Every Pervasive PSQL database that you expect to access using an ODBC application must have a DSN that identifies the database. A DSN that points to the Pervasive PSQL database engine is called an Engine DSN. Engine DSNs are 32-bit only and are deprecated. A 32-bit DSN that points to an Engine DSN or to a named database is called a
Client DSN. A DSN on a 64-bit operating system is simply referred to as a 64-bit DSN, without designation of Engine or Client.
Figures 4 shows possible DSN configurations.
Pervasive PSQL servers are also clients. The client components of Pervasive PSQL are installed with every Server engine or Workgroup engine. So you can use your server machine to connect to other servers as a client. Pervasive PSQL
clients can connect to remote machines where a Pervasive PSQL Server engine is installed.
