VISTA supports the development of these applications by providing a framework of Kernel, Fileman and M (MUMPS) • Universal SQL access to VISTA Databases • M code is not compiled or linked: Thus allowing incredible degree of integration between applications
Proprietary Cache version of MUMPS runs on Windows and Linux – Open Source GT.M(Greystone Technology M) version of MUMPS also getting bundled recently with VISTA runs on GNU/LINUX. Non Linux with custom license. • Gateways for Modern Languages such as JAVA, .NET, PHP to develop Web based Client Apps – Cache Object Script – M2Web is Open Source Web Gateway to MUMPS to use with VISTA – MGWSI module from M/Gateway group to act as Gateway between Cache, GT.M M21 MUMPS databases • CPRS(Computerized Patient Record System) client-server graphical interface in Delphi to the clinicians to review, update EHRs Cache/GT.M (MUMPS) MGWSI/M2Web Java, PHP, .NET etc…
