Modeling, Simulation, Prototype, Applications Programming, Object-Oriented Programming, Case Study, Application Development Software, Research and Development, and ParcPlace-Digitalk Smalltalk/V (Application development software) -- Usage
Tiny Tim (toolboxes for interactive modeling) is a Smalltalk object-oriented Programming (OOP) language-based collection of toolboxes that facilitates the description, development and programming of complex graphic models and their animation. Tim is part of the Modeller's Workbench, which provides a OOP framework for system simulation and prototyping. Other components of the workbench include the Pose queueing network simulator; Esop, which provides 'expert device during model construction and execution;' and an expert system shell, Stress, which is used in the Tim environment. Smalltalk's OOP metaphor, desktop programming environment, and collections of predefined classes for rapid prototyping of interactive graphical applications is demonstrated through the use of a Tim toolbox for creating a Monte Carlo model for analyzing the 'effectiveness of a batch of lovepotion.'

Applications, Software Migration, Micro-Mainframe Communication, DBMS, Program Development Techniques, Applications Programming, Case Study, Prototype, Compiler/decompiler, Application Development Software, BMC Software Inc. -- Product development, DB2 (DBMS), and OS/2 Database Manager 1.3 (Data base management system) -- Usage
BMC Software Inc's use of IBM's OS/2 Database Manager and other PC software tools to simulate the DB2 environment on OS/2 is described, focusing on how the company was able to work out the differences between SQL precompilers, SQL implementations and C language compilers. BMC's Change Manager was the first DB2 product developed by the company on a PC; the three Change Manager components based on existing assembly language code were kept on the mainframe, although one was rewritten in C. The new code, representing about half of the finished product, was developed and tested on the PC using IBM's OS/2 Database Manager version 1.3, Mortice Kern Systems Inc's LEX and YACC parser generator tools, and Microsoft's C version 6.0. The code was ported to the mainframe using IBM's DB2 SQL precompiler and SAS Institute's SAS/C version 5.0. The benefits provided from use of the PC platform are described, and the development process is examined.
