Visual FoxPro

Company / developer:
  Microsoft Corporation

Visual FoxPro

Visual FoxPro is a data-centric object-oriented and procedural programming language by Microsoft. It is derived from FoxPro (originally known as FoxBASE) which was developed by Fox Software beginning in 1984; Fox Software merged with Microsoft in 1992 and the software acquired further features and the prefix "Visual". The last version of FoxPro (2.6) worked under the Mac OS, DOS, Windows, and Unix: Visual FoxPro 3.0, the first "Visual" version, dropped the platform support to only Mac and Windows, and later versions were Windows-only.

Visual FoxPro, also known as VFP, is mainly used to write desktop database applications running on Windows but it can also be used to write fat client, middleware, and web applications.

In late 2002, it was demonstrated that Visual FoxPro can run on Linux under the Windows emulator Wine. In 2003, this led to complaints by Microsoft: it was claimed that the deployment of FoxPro code on non-Windows machines violates the End User License Agreement.

Rumors suggesting that Microsoft intends to end support for FoxPro have been common since Microsoft's acquisition of the product, despite the product having one of the longest support timeframes for a Microsoft product (extended support until 2014). VFP 9 was released to manufacturing on December 17, 2004, and the Fox team is currently working on a project codenamed Sedna which will be built on top of the VFP9 codebase.

Microsoft Windows

Company / developer:
  Microsoft Corporation

Microsoft Windows

Microsoft Windows is a family of operating systems by Microsoft. They can run on several types of platforms such as servers, embedded devices and, most typically, on personal computers. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing trend of graphical user interfaces (GUI) popularized by the Macintosh. Microsoft Windows eventually came to dominate the world's personal computer market.

Unix

Unix

Unix operating systems are widely used in both servers and workstations. The Unix environment and the client-server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.

Both Unix and the C programming language were developed by AT&T and distributed to government and academic institutions, causing both to be ported to a wider variety of machine families than any other operating system. As a result, Unix became synonymous with "open systems".

Unix was designed to be portable, multi-tasking and multi-user in a time-sharing configuration. Unix systems are characterized by various concepts: the use of plain text for storing data; a hierarchical file system; treating devices and certain types of inter-process communication (IPC) as files; and the use of a large number of software tools, small programs that can be strung together through a command line interpreter using pipes, as opposed to using a single monolithic program that includes all of the same functionality. These concepts are known as the Unix philosophy.

Under Unix, the "operating system" consists of many of these utilities along with the master control program, the kernel. The kernel provides services to start and stop programs, handle the file system and other common "low level" tasks that most programs share, and, perhaps most importantly, schedules access to hardware to avoid conflicts if two programs try to access the same resource or device simultaneously. To mediate such access, the kernel was given special rights on the system, leading to the division between user-space and kernel-space.

The microkernel concept was introduced in an effort to reverse the trend towards larger kernels and return to a system in which most tasks were completed by smaller utilities. In an era when a "normal" computer consisted of a hard disk for storage and a data terminal for input and output (I/O), the Unix file model worked quite well as most I/O was "linear". However, modern systems include networking and other new devices. As graphical user interfaces developed, the file model proved inadequate to the task of handling asynchronous events such as those generated by a mouse, and in the 1980s non-blocking I/O and the set of inter-process communication mechanisms was augmented (sockets, shared memory, message queues, semaphores), and functionalities such as network protocols were moved out of the kernel.
