Distributing an IBO application is a very simple process.
In any IBO based application there are four essential pieces to make it work. The database server, the database file, the database client, and the application executable file.
There is no need to install the BDE or any of its SQL Links drivers. ODBC is also totally unnecessary.
By installing LIBS (Local InterBase Server) the database client is also installed automatically. So, the only part remaining is to install the database file and the EXE.
You can copy the EXE onto the machine and either generate the database automatically from the EXE using a TIB_Script component with DDL statements to produce the database or copy it into its intended location if it is already produced ahead of time.
Of course you must first have network connectivity and the InterBase Server installed on your server and configured to allow remote clients to attach to it. Often this requires that certain license keys be entered through the license manager tool provided with a production copy of InterBase.
Instead of installing LIBS on the client machine you need only install the IB Client to allow that client to establish a connection to the remote server. Then, the rest is the same as above.
Do NOT hardcode your database connect string into the EXE. If you need to change the location of a database you would have to recompile your application and update it. Use a system registry entry to contain the desired connection string for the application or provide some sort of internal storage so that the user can adjust the database connection string.
How to configure the client
