Master Project Update: the end is approaching

with one comment

Hi all!

Well, the title says it all, the end of my master’s project is in sight!

The application is ‘nearly done’, there are so many things that could be improved but… well, there is not much time. So, let’s say that the application is at the beta stage then. Yesterday I tried to use it on a real data source instead of my toy database of only 10 records. The results were promising and today I’m processing some of the things we encountered yesterday. For instance the parsing of dates into a Java Date instance is problematic. The format of the date is not always the same and automatically detecting the format used is nearly impossible. Therefore the user (/you) can now define the format used to represent the date and time.

Another type of problem we encountered was related to the ODBC driver but that I can not fix… Other improvements are related to me trying to be too smart (which of course turns out wrong). And some performance issues (but these might be related to the ODBC driver used). And of course a lot of small improvements to the user interface can/should be made etc. So much to do, so little time 🙂

Early this week I also ‘finished’ the visualization of the conversion. The idea is to visualize which tables and columns are used in certain attributes. In the screenshot below a very small event log (with one event definition) is visualized. The conversion uses 2 columns of the event.csv table. I know that the visualization shown is very small and larger visualizations will get messy but it’s hard to get it right… And, well, its only a prototype 😉

I’m also working on my thesis, for about a month now. The contents is structured as follows:

  1. Introduction (context, problem, goal, scope and method of the project) [4 pages]
  2. Preliminaries (explanation of process aware information systems (PAIS), event logs, process mining and other conversion tools) [12 pages]
  3. Conversion Aspects (what to consider when defining a conversion) [8 pages]
  4. Solution Approach (how I planned to implement the application) [7 pages]
  5. Solution Implementation (more details of the technical implementation and use of the application) [14 pages]
  6. Case Studies (2 case studies (SAP and a custom system) to show the validity of my application) [to write]
  7. Conclusion (conclusions and future work) [to write]

So, I still have to perform my case studies, write Chapters 6 and 7 plus the abstract, preface etc. and thoroughly read the entire thesis. And all of that within the next 2 to 3 weeks. And then I’ll have to wait for the reviews of my supervisors and prepare for the final presentation of March 29…

You are all invited for my final presentation of course!!! It will be held at March 29 2010 at 15:00 in Eindhoven, the Netherlands. If you like to attend, please let me know then I’ll inform you of the location.

If you can not attend the final presentation and/or want to read my thesis or try out my application, keep an eye on this blog. I’ll post a link to both of them just before or after my final presentation.

So, now I’m going back to programming again (stupid SQL error…) and enjoy the weekend in a little bit.

TTFN!
