eNVy Systems — Engineering Solutions for Legacy & Virtualized Platforms

What We Do

Deep Systems. Hard Problems. Real Solutions.

We don't just support legacy systems — we extend them, integrate them, and virtualize them. When off-the-shelf tools don't exist, we build them.

▦

MANMAN/OpenVMS — Full Stack

All MANMAN packages — MFG, Finance, Logistics, Shop Floor, Planning, Purchasing, Lot Tracing. Deep integration expertise from the ERP application layer through Oracle Rdb/Codasyl DBMS, the OpenVMS operating system, and the underlying physical or virtual platform.

MANMAN · Oracle Rdb · Codasyl DBMS · OpenVMS · Charon

MANMAN Integration — Real-time data replication, Windows desktop integration, cloud bridge services, and custom middleware extending MANMAN to modern platforms including AWS/EC2.

Full Stack Support — MANMAN Application → Database (Rdb/DBMS) → Operating System (OpenVMS) → Virtual Platform (Charon/Azure/AWS). One team, all layers.

→ Case Brief: RestAWS — Real-Time Cloud Bridge
