Architecture

PI SQL Client OLEDB is an implementation of the OLE DB standard based on the OLE DB API.

Communication from PI SQL Client OLEDB to the PI System requires using PI SQL Data Access Server (RTQP Engine) which serves as a gateway between PI SQL Client OLEDB and the RTQP Engine that executes the queries. It provides secure network communication through Net.Tcp or HTTPS to PI SQL Client OLEDB.

Note: For HTTPS connections, PI SQL Client OLEDB supports Transport Layer Security (TLS), versions 1.0, 1.1, and 1.2. The TLS version is negotiated with PI SQL DAS and depends on its version and the operating systems involved.

PI SQL Data Access Server (RTQP Engine) runs on Windows and PI SQL Client OLEDB is supported on Windows only.
