Overview
Alation
Alation helps you make sense of your organization's vast data landscape by creating a single, searchable home for all your data assets. Instead of hunting through spreadsheets or asking colleagues where to find specific reports, you can use the automated catalog to discover relevant data, understand its context, and verify its quality instantly. It uses intelligent suggestions to surface the most popular and reliable datasets, ensuring you always work with the best available information.
You can streamline your data governance and compliance efforts without slowing down your team's productivity. The platform automatically flags sensitive information and tracks data lineage, so you know exactly where your numbers come from and who has access to them. Whether you are a data analyst looking for a specific SQL snippet or a Chief Data Officer overseeing enterprise-wide governance, Alation provides the transparency you need to build a truly data-driven culture.
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.
