No Subject - FM Thesis

<p>Yet again, it&#39;s been way too long since my last post. &nbsp;While I have been busy with other things, I haven&#39;t been <em>completely</em>&nbsp;slacking off.</p>I&#39;ve been reading and browsing through a variety of papers the last few weeks. &nbsp;I&#39;ve looked through a few on formal database specification in Z, as I mentioned last time (a couple by de Barros and one by Simpson and Martin). &nbsp;The basics are actually quite intuitive: a relational database schema maps more or less directly to a Z schema. &nbsp;The Z schema just allows for a greater level of abstraction and more detailed constraints.<br /><br /><p>I also looked at a case study using light-weight formal methods to review a GIS/database system (A Case Study using Lightweight Formalism to Review an Information System Specification, by Fiona Polack). &nbsp;This one used SAZ, a combination of Z with SSADM. &nbsp;Rather than a verification or design effort, this one was a review carried out more or less in parallel with development. &nbsp;The goal was, apparently, detection of defects, rather than straight reduction of development costs.<br /></p><p>Other than that, I&#39;ve been trying to build up and organize ideas for the paper. &nbsp;I&#39;ve got several general topics I&#39;m thinking of covering. &nbsp;There&#39;s the general FM overview, various case studies, the uses and pro/con arguments, and probably something on tools. &nbsp;The interesting parts&nbsp;(I&nbsp;hope) will be specific applications of FM to information systems and business type software in particular, as well as some consideration of the methods in &quot;formal methods&quot;. &nbsp;In other words, how to actually apply FM, rather than focusing just on the formalism, which seems quite comon.</p><p>OK, enough for tonight. &nbsp;I&#39;m missing <em>House</em>.<br /></p>

    Well...

    Sigh.... I'm almost done. I came back to it after I got laid off last winter, and ended up putting it on temporary hiatus this past spring when I was working a lot of overtime. My goal is to finish my thesis this month or next so that I can defend it in the fall semester and be done.
