Java Development Tools

Hi Experts,

Please advice how to achieve this UX ***Moderator action: removed link to external page as it's considered spam *** in ADF, my database table to store values looks like below:
functionality needed:

1. Add columns , each column is unique role from predefined list.
2. Add row, unique for combination of app, field, field value, role id.
3. highlight Roles cell with changed activation/disabled status, added roles, added rows etc.

I already achieved it with brute force of 150 max transient variables in my VO which works on complicated pivot query, but many issues / incomplete functionality hitting too many roadblocks; i want advice on how to proceed and change approach so UX and required features.
