Oracle Coherence vs. Raima Database Manager (RDM)

High Volume data storage and processing is a critical initial use case of Oracle Coherence. Right after data storage, data processing is also handled by the software, i.e.; this includes manipulating data on the go, using cache L1, L2, and L3 levels available, In-memory scaling, fast access to data with RBAC, Scaling web technology applications with High Availability, and Disaster Recovery. Less Appropriate: Low-volume data, less frequent data processing, and applications that do not require high availability or quick response times are not appropriate candidates for Coherence.

Works very well in applications designed for IoT devices where performance and footprint are of great importance.

• Performance. Superfast resolution of complex data grid queries.
• Reliability. Availability domain support for disaster recovery.
• Programming model. Frictionless API for use with Java 8.

• 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.

• I can't really come up with too many flaws, but possibly a bit expensive considering there are good open source caches like Ehcache.

• I would like to see REST API with a GUI for administration

Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.

DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications. On the otherhand Oracle Coherence has more a flexible configuration and better performance. Also the Oracle configuration and monitoring tools are more convenient and informative than the DataSynapse ones.

RDM performs way better than SQLite when the database is larger and has multiple users.

• In my current project, it is yet to be decided as we are on the way to make it live for users. But I am sure it will be an added value to obtain timely calculations.

• Decreased time to market
• Decreased maintenance and service costs on hardware.
