According to GSOC 2013 timeline, the coding period begins tomorrow. It's quite exiting as we get to do some hands on coding. I have pretty much completed reading documentation and getting myself familiarize with the code. Meanwhile I pulled merge requests for a couple of bugs and those fixes were incorporated to the code.
I am going to implement 'Improve relational view interface' feature during the first week. This is based on feature requests RFE #1283, RFE #1233 and RFE#175 from the feature request tracker. I've done some investigations related to these features during the last week.
With the implementation choosing the foreign column would be made a two step process. First the user chooses the foreign table from the table drop down which would filter the column in the columns drop down accordingly. Hence choosing the correct column would be much easier. Finally, the relational system would be enhanced to support cross database relations. Relational view interface would facilitate adding/editing these relations with an additional drop down to chose the database.
I will use 'relView' branch of my repository to implement this feature. However it is still empty, I will make a commit when the new code is stable. link
