I have been assigned to create the following tables
I want to know what is the use of SoftwareCategoryFeatureCross, SoftwareCategoryCross, SoftwareFeatureCross tables in the design. How should I manage these on the front end design.
So, this is how it's designed.
As far as Front End design is concerned, you can show all the softwares in a tabular form, with capabilities to filter by features and/or categories (or tag each software record with multiple features/categories). Clicking on any particular row will show all the categories and features for that software (using JOIN
query).
