Fine Tuning

Take Control of Your Data

Our core value is Empowerment. For developers, this means having absolute control over your application. We’ve built c‑treeACE with this principle in mind and that’s what makes it an engineering-level database. In today’s environment this is critical as developers are under increasing pressure to produce innovative applications fast, while ensuring they stay reliable and secure. This takes more than traditional databases offer—it requires precision and control.

Since 1979

The Most Robust No+SQL Database Technology

FairCom has been refining its NoSQL technology for over 35 years. Built upon the solid foundation originally called ISAM (Indexed Sequential Access Method), c‑treeACE has become the most robust No+SQL multimodel solution available, well suited for a broad range of transactional applications. It provides a very strong ACID key-value store with full SQL capabilities. Our cross-platform support (Unix, Linux, macOS, Windows), scalability, and high availability combined with our long history of stability and innovation have been noted in the industry for their strength.

Fast and Consistent

ACID Transactions with NoSQL Performance

A challenge facing NoSQL solutions is the tendency to achieve scaling through clusters that are not synchronized in real-time. This results in “eventually consistent” (BASE) data rather than the ACID-compliant transactions that ensure accurate, up-to-date data throughout the system. With ACID-compliant transactions and NoSQL performance, FairCom has a proven track record providing data integrity for financial institutions and other mission-critical uses.
