Overview
Astera
Astera offers a comprehensive, no-code environment where you can handle everything from data extraction and integration to warehousing and EDI. Instead of juggling multiple disconnected tools, you get a single interface to build automated workflows that move data between on-premise systems and the cloud. You can easily clean, transform, and validate your information using a drag-and-drop builder that eliminates the need for manual scripting.
The platform is designed to bridge the gap between technical and business users, allowing your team to gain insights faster. Whether you are automating complex invoice processing with AI-powered extraction or building a massive data warehouse from scratch, you can manage the entire process visually. It scales with your growing data needs while ensuring high quality and governance across your organization.
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.
