mvBase is a MultiValue database application which resides on the Windows operating system. The Windows operating system controls the computer system consisting of a central processing unit (CPU), random access memory (RAM), Network Interface Card (NIC), one or more hard disks, CD-ROM, floppy diskette drives, and optional peripheral devices such as multiple serial terminals, printers, tape backup devices, CD-ROM write devices and modems.
The specific hardware configuration depends upon your intended use of the mvBase application in your business. (The hardware-specific details of your mvBase application can be found in the mvBase Installation Guide and/or Release Notes that were shipped with your software.)
The mvBase Server operates as a single, highly multithreaded Windows application or service, and provide a multiuser MultiValue operating environment. While mvBase is a completely contained operating environment of its own, it is designed to make use of many features available to the Windows operating system and its network capability.
Additionally, mvBase-specific commands, as well as enhancements to the mvBASIC programming language and command line interface, provide for:
Controlled interaction with the Windows operating system and file system, allowing for convenient and easy transfer of data between the two environments.
Access to peripheral devices such as printers, backup tape devices, and floppy disk drives (which mvBase uses as tape drives).
From the Window host operating system, there is no direct access available to the mvBase operating environment. All connectivity which occurs is initiated from within mvBase.
The mvBase Server loads as any other Windows application does, with the additional option of running as a service in the Windows environment. Once started, mvBase provides a complete MultiValue database development and operating environment.
The mvBase system manages all of its data through a collection of files hosted on the Windows file system called virtual memory storage files. These files are visible in the Windows file system; however, their contents are not meaningfully viewable or accessible directly from Windows programs. These files, however, can be copied, backed up, or even deleted from the Windows operating system using standard Windows tools and techniques.

NOTE |
Virtual memory storage files can be created, deleted and resized after installation (following the parameters outlined for the Windows system on which mvBase is installed). Such file configuration requires the Windows-based mvBase Administration Utility. |
