivers that provide fast access to database information.
You can deploy a dbExpress application either as a standalone executable file or as an executable file that includes associated dbExpress driver DLLs.
DbxClient drivers, currently used by Blackfish SQL, require DbxClientDriver bpl to be deployed if packages are used. Otherwise the entire driver can be linked into an executable file, and no additional package or DLL needs to be deployed.
For database applications using Dynalink drivers, you cannot deploy a standalone executable. Instead, you can deploy associated dbExpress drivers and DLLs with your executable. If you are using DataSnap, you need to include the DataSnap DLL. The following table lists the appropriate DLLs and when to include them:
