Data Historian

High-speed, fault-tolerant logging to databases such as MS SQL Server, Oracle, mySQL, SQL Azure, PostgreSQL, Cassandra, MongoDB, MariaDB, SQLite, InfluxDB, and Access. Log IIoT data to multiple destinations at once with Store and Forward functionality to local and remote databases in an open format.

Product Overview

The OAS Data Historian software allows you to log data to SQL Server, Oracle, Access, MySQL, Azure SQL, PostgreSQL, Cassandra, MongoDB, MariaDB, SQLite, InfluxDB, and CSV files based on event, continuously, time of day, or on data change in both wide and narrow table formats.

The data source can be local or remote without exposing your database. With OAS store and forward feature built in you will never lose records on an network failure. OAS implements edge computing with its Distributed Network Architecture to process and retain data at the source for up to 1 million data points per OAS Data Engine.

Never lose data on network or database engine failure. The OAS Data Historian 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.

Supported Data Destinations

Log data to one or more locations simultaneously, each with configurable parameters so data is targeted for each destination data store.
