| Abstract: | A recent study of development tools conducted by Software Productivity Research Inc. in Massachusetts for a software productivity consortium ranked Smalltalk first in most categories. The article discusses the major technical challenges addressed by Smalltalk implementers and application developers working on a wide spectrum of applications. To support a variety of platforms, Smalltalk uses a virtual machine approach to portability that allows applications to be easily migrated between platforms with little or no change to the code. While multilevel client server architectures seem to be the wave of the future, a large percentage of corporate data still lives in mainframes. The message-oriented nature of Smalltalk makes it a natural for concurrent and distributed object computing. However, the symbolic nature of Smalltalk relies heavily on a single, shared object space, and such issues as safe multithreading and concurrent garbage collection need to be addressed to build large-scale applications. |
