Older compilers were designed according to a pipe and filter architecture, in which each stage would transform its input into an intermediate representation passed to the next stage. Modern development environments, including compilers integrated into interactive development environments with syntactical text editors and source-level debuggers, use a repository architecture. Identify the design goals that may have triggered the shift from pipe and filter to repository architecture.
What will be an ideal response?
Older compilers trace their lineage to batch systems, in which a stack of cards were fed to the computer by system
administrators and developers would pick up the resulting printout later in the day. The design goal of such system
was high throughput, so that as many jobs as possible could be executed. A pipe and filter architecture allows
parallelism between subsequent stages in the pipeline and achieves this design goal.
Modern interactive development environments are interactive, compilation occurs incrementally as the user types.
The design goal of such environments is a short response time.
