ObjectVision is a forms-based programming environment from Borland. It is different from others in that all "programming" is done using decision trees rather than a programming language. ObjectVision can read and write Paradox, Btrieve, Dbase III, and III Plus databases.

Genera is a commercial operating system and integrated development environment for Lisp machines developed by Symbolics. It is essentially a fork of an earlier operating system originating on the Massachusetts Institute of Technology (MIT) AI Lab's Lisp machines which Symbolics had used in common with Lisp Machines, Inc. (LMI), and Texas Instruments (TI). Genera is also sold by Symbolics as Open Genera, which runs Genera on computers based on a Digital Equipment Corporation (DEC) Alpha processor using Tru64 UNIX. the programming language Lisp. software using a mix of programming styles with extensive support for object-oriented programming.

Oracle Database Designer is a database model generation tool and database editing environment for Oracle Databases and ODBC compatible database. It is a "lower cost" and less powerful product than Oracle Designer/2000.

Oracle Designer, originally known as Oracle CASE is a development tool based around the idea of "Computer Aided Software Engineering" that uses a design repository and data modeling. Designer, and later versions of CASE are built around the Oracle Forms environment.

These are development tools, mainly SQL Plus, for use with an Oracle Database.

IBM's semi-often correspondence for OS/2 development.

Originally released in 1985 by Ansa Software and later sold to Borland, Paradox is a high-speed relational database product that integrates with Borland's "Turbo" products. It was notable for its Query By Example feature, and its Paradox Application Language. It was popular in the late 80s and early 90s, and competed against database product such as dBase, Symantec Q&A, Foxpro, Clipper, Clarion, DataEase, R:Base, and DataFlex.

Pascal/MT+ is an ISO 7185 compatible Pascal compiler sold by Digital Research as part of their CP/M product line. There were versions for CP/M-80, CP/M-68k, CP/M-86, and MS-DOS.

PDC Prolog, by Prolog Development Center, is an enhanced implementation of the Prolog language (a language associated with artificial intelligence development). Some early versions were marketed and published by Borland under the name "Turbo Prolog".

Phase3 is a collection of design tools you can use to build a complete database application to run under Windows 3.x. From your design, Phase3 will generate code in C or Pascal to create a complete, stand-alone source program in your target language. Phase3 will then execute your nominated compiler to compile the final stand-alone Windows-executable EXE file. time and to re-generate the source code as required. You can also write your own Pascal of C code at any point in the application. You can do this directly within Phase3 without having to modify the generated source code. (RDBMS) for storing and manipulating your application's data.

The SDK for creating Windows CE and Windows Mobile applications.

PowerBASIC is a continuation of Borland TurboBasic maintained by its original author, Robert S. Zale. It was originally notable as a BASIC compiler, when most BASIC environments were interpreted.

PowerBuilder, by Powersoft and later Sybase, is a development environment for building business application that uses the object-oriented "Powerscript" programming language. Primarily targeted at enterprises, it featured the ability to quickly and visually create powerful database programs under Microsoft Windows without having to worry about the complexities of C/C++ and the Windows SDK. It supports operation with many high end databases such as Microsoft SQL Server and Oracle Database Servers.

Power C, from Mix Software, was a low cost DOS-based C compiler targeted at the educational market. Earlier versions were known as Mix C

Microsoft QBasic, not to be confused with QuickBasic, is a stripped down version of the Microsoft QuickBasic product that replaces GW-Basic in MS-DOS 5.0 and later. QBasic is an interpreter only, and can not compile standalone executables. QuickBasic sources can be compiled into binary EXE files with QuickBasic or Visual Basic for DOS.

Microsoft QuickBasic, not to be confused with the lesser QBasic, was a Basic interpreter and compiler product loosely based on GW-Basic. Version 2.0 for DOS and later included an Integrated Development Environment. Microsoft also produced QuickPascal and QuickC with similar integrated environments.

Microsoft QuickC is a C compiler with an Integrated Development Environment, designed to compete with Borland Turbo C. It was targeted at home/hobbyist users with a much lower price tag than Microsoft's corporate-oriented professional products. Microsoft also produced QuickPascal and QuickBasic with similar integrated environments.

Microsoft QuickPascal was a short-lived dialect of Pascal created specifically to compete with Borland Turbo Pascal. It incorporated many Borland-specific features at the expense of backwards compatiblity with the earlier Microsoft Pascal product.

Quickpro Plus is a programming utility that automatically creates simple custom database applications as standalone BASIC program source files. The Quickpro Plus user can then take the resulting BASIC program and customize it further. It features reporting functionality, database calculations, and the ability to target multiple BASIC variants. There were versions for CP/M, DOS, TRS-80, Atari, and OASIS.

Quicksilver, originally named WordTech dBIII Compiler, is a dBase III Plus application compiler that produces high-speed ready to run standalone executables. It boasts assembler level speeds often faster than competing compilers. Plus clone. Both of these add a number of features such as Windowing, user defined functions, EMS memory support, graphing, and networking capability.
