DSI Document Systems

What DSI Document Systems does

DSI – Document Systems, Inc. is a privately-held, independent software vendor headquartered in Walnut Creek, California, that has supplied IBM mainframe software to enterprise customers for over 20 years. The company is an official IBM Business Partner and operates with a small footprint, distributing four core products targeting organizations running IBM System z (z/OS and z/VSE), CICS, and VSAM. Its go-to-market is consultative enterprise direct sales via toll-free and direct phone lines, supplemented by the IBM Business Partner channel, with no public pricing disclosed.

The company's product portfolio centers on DOCU/MASTER, a full-text contextual search and knowledge management engine that uses a proprietary 'net change' indexing methodology to deliver sub-second response times across Boolean, wildcard, proximity, and synonym-based queries on mainframe-resident structured and unstructured data. DOCU/MASTER Archivist extends this with z/OS report archival and delivery as Adobe PDF and other platform-independent formats; VSAM-Direct exposes mainframe VSAM RRDS, ESDS, and KSDS data as XML/Web Services via HTTP, SOAP, and WSDL without requiring application changes; and BatchCICS-Connect enables true 24x7 CICS uptime by letting COBOL batch programs integrate with CICS transactions without disabling files or transactions. Together, these products let organizations extend the useful lives of legacy applications and data while integrating with contemporary web, server, and cloud applications.

DSI's revenue model combines enterprise software licenses with annual maintenance and support contracts, plus per-diem or project-based professional services covering CICS application maintenance, CICS integration, VSE-to-z/OS migration, and macro-to-Command Level CICS conversion. Customer use cases are concentrated in IBM System z enterprises with data-mining, document management, and regulatory compliance requirements — notably insurance (Property/Casualty, Unemployment Insurance), government, and Human Resources Management Systems. The company maintains reciprocal technology partnerships with Virtel (mainframe thin-client web access) and CASI Software (z/OS report transformation to PDF/CSV/XML), and holds registered trademarks on DOCU/MASTER and DOCU/MASTER ARCHIVIST.
