Visual Objects
Visual Objects ( VO ) is an object-oriented programming language for 32-bit platforms. It is used to develop applications for operation under Windows .
VO is a general development tool that has a complete IDE and generates executable .EXE and .DLL files independently of other products or licenses. Due to the history of its origins , it is often used to develop database applications .
Emergence
The Visual Objects project (code name Aspen ) originally resulted from the idea of porting the Clipper programming language to Windows and further developing the procedural Clipper into an object-oriented language. In addition, the developer company at the time, Nantucket, provided the new product with a machine code compiler and introduced additional C language elements ( e.g. typed variables ) in order to be able to integrate Windows extensions ( e.g. COM, ODBC, ADO ). In the development phase (1992) Nantucket was bought by Computer Associates (CA). At that time, Aspen was a purely German project led by Dr. Alexander Burak Kozan. Other members of the Aspen team were Lothar Bongartz, Gunnar Main, Frank Mantek, Uwe Holz, Ralf Saborowski and Dietmar Bos.
Current version
Visual Objects Version 1.0 was distributed by CA in the 4th quarter of 1994. Version 2.8 (service pack 4) of VO is currently on the market (as of spring 2013). A .NET further development is available under the name Vulcan.NET in version 2. In 2003 CA transferred the further development and marketing of VO to GrafXSoft.
On December 31, 2017 GrafX Database Systems Inc. ceased operations according to its own homepage.
