Description: Document Storage Systems (DSS) Veterans Health Information Systems and Technology Architecture (VistA) Service Oriented Architecture (SOA) Suite is a middleware application development framework built by the vendor to be compatible with VA VistA. This technology provides a real-time, bidirectional data and services platform for building and deploying applications with zero downtime. VistA SOA can be installed on a dedicated standalone server or as a virtual machine.

This product is available in two builds: .NET and Node.js-based frameworks. The .NET version runs on the Microsoft Windows platform as a standalone service, requires a small footprint, and can be run on virtual servers. The Node.js version can be deployed on Linux and macOS based servers. This entry covers both builds.

This technology stores data in a Microsoft Structured Query Language (SQL) Server database.

Please note that there is no dedicated webpage for this technology thus the vendor page is used in its place.
