Open Format Data Logging
Once data is logged, you are free to access it with your own or 3rd party tools for reporting or analytics
Feedback Verification
Communications handshaking can provide confirmation to controllers data has been successfully logged.
Automated Setup
Set up data logging for all of your data using One-Click Database
Data Accuracy
Data from each source is processed on-premise in a first-in, first-out (FIFO) manner. This approach ensures that all received data is preserved, not just the most recent value. Maintaining full data accuracy is essential for all applications that depend on the data that is logged.
High Speed & Scalability
Log to more than 10,000 separate tables per server up to 100 nanosecond resolution. Log up to 2 million values per second to local or remote SQL Server.
Zero Data Loss
Our historian database software buffers data in real time. If communications is lost to the destination database, or if the destination is unavailable for any reason, no data is lost. As soon as communications are reestablished, all data is transferred at high speed.
Extensive Database Support
Our SCADA data historian supports a wide range of database platforms, including: MS SQL Server, SQL Azure, Oracle, MySQL, PostgreSQL, MongoDB, MariaDB, Cassandra, SQLite, InfluxDB, Amazon Aurora, Amazon RDS, Amazon Redshift, Google Firebase, MS Access (Windows only), and CSV Files.
Custom Logging Behaviors
You have unlimited options for how and when you want data to be logged. Data Historian supports both continuous time series data, and event-based data recording. Logging can be enabled and disabled based on other conditions or calculations within the system, as well as a unique Snapshot Logging option for logging data leading up to an event, allowing you to analyze data that may have led up to the event itself.

Common Questions
What databases work with the OAS Data Historian?
The OAS Data Historian supports a variety of databases, including MS SQL Server, Oracle, MySQL, MongoDB, InfluxDB, and even CSV files.
Does the Data Historian prevent data loss during network outages?
Yes, it has a Store and Forward feature that buffers data, so you won’t lose anything even if there’s a connection issue.
Can I customize how data is logged?
