Patterns & Quality Attributes Research

[Michael Skeen]

Dear Haskell Compiler Community,

We are doing undergraduate research on software architecture patterns and
quality attributes for Utah Valley University.  We recently analyzed the
work published on Haskell Compiler in the Architecture of Open Source
Applications <http://aosabook.org/en/index.html> (AOSA) and referenced it
in a paper we presented at the 13th Working IEEE/IFIP Conference on
Software Architecture (WICSA), as attached.  As a part of our continuing
research we wish to validate our architectural analysis for Haskell
Compiler with the current developers.

We would like to know if we are missing any patterns or quality attributes
that may have been included in Haskell Compiler, or if there are any we
listed that aren’t used. Any additional comment on these topics you might
have would also, of course, be welcome.

We believe we found the following software architectural patterns in this
application:

Pattern Name

Is This Found in the Architecture? (yes / no / don’t know)

Comments (optional)

Interpreter


Layers


Pipes & Filters


Plugin


Rule-Based System


Other?


We also identified the following quality attributes:

Attribute Name

Is This Found in the Architecture?

Comments (optional)

Scalability


Usability


Performance


Portability


Reliability


Portability


Maintainability


Testability


Modularity


Robustness


Other?



For your convenience, we have a complete list below of the patterns and
quality attributes we referred to when conducting our research. To clarify,
we are specifically studying architectural patterns, rather than design
patterns such as the GoF patterns.

Thank you for considering our request, and for your continued work on
Haskell Compiler.
