Overview
Stardog
Stardog helps you break down data silos by creating a flexible knowledge graph layer over your existing infrastructure. Instead of moving data into a central warehouse, you can leave it where it lives—in SQL databases, NoSQL stores, or cloud apps—and query it as a single, unified source. This approach allows you to see relationships between data points that traditional systems often miss.
You can use the platform to power complex data discovery, fraud detection, and enterprise-wide search. It uses a semantic layer to ensure your data remains consistent and understandable across different teams. By automating the mapping of disparate data sources, you reduce the time spent on manual data preparation and can focus on gaining actual insights from your information.
TrueNAS
TrueNAS gives you complete control over your data with a powerful, open-source storage operating system. You can transform standard hardware into a professional-grade storage array that handles file sharing, backup, and virtualization tasks simultaneously. It uses the self-healing ZFS file system to protect your files against corruption, ensuring your digital assets remain safe and accessible for years to come.
You can manage your entire storage environment through a clean, web-based interface without needing deep command-line knowledge. Whether you are a home hobbyist setting up a media server or an IT professional managing petabytes of enterprise data, the platform scales to meet your specific capacity and performance requirements. It eliminates vendor lock-in by supporting a wide range of hardware and providing seamless integration with major cloud providers.
