2. Agenda New Architecture PI JDBC PI OLEDB 64bit (x64)
Motivation
PI SQL Data Access Server (PI SQL DAS)
Roadmap
PI JDBC
PI SQL DAS 1.0
Cross Platform Demo
PI OLEDB 64bit (x64)
Details
PI System OLEDB Provider 1.0

Future (Tag based data, Event Frames,...)

3. RtBaseline Services for Thin Clients
Data Access - Overview
PI Data is available via common standards
Data Access
RtBaseline Services for Thin Clients
OLEDB
ODBC
OPC
WebServices (i.e. RtBaseline Services) – Provide Data to Web Applications
OLEDB – Data Access via SQL Queries
ODBC – Data Access via SQL Queries
OPC DA/HDA/UA – Data Access to the PI System via OPC Standard

4. Data Access Via PI OLEDB
PI OLEDB provider allows applications (OLE DB consumers) working with PI data through SQL queries:
Next Generation – Motivation:
renew PI OLEDB Architecture
introduce JDBC and other data provider standards
support „PI System“
Client Application
PI Server
SQL Engine
OLE DB/ COM
OLE DB Consumer
SQL Queries
PI OLEDB Provider 4

5. Non Time Series Data Sources
AF in the PI System
Data structured and organized by Assets
Spans multiple PI Systems
Incorporates non time series Data AF

6. New Architecture
Multi-standard and multi-platform architecture One connection allows querying multiple data sources
Standard implementation separated from SQL functionality
Prepared for heterogenious query engine
Consumer / Client
Consumer / Client

10. PI JDBC PI JDBC Details Limitations
bridge to PI OLEDB (Type 1 JDBC driver)
based on JDBC 4.0 API (Java Platform SE 6)
same table structure, same SQL functionality as PI OLEDB
Multiplatform
Will work on many Linux Distributions
Testing concentrates on Windows, Novell Suse Linux Enterprise Server and Red Hat Enterprise Linux
best option for JAVA based development
Limitations
PI OLEDB is multithreaded but not designed as backend
additional communication infrastructure overhead
amount of supported OS limited because network component is OS specific

11. PI JDBC Demo getSnap JDBC application
Compile in Windows version of Eclipse
Run on Windows and Linux without additional work

12. PI JDBC Demo Linux (ubuntu)
DBVisualizer allows to access and explore any jdbc Driver
PI JDBC (Bridge) talking to PI OLEDB

13. PI OLEDB 64bit
can coexist with 32bit PI OLEDB version on 64bit Windows (x86-x64)
transparent to applications if both versions installed
required for 64bit SQL Server Linked Server
requires 64bit PI SDK
comes as seperate setup kit

14. PI OLEDB 64bit
check version via architecture column in piproductversion table

15. PI OLEDB 64bit
Increased performance for large resultsets

16. PI System OLEDB v1 Architecture Details
PISysOLEDB version 1
Windows based
Linked to AF SDK (bypass object model)
Access via AF Server
Read-only
