N/A
The Raima Database Manager (RDM) from Raima Inc in Seattle, Washington is a relational database management system.
Paired with Citect SCADA or System Platform, this is an excellent process historian. It also works well collecting OPC data. For basic data storage, retrieval, and analysis, this is well suited. This is not well suited for very large deployments. Multiple instances would need to be used to scale up, and the data fed into a second-tier/enterprise historian for corporate user consumption.
First of all the performance of RDM was superior compared to SQLite in my multi-user environment (about 200 users). The pricing was surprisingly good compared to other high-performance databases.
Decreased time to market, a faster and more performant application overall and lower maintenance costs.
They run on most RTOS and can be used in a cross-platform environment.
Query performance--for very long-term/large queries; the latest version which we are yet to commission has some improvements in this area
User interface--the trend, query, and Excel add-ins are basic and could do with a refresh; web-based clients are a paid add-on and less full featured, so not a true replacement
Connectivity--Wonderware System Platform driver packs are required for additional data source types, where native connectors are not provided by other products
AVEVA Historian, formerly Wonderware, was the best of the process tier historians in terms of reliability and functionality. It is still under development and not a "dead" product. It is also more cost effective than the more full-featured enterprise historians, such as PI, which our organization is not yet ready for. The feature set is at the right cost level, coupled with current support, were the key factors in the decision.
Increased efficiency, reduction in labour for preparing reports--data is available to be queried and reported with less effort
Increased production efficiency--near real-time data availability and comparisons to historical data has been used to make faster and better operational decisions
Increased reliability--data has been used for maintenance optimization and planning purposes
