HEC-DSS is a data storage system developed by the US Army Corps of Engineers Hydrologic Engineering Center (HEC). HEC-DSSVue (or DSSVue) is a utility program, also developed by HEC, to create and manage the data stored in HEC-DSS database files. (DSS files have extension type .dss.) Since ResSim relies on HEC-DSS for storing and retrieving all of its input and output time-series and paired data, DSSVue is included as an integral part of ResSim.
